ISSUE PRESENTED
               You asked whether minor child H~ (the claimant), who is the biological child of B~
                  (the mother), is entitled to child’s insurance benefits on the Social Security record
                  of number holder R~ (née I~) (NH). The NH has been married to the mother since before
                  the claimant’s birth, and the NH is identified as a parent on the claimant’s birth
                  certificate. The family resides together in Missouri.
               
               SHORT ANSWER
               While the claimant is not the biological child of the NH, the NH’s parentage is presumed
                  as the claimant was born in wedlock between the NH and the mother. The parent-child
                  relationship is also established as the NH is listed as a parent on the claimant’s
                  birth certificate. A Missouri court, therefore, would likely find that the claimant
                  is entitled to inherit from the NH under Missouri intestacy law. Under section 416(h)(2)(A)
                  of the Act, the claimant is the NH’s child and deemed dependent. Accordingly, you
                  can find he is entitled to child’s insurance benefits on the NH’s record.
               
               FACTUAL BACKGROUND
               On January XX, 2015, the NH and the mother married in C~, Missouri. Approximately
                  three months later, the claimant was born on May XX, 2015, in S~ County, Missouri.
                  His birth certificate lists the mother as “mother” and the NH as “father.” The claimant
                  is the biological child of the mother. The NH does not have a biological connection
                  to the claimant. According to the NH, prior to the claimant’s conception, the couple
                  agreed that the mother should conceive the claimant with an unidentified man, who
                  reportedly has terminated his parental rights.
               
               On November XX, 2015, the claimant filed an application for child’s benefits on the
                  record of the NH.

                                       Under the Social Security Act (Act), a child of an insured worker who is dependent
                                          upon the insured may receive auxiliary child’s insurance benefits on the record of
                                          a worker who receives disability or retirement benefits. See 42 U.S.C. § 402(d) (2014); 20 C.F.R. §§ 404.350(a)(1), 404.354 (2014). In relevant
                                          part, the Act defines child as the child or legally adopted child of an individual.
                                          See 42 U.S.C. §§ 402(d)(1); 416(e); 20 C.F.R. §§ 404.350, 404.354; Astrue v. Capato, --- U.S. ---, 132 S. Ct. 2021, 2027-28 (2012). The Act’s definition of child is met if
                                          the applicant is able to inherit from the insured under state law if the insured were
                                          to die without leaving a will. See 42 U.S.C. § 416(h)(2)(A); 20 C.F.R. §§ 404. 355(a)(1), (b); Capato, 132 S. Ct. at 2028. In determining whether an applicant should be considered the
                                          child of an insured individual, the Commissioner applies the law governing intestate
                                          transfers in the state where the insured was domiciled at the time of the child’s
                                          application. See 42 U.S.C. § 416(h)(2)(A). Here, Missouri intestacy law applies because the NH was
                                          domiciled in Missouri at the time of the claimant’s application.

                                       Under Missouri law, a child may inherit if he or she is the issue or child of the
                                          decedent. See Mo. Ann. Stat. § 474.010. The Probate Code defines “issue” or “child” broadly. See Mo. Stat. Ann. § 472.010(2) (“‘Child’ includes an adopted child and a child born
                                          out of wedlock, but does not include a grandchild or other more remote descendants.”);

                                       While the Missouri Probate Code governs determinations of parentage, one may use the
                                          evidentiary standards and presumptions of the common law or the Missouri Uniform Parentage
                                          Act (UPA) in proving parentage. See LeSage v. Dirt Cheap Cigarettes and Beer, Inc., 102 S.W.3d 1, 4 (Mo. 2003) (citing In re Nocita, 914 S.W.2d 358, 359 (Mo. 1996)); Matter of Charles H. Stix Testamentary Trust Dated
                                          August 7, 1945, 2015 WL 1915279, at *2 (Mo. App. E.D. 2015) (“It has long been the
                                          law of this state that a child born during a marriage is legally presumed to be the
                                          husband’s offspring for all purposes, including matters of probate and inheritance.”).
                                          Under Missouri common law, children born in wedlock are presumed to be the legitimate
                                          issue of the marital spouses and are entitled to the rights of support and inheritance.
                                          See In the Matter of Stix, 2015 WL 1915279, at *2; In re: L., 499 S.W.2d 490, 492 (Mo
                                          1973) (en banc) (noting the “ancient presumption that a child born in wedlock is presumed
                                          to be legitimate”); B.S.H. v. J.J.H., 613 S.W.2d 453, 457 (Mo. App. W.D. 1981) (“A

                                          The UPA also provides that children born in wedlock are presumed to be the legitimate
                                          issue of the husband. See Mo. Stat. Ann. § 210.822.

                                       While no Missouri court has considered whether the parentage presumption described
                                          in the common law or the UPA applies to the non-biological parent/spouse in a same-sex
                                          marriage, a Missouri court would likely apply the presumption to the non-birthing
                                          spouse.

                                                   First, such a ruling is consistent with a plain reading of the entire UPA, which provides
                                                      that the UPA provisions relating to the father also apply to the mother. See Mo. Stat. Ann. §§ 210.819(1), (2) (providing that the parent-child relationship for
                                                      the mother or father may be established under the provisions of sections 210.817 to

                                                   Second, applying the presumption to same-sex spouses, as it is applied to opposite-sex
                                                      spouses, serves the “fundamental goal [of] the establishment of ‘uniformity among

                                                   Third, it is consistent with public policy that seeks to secure and promote the welfare
                                                      and support of children. See, e.g., Piel, 918 S.W.2d at 375 (“The purpose of the UPA was to establish a uniform method for

                                                      at https://governor.mo.gov/news/executive-orders/executive-order-15-04 (last visited on Dec. 22, 2015).
                                                   
                                                   
                                                 
                                              
                                           
                                       
                                       
                                       Finally, applying the parentage presumption to the non-birthing same-sex spouse is
                                          consistent with the holdings of other courts who have considered the issue. See Gartner v. Iowa Dep’t of Pub. Health, 830 N.W.2d 335, 353 (Iowa 2013), as amended (May 23, 2013) (finding presumption
                                          of parentage applies to same-sex couple and presumption of parentage statute that
                                          precluded naming non-birthing same-sex spouse on birth certificate violated the Iowa
                                          constitution); Wendy G-M. v. Erin G-M., 985 N.Y.S.2d 845, 848 (Sup. Ct. of Monroe Cty. May 7, 2014) (Under New York common
                                          law, female non-birthing spouse was presumed parent of child conceived by artificial

                                          this court finds that the protections of Connecticut’s common-law presumption of legitimacy
                                          apply equally to children of same-sex and opposite-sex married couples and that the
                                          marital presumption applies equally to same-sex and opposite-sex marriages.”) (citing Hunter v. Rose, 975 N.E.2d 857, 861 (Mass. 2012) (finding the same-sex spouses both to be legal

                                          relationship are presumed to be children of both spouses”) and Miller-Jenkins v. Miller-Jenkins, 912 A.2d 951, 969-71 (Vt. 2006) (finding same-sex couple’s legal union at the time
                                          of the child’s birth is extremely persuasive evidence of joint parentage in that the
                                          presumption of legitimacy applies)); see also Chatterjee v. King, 280 P.3d 283, 289-92 (N.M. 2012) (New Mexico UPA should apply equally to men and

               While the claimant is not the biological child of the NH, the NH’s parentage is presumed
                  as the claimant was born in wedlock between the NH and the mother. The parent-child
                  relationship is also established as the NH is listed as a parent on the claimant’s
                  birth certificate. See Mo. Stat. Ann. § 193.255 (A certified copy of a vital record shall be prima facie
                  evidence of the facts stated therein.). A Missouri court, therefore, would likely
                  find that the claimant is entitled to inherit from the NH under Missouri intestacy
                  law. Under section 416(h)(2)(A) of the Act, the claimant is the NH’s child and deemed
                  dependent. Accordingly, you can find he is entitled to child’s insurance benefits
                  on the NH’s record.
               
               CONCLUSION
               For the reasons outlined above, the claimant would be entitled to benefits on the
                  NH’s record as her child.
