    In this case we address whether a noncustodial parent, receiving social security disability benefits at the time he enters into a child support consent order, is entitled to a modification of child support after his minor child applies for and receives social security disability dependency benefits. We hold that the parent who sought modification of the child support award was unable to show a material change in circumstances justifying the exercise of the court's discretion to modify the parent's child support obligation. We also hold that although a noncustodial parent may be entitled to a modification of a child support award when his or her child receives social security disability dependency payments, the noncustodial parent is not entitled to an automatic credit against the child support obligation equal to the amount of social security disability dependency benefits received by the minor child; a court in its discretion may, if the circumstances warrant, adjust the amount of the child support obligation of the parent consistent with the child support guidelines. We shall affirm the judgment of the Circuit Court for Allegany County that neither allowed such a credit nor modified the parent's support obligation.

    On October 25, 1994, the State, to the use of Shirley A. Drummond, filed in the Circuit Court for Allegany County a complaint seeking child support from James A. Drummond, appellant. In appellant's answer to the complaint, he stated that he was unable to work because "he is totally disabled and has been found to be so disabled by the United States Social Security Administration." Thereafter on March 24, 1995, appellant and Mrs. Drummond entered into a consent order for child support under which appellant was ordered to pay $38 per month for the support of his minor son, Joshua M. Drummond.

    In July of 1995, Joshua began receiving social security disability dependency benefits of $53 per month. Thereafter, on August 1, 1995, appellant moved to modify the child support order on the ground that Joshua was receiving from the Social Security Administration social security disability dependency payments and that those payments should be credited against appellant's support obligation. A master's hearing for reduction in child support was held on December 5, 1995. During that hearing, Mrs. Drummond testified that she was receiving Aid to Families with Dependent Children (AFDC) benefits of $247 per month, Joshua was receiving social security disability dependency benefits of $53 per month and child support payments from appellant of $38 per month. Mrs. Drummond also testified that the AFDC benefits were reduced from $292 per month as a result of the social security disability dependency payments Joshua began receiving in July of 1995.⁽¹⁾ Appellant testified that he received $425 per month in social security disability benefits and $53 per month in supplemental security income (SSI) benefits.

    The master, mistakenly finding that the child received "$425.00 per month in Social Security Disability benefits and SSI benefits of $53.00 per month," concluded that the "child appears to be totally emancipated at least financially as a result of these particular benefits," and recommended that support be suspended. The State filed timely exceptions to the master's recommendation. The Circuit Court for Allegany County held that the master erred in suspending appellant's child support obligation because the master erroneously found the child was receiving $478 per month. The court remanded the matter to the master "for the purpose of calculating support under Sec. 12-204(e) by using that aspect of the guidelines that provides for support within the range of $20 to $50 per month, 'based on resources and living expenses of obligor.'"

    A second master's hearing was held on January 28, 1997. Finding that appellant was not entitled to a modification, the Master stated:

    Appellant filed exceptions to the master's recommendations asserting that "the Master erred in finding that [appellant] was not entitled to a credit against his child support obligation for the Social Security disability payment currently being made directly to his minor child, Joshua Drummond." On July 1, 1997, the circuit court, in a written order, accepted the master's findings, conclusions, and recommendations.

    Appellant filed a Notice of Appeal on July 31, 1997. We issued a writ of certiorari to the Court of Special Appeals prior to argument in that court. We hold that the Circuit Court for Allegany County did not err in denying appellant's request to modify the child support obligation.

    Two methods are available by which a parent may obtain modification of a child support award. First, pursuant to Maryland Code (1984, 1991 Repl. Vol), section 12-104 of the Family Law Article (FL), a court may modify a child support award "subsequent to the filing of a motion for modification and upon a showing of a material change of circumstance." A court also may modify a child support award pursuant to section 12-202(b)(1) of the Family Law Article, which states that "the adoption of the guidelines set forth in this subtitle may be grounds for requesting a modification of a child support award based on a material change in circumstances." The adoption of the guidelines may not be the basis for a modification of child support "unless the use of the guidelines would result in a change in the award of 25% or more." FL § 12-202(b)(2).⁽³⁾ As the award appellant seeks to have modified post-dates the adoption of the guidelines, section 12-104 of the Family Law Article is the only statutory provision under which appellant may seek a modification of the child support award in this case.

    Section 12-104 allows a court to modify a child support award only after the filing of a motion for modification and a finding of a material change in circumstances. We explained the limitation on the trial court's authority to modify a child support award in Wills v. Jones, 340 Md. 480, 488-89, 667 A.2d 331, 334-35 (1995):

The trial court, after finding a material change in circumstances, must then apply the child support guidelines of sections 12-202 to 12-204 of the Family Law Article in order to determine the level of support to which the child is entitled. Wills, 340 Md. at 491, 667 A.2d at 336.

    Although there are various ways a change in circumstances could be relevant to the modification of a child support award, there are two obvious ways in which a change is relevant to the level of support a child actually is receiving or entitled to receive. "First, a relevant change in circumstances may occur upon the passage of some event causing the level of support a child actually receives to diminish or increase." Wills, 340 Md. at 488 n.1, 667 A.2d at 335 n.1. A second relevant change in circumstance may occur when there is a change in the income pool used to calculate the child support obligation.

    We examined a potential change in circumstance causing the level of support a child actually receives to diminish or increase in Walsh. In that case, a prior support order required the noncustodial parent to pay child support in an amount below the amount provided for in the child support guidelines. The order also permitted the custodial parent to use the family home and required the noncustodial parent to pay one-half of the mortgage. Prior to the hearing on the modification, the parents entered into an agreement whereby the custodial parent would purchase the noncustodial parent's interest in the family home. Consequently, the noncustodial parent's obligation to pay one-half of the mortgage ceased.

    Holding that a remand was necessary to determine whether there was a material change in circumstance pursuant to section 12-104, we stated:

Walsh, 333 Md. at 502-03, 635 A.2d at 1345 (footnote omitted).

    A second common change in circumstance relevant to a modification of child support is a change in the income pool from which the child support obligation is calculated. In Wills, 340 Md. at 488 n.1, 667 A.2d at 335 n.1, we noted that an example of a relevant change in the income pool could be one parent losing his or her job. We went on to note that a parent's incarceration would be a relevant change in circumstance that had an effect on the income pool because the incarceration would make it impossible for the parent to maintain employment. Id. at 488-89 n.1, 667 A.2d at 335 n.1.

    In Petrini v. Petrini, 336 Md. 453, 648 A.2d 1016 (1994), we affirmed the trial court's consideration of non-cash gifts to a parent in determining the parent's actual income and thereafter calculating the father's child support obligation. Addressing the parent's contention that the gifts he was receiving were not indefinite, we noted that if at some point the parent no longer received the gifts, he could request a modification of his child support obligation based upon a material change in circumstances. Id. at 467, 648 A.2d at 1022. See also Moore v. Tseronis, 106 Md. App. 275, 664 A.2d 427 (1995) (noting that parent's relocation to a rural area and subsequent reduction in salary resulting from the relocation constituted a material change in circumstances); Lieberman v. Lieberman, 81 Md. App. 575, 568 A.2d 1157 (1990) (affirming trial court's finding of a material change in circumstances when parent's net income rose from $200,000 to $386,800).

    Not only must there be a change in circumstances, it must be material. That is, the change must be of a significant degree so as to support the modification. With respect to the materiality of the change in circumstance, a trial court "[i]n making this threshold determination that a material change of circumstance has occurred . . . must specifically focus on the alleged changes in income or support that have occurred since the previous child support award." Wills, 340 Md. at 489, 667 A.2d at 335 (emphasis added).

    In setting child support obligations, a court is required to utilize the child support guidelines. There is a rebuttable presumption that the amount of child support resulting from the application of the guidelines is correct. FL § 12-202; Walsh, 333 Md. at 498, 635 A.2d at 1343. In calculating a child support award, a court first must determine the adjusted actual income of each parent, as defined in section 12-201. See Petrini, 336 Md. at 461, 648 A.2d at 1019-20. It then adds the adjusted actual income of both parents to arrive at the combined adjusted actual income. FL § 12-201(e). A court next determines the basic child support award "in accordance with the schedule of basic child support obligations in subsection (e) [of section 12-204 of the Family Law Article]." FL § 12-204(a)(1). The basic support obligation derived from the schedule in section 12-204(e) then is divided between the parents in proportion to their adjusted actual incomes. FL § 12-204(a). Certain child care expenses and extraordinary medical expenses incurred on behalf of a child must be added to the basic child support obligation. See FL § 12-202(g)-(h). Transportation and school expenses may also be added. See FL § 12-202(i). A court, however, may depart from the guidelines if their application would be unjust or inappropriate. FL § 12-202(a)(2)(ii).

    An examination of the child support guidelines indicates that in setting the basic child support obligation, a court looks to the adjusted actual income of the parents and the combined adjusted actual income, as those terms are defined in section 12-201 of the Family Law Article. At the time appellant entered into the consent decree and the trial court entered an order for the payment of child support, Mr. Drummond was receiving social security disability benefits of $384 per month. Appellant received an increase in his social security disability payments so that he was receiving $425 per month at the time of the hearing on his motion to modify.

    Mrs. Drummond received $292 per month in AFDC benefits at the time of the entry of the 1995 child support order. She testified that the AFDC benefit payments were reduced to $247 per month after Joshua began receiving social security disability dependency payments of $53 per month.

    Maryland's child support guidelines do not provide that income received by a child is to be considered in determining the basic child support obligation. Although the income a child receives from other sources may be a relevant consideration in departing from the guidelines, initially it is not normally part of the calculation of the basic child support obligation. Unlike Maryland's child support guidelines, many states' statutes, which we shall discuss in part IV of this opinion, expressly provide that income received by a child may be a consideration in departing from the presumptively correct child support obligation. These statutes, however, do not provide that income received by a child is to be considered in calculating the basic child support obligation. Likewise, any benefits received by a child from a source other than a child's parents generally are not relevant in determining the basic child support obligation of the parents under Maryland's child support guidelines.

    It is the parents with whom lies the legal duty to support their child. In accordance with the child support guidelines, a court normally examines only the combined adjusted actual income of the parents in order to determine the basic child support obligation. As we have explained, the combined adjusted actual income of the parents is the sum of each parent's adjusted actual income. This amount is used to determine the basic child support obligation.

    A comparison of the circumstances at the time of the entry of the original consent order on March 24, 1995, and the circumstances at the time appellant sought modification of the child support award on August 1, 1995, leads us to conclude that there was no material change in circumstances in this case justifying a downward modification of the child support award. At the time of the initial order, appellant was receiving $384 per month in social security disability payments. He was receiving $425 at the time he sought modification of the child support award. Mrs. Drummond was receiving $292 per month in AFDC benefit payment at the time of the original order, but was receiving only $247 per month in AFDC benefit payment at the time of the hearing on the modification.⁽⁴⁾ The only change in circumstance between the time of the entry of the original child support award and the time of the requested modification was Joshua's application for and receipt of social security disability dependency benefits. Although Joshua was not receiving these benefits at the time of the entry of the original award, he legally was entitled to the benefit payments pursuant to 42 U.S.C. § 402(d) at that time.⁽⁵⁾

    At the time of the entry of the original award, the relevant factors in calculating appellant's child support obligation were appellant's and Mrs. Drummond's actual adjusted income. These same factors were relevant at the time appellant sought modification of his child support obligation. As we just explained, there was no substantial change in appellant's or Mrs. Drummond's actual adjusted income to justify granting appellant's motion to modify his child support award downward. The only change in circumstances related to Joshua's receipt of social security disability dependency benefits, a benefit to which he was entitled at the time appellant entered into the consent decree and at the time the original decree was signed by the court. ⁽⁶⁾

    Following the child support award in 1995, Joshua's family unit received $330 per month ($292 + $38). After Joshua began receiving social security disability dependency benefits, the AFDC benefits Mrs. Drummond received decreased to $247 per month. These AFDC benefits were paid to Mrs. Drummond on account of Joshua.⁽⁷⁾ Following Joshua's receipt of the social security disability dependency benefits, the family unit to which Joshua belonged had an income of $338. We do not believe this change in income to Joshua's family sufficiently substantial so as to constitute a substantial change in circumstances warranting the modification of appellant's child support obligation.

    We note that if appellant were concerned about Joshua's receipt of social security disability dependency benefits, he could have requested a departure from the guidelines at the time of the original order, as he was aware of his disability at that time. He did not do

so. Instead, he signed a consent decree obligating him to pay support of $38 per month.

    Even if appellant were able to show a material change in circumstances so as to give a court authority to modify his child support award, appellant's assertion that he is "entitled to a credit against his child support obligation for the Social Security disability payment currently being made directly to his minor child, Joshua Drummond" still would be unavailing.

    Once a court finds that a material change of circumstances has been shown, the court computes the level of support to which a child is entitled using the child support guidelines. See Wills, 340 Md. at 491, 667 A.2d at 333. Given the relatively small change in the parents' actual income in this case, application of the child support guidelines would not lead to a child support award different than that awarded pursuant to the initial order. Although the child support guidelines provide for the addition to the basic child support guidelines of certain expenditures, FL § 12-204(g)-(i), there is no provision authorizing a court to grant a credit to a parent for income received by the child from some other resources such as income derived from a child's employment, investments, or gifts. In order to depart from the presumptively correct child support award calculated in accordance with the child support guidelines, a court must do so consistently with the statute. The statute permits a departure from the guidelines when "the application of the guidelines would be unjust or inappropriate." FL § 12-202(a)(2)(ii). We do not perceive this to be such a circumstance.

    The Court of Special Appeals in Anderson v. Anderson, 117 Md. App. 474, 700 A.2d 844 (1997), vacated on other grounds, 349 Md. 294, 708 A.2d 296 (1998), examined whether a parent was entitled to receive a credit against child support for social security retirement benefits being paid directly to his minor children. Judge Eyler, writing for the court, stated:

Anderson, 117 Md. App. at 484-87, 700 A.2d at 849-50 (emphasis added).

    Although section 12-202(a) does not specifically provide that income received by a child is to be considered as a factor in deviating from the guidelines, we agree with the Court of Special Appeals that the receipt of income by a child may be a relevant factor in determining whether "the application of the guidelines would be unjust or inappropriate." FL § 12-202(a)(2)(ii). A trial court has the discretion to deviate from the child support award calculated pursuant to the guidelines if, after considering income of a child, their application would be unjust or inappropriate in a particular case. This approach is consistent with other states' child support guidelines, which explicitly provide that a child's income may be a factor in determining whether to deviate from the guidelines. See Ala. R. Jud. Admin. 32(A)(1)(d); Alaska Civ. R. 90.3(c); In re Guidelines for Child Support, 314 Ark. 644, 863 S.W.2d 291, 295 (1993); Fla. Stat. Ann. § 61.30(11)(b) (West 1997 & 1998 Supp.); Ill. Rev. Stat. ch. 750, para. 5/505(a)(2)(a) (1993 & 1998 Supp.); Ky. Rev. Stat. Ann. § 403.211(3)(d) (Michie 1984 &1996 Supp.); La. Rev. Stat. Ann. § 9:315.7 (West 1991 &1997 Supp.); Me. Rev. Stat. Ann. tit. 19, § 2007.3.D (West 1998); Michigan Child Support Formula Manual 4 (1998); Minn. Stat. Ann. § 518.551(c)(2) (West 1990 &1998 Supp.); Miss. Code Ann. § 43-19-103(b) (1993); Mont. Admin. R. 46.30.1543(1)(m); N.J. Ct. R., Appx. IX.21(l); N.Y. Fam. Ct. Act § 413.1(f)(1) (McKinney 1998); Tex. Fam. Code Ann. § 154.123(b)(3) (West 1996); Vt. Stat. Ann. tit. 15, § 659(a)(1) (1989 & 1997 Supp.); Va. Code Ann. § 20-108.1.B.9 (Michie 1995 &1998 Supp.); Wa. Rev. Code § 26.19.075(vii) (1994). Cf. Idaho R. Civ. Pro. 6(c)(6) Section 10(d)(1) (permitting examination of income of a child when parents' income exceeds $150,000).

    An automatic credit for social security disability dependency benefits received by a child, however, is unavailable to the noncustodial parent under the Maryland child support guidelines. A trial court has the discretion to deviate from the guidelines only when their application would be unjust or inappropriate. This view is in accord with that of other states that have held a trial court may consider a child's receipt of social security disability dependency benefits and has the discretion to deviate from the child support guidelines under the appropriate circumstances. See Graby v. Graby, 87 N.Y. 2d 605, 611, 664 N.E.2d 488, 491 (1996) ("Social Security benefits paid to petitioner's dependents on the basis of his disability are 'financial resources' of the children that should be considered by the court after the basic support obligation is calculated and only then pursuant to a[n] . . . 'unjust or inappropriate' determination."); Stultz v. Stultz, 659 N.E.2d 125 (Ind. 1995) (noting trial court has discretion to determine whether to credit social security disability dependency payments received by the child toward a noncustodial parent's child support obligation); In re Marriage of Lawhorn, 119 Or. App. 225, 850 P.2d 1126 (1993) (holding trial court may consider social security disability dependency benefits received by the child and may deviate from the application of the child support guidelines if application of the guidelines is unjust or inappropriate). See also Griffin v. Avery, 120 N.H. 783, 424 A.2d 175 (1980) (noting in a case prior to adoption of child support guidelines that trial court has discretion to determine whether to grant obligor parent a credit); Nibs v. Nibs, 625 P.2d 1256 (Okla. 1981) (holding prior to adoption of child support guidelines that a credit was discretionary); Davis v. Davis, 141 Vt. 398, 449 A.2d 947 (1982) (holding noncustodial parent not entitled to an automatic credit and court could order child support in addition to social security disability dependency benefits); Hinckley v. Hinckley, 812 P.2d 907 (Wyo. 1991)(indicating trial court has discretion to modify child support award due to social security disability dependency benefits received by children).

    In addition to being consistent with the child support guidelines, this approach is consistent with the often-enunciated policies of this State regarding child support and children generally. A parent has both a common law and statutory duty to support his or her minor child. See FL § 5-203(b); Garay v. Overholtzer, 332 Md. 339, 368-69, 631 A.2d 429, 432 (1993); Middleton v. Middleton, 329 Md. 627, 632-33, 620 A.2d 1363, 1365 (1993); Carroll County Dept. of Social Servs. v. Edelmann, 320 Md. 150, 170-71, 577 A.2d 14, 23 (1990). We previously have noted the rationale underlying a parent's obligation of support:

Knill v. Knill, 306 Md. 527, 531-32, 510 A.2d 546, 548 (1986)(quoting 1 W. Blackstone, Commentaries * 447). See also Warren v. Warren, 336 Md. 618, 629, 650 A.2d 252, 257 (1994) (quoting Knill). To relieve a parent entirely of his or her support obligation because the child receives a benefit to which he or she is entitled from some other source would not ordinarily be consistent with this fundamental principle of family law.

    Moreover, Maryland has adopted the Income Shares Model in calculating child support awards. As Judge Chasanow opined for the Court, "[t]he conceptual underpinning of this model is that a child should receive the same proportion of parental income, and thereby enjoy the standard of living, he or she would have experienced had the child's parents remained together." Voishan v. Palma, 327 Md. 318, 322, 609 A.2d 319, 321 (1992). When a parent becomes disabled and thereafter receives social security disability benefits, his or her child is generally entitled to social security disability dependency benefits regardless of whether the child's parents remain together or separate. It is the child, not the parent, who is entitled to the social security disability dependency benefit pursuant to 42 U.S.C. § 402(d). It would be inconsistent with the Income Shares Model to give a child of separated parents the benefit of only social security disability dependency payments when a child, whose parents remained together, has the benefit of both his own direct social security disability dependency payment and the indirect benefit of the social security disability payment received by the parent. Our approach gives a child whose parents have not remained together the benefit of both the social security dependency benefit and the parent's social security disability benefit through the award of child support.

    This approach also puts a child of separated parents in the same situation as a child of parents who are not separated because it allows the child to maintain the same standard of living as if the parents had not separated. See Graby, 87 N.Y.S. 2d at 612, 664 N.E. 2d at 492 ("[H]ad the marriage not been dissolved, petitioner's children would have enjoyed a standard of living based on both parents' income plus the social security benefits they received as petitioner's dependents."); cf. Stultz, 659 N.E.2d at 129 (noting in a social security retirement benefits case that if the marriage had not been dissolved, the children would have had the benefit of their parent's social security retirement benefits and their own social security retirement dependency benefit). The approach we adopt today is consistent with the Income Shares Model and also gives a court the discretion to deviate from the basic child support obligation in the appropriate circumstances to account for a benefit payment received by the child.

    We are cognizant that numerous states have adopted the position that a noncustodial parent is entitled to a credit toward his or her child support obligation for social security disability dependency payments received by his or her minor child. See Michael A. DiSabatino, Right to Credit on Child Support Payments for Social Security or Other Government Dependency Payments Made for Benefit of Child, 34 A.L.R.5th 447 (1994). The annotation lists the following states as having adopted the position that a credit is available automatically to a noncustodial parent for social security disability payments received by the child: Alabama, California, Georgia, Illinois, Indiana, Iowa, Kansas, Louisiana, Massachusetts, Michigan, Mississippi, Missouri, Nebraska, New Mexico, New York, Ohio, Rhode Island, South Dakota, Tennessee,⁽⁸⁾ and Washington. See id. at 469-70. Other state courts have adopted this same position since 1994. See Department of Revenue v. Fry, 926 P.2d 1170 (Alaska 1996 ); Miller v. Miller, 929 S.W.2d 202 (Ky. Ct. App. 1996); Holmberg v. Holmberg, 578 N.W.2d 817 (Minn. Ct. App. 1998); In re Marriage of Cowan, 928 P.2d 214 (Mont. 1996); Hern v. Erhardt, 113 Nev. 142, 948 P.2d 1195 (1997); Nazworth v. Nazworth, 931 P.2d 86 (Okla. Ct. App. 1996); In the Interest of Allsup, 926 S.W.2d 323 (Tex. Ct. App. 1996); Whitaker v. Colbert, 18 Va. App. 202, 442 S.E.2d 429 (1994).

    Although the position of some of the states seems to be that a credit is available automatically to a noncustodial parent, for numerous reasons we are not persuaded by the reasoning set forth in the cases. First, some of the states listed in the annotation either have abandoned or criticized that position.⁽⁹⁾ New York intermediate appellate courts had adopted the position that a credit was available. See Graby v. Graby, 607 N.Y.S. 2d 988 (App. Div. 1994); Passaro v. Passaro, 459 N.Y.S.2d 839 (App. Div. 1983). The Court of Appeals of New York, examining its child support guidelines, subsequently held in Graby, 87 N.Y.2d 605, 664 N.E.2d 488, however, that a credit is not available automatically against a child support obligation for social security disability dependency benefits received by the child.

    Similarly, Louisiana Courts of Appeal initially had taken the position that a credit was available to the obligor parent for social security disability dependency benefits received by the obligor's child. See Faul v. Faul, 548 So. 2d 957 (La. Ct. App. 1989); Folds v. Lebert, 420 So. 2d 715 (La. Ct. App. 1982). More recently, in Phillips v. Phillips, 673 So. 2d 333, 335 (La. Ct. App. 1996), the noncustodial parent sought modification of her child support obligation due to the social security disability dependency benefits received by her children. Affirming the trial court's refusal to allow her a credit, the court noted that a statutory provision permitted the court to consider resources received by the child and to deviate from the basic child support obligation under the appropriate circumstances. See also Gibson v. Gibson, 592 So.2d 855 (La. Ct. App. 1991) (affirming trial court's decision to order child support in addition to social security disability dependency benefits received by child).

    The Michigan Court of Appeals in Jenerou v. Jenerou, 200 Mich. App. 265, 267-68, 503 N.W.2d 744, 746 (1993), criticized the position, that an automatic credit was available, that it had adopted previously in Frens v. Frens, 191 Mich. App. 654, 478 N.W.2d 750 (1991). The Michigan Court of Appeals stated:

Jenerou, 200 Mich. App. at 267-68, 503 N.W.2d at 746.

    We also note many states that allow the obligor parent a credit toward his or her child support obligation due to social security payments received by the obligor's minor child have specific statutory provisions in their respective child support guidelines authorizing the credit. For instance, the relevant Colorado provision of the child support guidelines states:

App. 1996) (noting prior case law holding credit was discretionary and 1992 statutory provision mandating credit). Other states have similar provisions in their respective child support guidelines statutes. See Cal. Fam. Code § 4504 (West 1994 &1998 Supp.); Regs., Conn. State Agencies § 46-215a-2(b)(6); Idaho R. Civ. Pro. 6(c)(6) Section 11; Iowa Code § 598.22 (1996 & 1998 Supp.); Michigan Child Support Formula Manual 5-6 (1998); Mont. Admin. R. 46.30.1542; N.J. Child Support Guidelines, Appx.

Larson, 569 N.W.2d 512 (Iowa Ct. App.1997) (discussing availability of a statutory credit for social security disability dependency benefits received by a child); Herd v. Herd, 307 N.J. Super. 501, 704 A.2d 1340 (App. Div. 1998) (reading Appendices IX-A and 1X-B so as to require a credit to the obligor parent for social security disability dependency benefits received by child); Pasternak v.

Div. 1997) (recognizing statutory credit); In re Marriage of Briscoe, 134 Wash.2d 344, 949 P.2d 1388 (1998) (recognizing statutory credit); In re Marriage of Hughes, 69 Wash. App. 778, 850 P.2d 555 (1993) (noting statutory credit was available for social security disability dependency benefits received by an obligor's minor child).⁽¹⁰⁾ Unlike these states' statutes, Maryland's child support guidelines contain no specific statutory provision authorizing a court to grant a credit to a noncustodial parent for social security disability dependency payments received by the child due to the noncustodial parent's disability.

    Finally, we note some of the state cases that held a credit was available did so prior to their state's adoption of mandatory child support guidelines. We do not believe these courts have examined thoroughly the availability of the credit in light of the adoption of the guidelines by their respective states. Some courts, examining the availability of the credit since the adoption of the guidelines, have noted that the adoption of presumptively correct obligations has impacted the noncustodial parent's ability to obtain a credit for social security disability dependency benefits received by a child. In Guthmiller v. Guthmiller, 448 N.W.2d 643, 647-48 (N.D. 1989), the Supreme Court of North Dakota concluded that a child's receipt of such payments constituted a change in circumstances entitling the obligor to a credit against his support obligation. That court more recently examined the availability of the credit following the adoption of presumptively correct child support guidelines. It stated: "The trial court's decision in Guthmiller was rendered before the effective date of the 1989 amendments . . . making the scheduled child support under the guidelines the presumptively correct support obligation. Under the current guidelines it may or may not be appropriate to credit social security dependency payments toward the obligor's support obligation." Mehl v. Mehl, 545 N.W.2d 777, 780 (N.D. 1996). See also Austin v. Towne, 560 N.W.2d 895, 898 (N.D. 1997) (discussing availability of a credit following the adoption of the child support guidelines).

    Similarly, the Supreme Court of Kansas in Andler v. Andler, 217 Kan. 538, 544, 538 P.2d 649, 654 (1974), held that a parent ordered to pay child support was entitled to a credit toward that obligation for social security disability dependency payments made to the child. The Court of Appeals of Kansas more recently examined the availability of a credit following the adoption of child support guidelines in In re Marriage of Callaghan, 19 Kan. App. 2d 335, 869 P.2d 240 (1994). Addressing the noncustodial parent's contention that due to his childrens' receipt of social security disability dependency benefits, which were greater than his child support obligation, he was not required to pay child support, the court stated: "The husband's rationale is unfounded because the amount of his child support obligation is specifically determined by the formula within the child support guidelines. Moreover, the state guidelines, not the provisions of the Social Security Act, define the husband's child support obligation." Id. at 337, 869 P.2d at 242 (citation omitted). See also Stultz, 659 N.E.2d at 128-29 (recognizing impact of child support guidelines).

    For these reasons and because the best interests of the child is of paramount importance in Maryland, we do not believe that an obligor parent should receive an automatic credit toward his or her child support obligation in an amount equal to the benefit payments received by his or her minor child, who is entitled to the payments under federal law.

    We hold that under the circumstances of this case, appellant was unable to show a material change in circumstances so that a court would have the discretion to modify his child support award. Assuming appellant were able to show a material change in circumstances, he would not be entitled to an automatic credit against his child support obligation for social security disability dependency benefits received by his son. The proper approach is to apply the child support guidelines and, if the application of the guidelines would be unjust or inappropriate, deviate from them as provided in section 12-202(b) of the Family Law Article.

                            JUDGMENT AFFIRMED; APPELLANT TO PAY THE COSTS.

1. The payments were for Joshua although sent to his mother on his behalf. The total added income to Joshua and Mrs. Drummond as a result of Joshua's receipt of social security disability dependency benefits and the resulting reduction of AFDC benefits was $8 per month.

2. In applying the guidelines, the master considered the social security disability dependency benefits received by Mrs. Drummond on behalf of Joshua as income to Mrs. Drummond. As we shall note infra, social security disability dependency payments are made to the child. Accordingly, they are not considered income either to the custodial parent or to the noncustodial parent in the application of the child support guidelines.

3. We explained the circumstances under which section 12-202(b) was applicable in Walsh v. Walsh, 333 Md. 492, 499-500 635 A.2d 1340, 1343 (1994). Quoting from the decision of the Court of Special Appeals, with which we agreed, this Court stated:
