A. Federal Law: Entitlement to Surviving Child’s Insurance Benefits under the
                        Act as a “Child” Per Section 216(h)(2)(A)
               Under Title II of the Act, a claimant may be entitled to child’s insurance benefits
                  on an insured number holder’s account if, among other things, he or she is the insured
                  number holder’s child.[3] See 42 U.S.C. § 402(d)(1); 20 C.F.R. § 404.350. The Act and regulations define “child”
                  as an insured number holder’s natural child, legally adopted child, stepchild, grandchild,
                  step grandchild, or equitably adopted child. See 42 U.S.C. § 416(e); 20 C.F.R. §§ 404.354˗.359; POMS GN 00306.002. Consistent with the evidence provided, our inquiry focuses on whether the Claimant
                  is the NH’s natural child.
               
               To determine a claimant’s status as a natural child, the agency must determine whether
                  the claimant could inherit the insured number holder’s personal property as his child
                  under the intestacy laws of the State where the insured number holder had his permanent
                  home at the time of his death. See 42 U.S.C. § 416(h)(2)(A); 20 C.F.R. § 404.355(a)(1), (b); POMS GN 00306.010. We are unaware of any legal authority requiring the agency to apply a different
                  standard under the Act for determining whether a claimant is a number holder’s natural
                  child when the claimant or the number holder is a member of an Indian tribe (i.e.,
                  applying tribal law instead of the intestate succession law of the State where the
                  number holder was domiciled).
                     See 42 U.S.C. § 416(h)(2)(A); 20 C.F.R. § 404.355(a)(1), (b). Thus, per the Act and regulations
                  and consistent with published legal opinions on the issue from our office and others,
                  we begin the analysis of whether the Claimant is the NH’s natural child by looking
                  to State intestate succession law. See e.g., POMS PR 01115.004 Arizona, A. PR 19-200 (Sept. 26, 2019) (applying Arizona intestacy law to evidence
                  that included a Navajo Family Court order establishing paternity to determine if the
                  claimant is the number holder’s child under section 216(h)(2)(A) of the Act); POMS
                  PR 01115.029 Montana, A. PR 06-009 (Nov. 14, 2005) (applying Montana intestacy law to evidence
                  that included Blackfeet Tribe enrollment documents and an amended Montana birth certificate
                  to determine if the claimant is the number holder’s child under section 216(h)(2)(A)
                  of the Act); POMS PR 01115.034 New Mexico, D. PR 03-085 (Jan. 27, 2003) (applying New Mexico intestacy law to evidence
                  that included a Navajo Nation paternity decree and a New Mexico birth certificate
                  to determine if the claimant is the number holder’s child under section 216(h)(2)(A)
                  of the Act).[4]
               Oklahoma law controls because the NH’s permanent home was in Oklahoma when he died.
                  Therefore, we apply Oklahoma intestate succession laws to determine whether the Claimant
                  could inherit from the NH as his child.
               
               1. Oklahoma Intestate Succession Law and a Child’s Right to Inherit
               Oklahoma law allows a child to inherit property from her deceased parent by intestate
                  succession. See Okla. Stat. Ann. tit. 84, §§ 213, 215 (allowing a child to inherit property by intestate
                  succession, and stating that a child born out of wedlock may inherit from her purported
                  father in the same way as a child born in wedlock if one of four requirements is met).
                  However, it provides different standards for children born within marriage and out
                  of marriage to establish a parent-child relationship for inheritance purposes.
               
               For a child born into a marriage, Oklahoma law creates a presumption of paternity
                  to establish a parent-child relationship for inheritance purposes. See In re Estate of Dicksion, 286 P.3d 283, 288-291 (Okla. 2012) (the paternity statute applied to intestate
                  and probate proceedings); Okla. Stat. Ann. tit. 10, § 7700-203 (a parent-child relationship
                  established under the Uniform Parentage Act applies for all purposes). The presumption
                  does not apply in this case because there is no claim or evidence of a marriage between
                  the Claimant’s mother and the NH.
               
               For a child born outside of a marriage, Oklahoma law requires the child to provide
                  proof of the child’s relationship to the father in order to inherit from that father
                  under Oklahoma intestate succession law. See Okla. Stat. Ann. tit. 84, § 215; see also In re Estate
                     of Watson, 135 P.3d 853, 855 (Okla. Civ. App. 2006) (citing Frazier v.
                     McCary, 236 P. 880 (Okla. 1925)). A child born out of a marriage must satisfy one of the
                  following four methods to establish inheritance rights from a purported father:
               
               (a) the father, in writing and signed in the presence of a competent witness, acknowledges
                  himself to be the child’s father,
               
               (b) the father and mother intermarry after the child’s birth, and the father, after
                  such marriage, acknowledges the child as his own or adopts her into his family,
               
               (c) the father publicly acknowledges such child as his own, receiving her as such,
                  with the consent of his wife, if he is married, into his family and otherwise treating
                  her as if she were a child born in wedlock, or
               
               (d) the father is judicially determined to be such in a paternity proceeding before
                  a court of competent jurisdiction.
               
               See Okla. Stat. Ann. tit. 84, § 215.
               
               Here, there is no evidence that the NH acknowledged the Claimant as his child in writing
                  in the presence of a competent witness; no claim or proof of a marriage between the
                  Claimant’s mother and the NH either before or after the Claimant’s birth; and no evidence
                  that the NH publicly acknowledged the Claimant as his own child and otherwise treated
                  her as his child. Thus, the first three methods for establishing a father-child relationship
                  are inapplicable here. See Okla. Stat. Ann. tit. 84, § 215(a)-(c). The final method for establishing a father-child
                  relationship under Oklahoma law requires a judicial determination of paternity in
                  a paternity proceeding from a court of competent jurisdiction. See Okla. Stat. Ann. tit. 84, § 215(d). We consider whether the Kickapoo Tribe of Oklahoma
                  court documents satisfy this method for establishing a father-child relationship that
                  would allow the Claimant the right to inherit from the NH.
               
               2. The Law Provides Generally that an Indian Tribal Court is a Court of Competent
                     Jurisdiction for Parent-Child Proceedings and Tribal Court Judgments are Entitled
                     to Full Faith and
                     Credit 
               We believe generally that a paternity determination from the Kickapoo Tribe of Oklahoma[5] District Court would be considered a judicial determination from a court of competent
                  jurisdiction for purposes of Okla. Stat. Ann. tit. 84, § 215(d). Federal law recognizes
                  the jurisdiction and authority of tribal courts over various domestic relations issue.
                  See
                     e.g., IWCA, 25 U.S.C. § 1911(a) (providing that a tribal court has exclusive jurisdiction
                  over a child custody proceeding of “an Indian child who resides or is domiciled within
                  the reservation of such tribe,” or is a ward of a tribal court); National Farmers Union Ins.
                     Companies v. Crow Tribe of Indians, 471 US 845, 856 (1985) (“Our cases have often recognized that Congress is committed
                  to a policy of supporting tribal self-government and self-determination.”); Montana v. U.S., 450 U.S. 544, 564 (1981) (noting that “the Indian tribes retain their inherent power
                  to determine tribal membership, to regulate domestic relations among members, and
                  to prescribe rules of inheritance for members,” but also noting that such power did
                  not extent to relations between an Indian tribe and non-members of the tribe); Nat’l Labor Relations Bd. v. Little River Band of Ottawa Indians Tribal Gov’t, 788 F.3d 537, 544 (6th Cir. 2015) (“Indian tribes retain broad residual power over
                  intramural affairs: they may determine tribal membership, regulate domestic relations
                  among members, prescribe rules of inheritance among members, and punish tribal offenders.”).
               
               In addition, under the Kickapoo Tribe of Oklahoma Child Support Code, the Kickapoo
                  Tribe of Oklahoma District Court appears to have jurisdiction over proceedings concerning
                  any action to determine and establish child support – which would appear to also include
                  proceedings to establish paternity – and jurisdiction over any person who is a member
                  of the Kickapoo Tribe, any minor who is eligible to be a member of the Kickapoo Tribe,
                  or any person who is alleged to be the parent of a “Kickapoo child”[6] residing within the Kickapoo Tribe’s jurisdiction. See Kickapoo Tribe of Oklahoma Child Support Code, Chapter 1, Section 3.[7] Further, the Kickapoo Tribe of Oklahoma Child Support Code specifically allows a
                  child, the child’s natural mother, or an alleged father of a child to file a petition
                  requesting the Kickapoo Tribe of Oklahoma Tribal Court[8] to establish paternity in a paternity proceeding. See id., Chapter 5, Section 2(A). Thus, both Federal and tribal law generally supports the
                  Kickapoo Tribe of Oklahoma District Court’s jurisdiction over a paternity proceeding
                  involving a Kickapoo child.
               
               Moreover, under Oklahoma law, an Oklahoma State court would be required to provide
                  full faith and credit to a judicial determination from a tribal court – in this case
                  the Kickapoo Tribe of Oklahoma District Court – based on the rule of mutual reciprocity
                  set forth in both Oklahoma law and Kickapoo tribal law. See Okla. Stat. Ann. tit. 12, Ch. 2, Rule 30 (requiring district courts for the State
                  of Oklahoma to “grant full faith and credit and cause to be enforced any tribal judgment
                  where the tribal court that issued the judgment grants reciprocity to judgments of
                  the courts of the State of Oklahoma . . .”); Okla. Stat. Ann. tit. 12, § 728 (“This
                  Act affirms the power of the Supreme Court of the State of Oklahoma to issue standards
                  for extending full faith and credit to the records and judicial proceedings of any
                  court of any federally recognized Indian nation, tribe, band or political subdivision
                  thereof, including courts of Indian offenses. . . In issuing any such standard the
                  Supreme Court of the State of Oklahoma may extend such recognition in whole or in
                  part to such type or types of judgments of the tribal courts as it deems appropriate
                  where tribal courts agree to grant reciprocity of judgments of the courts of the State
                  of Oklahoma in such tribal courts.”); Barrett v. Barrett, 878 P.2d 1051, 1054 (Okla. 1994) (discussing this statute and rule in holding that
                  tribal court judgments were entitled to full faith and credit in Oklahoma courts when
                  they granted reciprocity to the judgments of the State of Oklahoma); In re Adoption of Standards for Recognition of Judicial Proceedings of Other
                     Sovereigns in the Courts of the Kickapoo Tribe of Oklahoma: Full Faith & Credit, No. AD-94-101, 6 Okla. Trib. 223, 1994 WL 16006119 (Kickapoo Dec. 5, 1994) (providing
                  that Kickapoo courts will grant full faith and credit to such judgments of federal,
                  state, and other tribal courts provided that the federal, state, or other tribal court
                  grants reciprocity to judgment of Kickapoo courts).
               
               Thus, we believe that generally an Oklahoma State court would give full faith and
                  credit to a paternity determination of the Kickapoo Tribe of Oklahoma District Court
                  as a judgment from a court of competent jurisdiction for purposes of Okla. Stat. Ann.
                  tit. 84, § 215(d). We turn next to the specific tribal court documents provided.
               
               3. Application of the Law to the Facts: The Tribal Court Documents are Insufficient
                     to
                     Determine if the Kickapoo Tribe of Oklahoma District Court had Jurisdiction over the
                     Claimant and
                     the NH, and if the Court Made a Judicial Determination of Paternity as to the NH and
                     the Claimant
                     
               As explained above and given the evidence provided, to establish a father-child relationship
                  for inheritance, Oklahoma law requires a judicial determination of paternity in a
                  paternity proceeding from a court of competent jurisdiction. See Okla. Stat. Ann. tit. 84, § 215(d). As discussed, the Kickapoo Tribe of Oklahoma
                  District Court has jurisdiction over any person who is a member of the Kickapoo Tribe,
                  any minor who is eligible to be a member of the Kickapoo Tribe, or any person who
                  is alleged to be the parent of a “Kickapoo child” residing within the Kickapoo Tribe’s
                  jurisdiction. See Kickapoo Tribe of Oklahoma Child Support Code, Chapter 1, Section 3. While the evidence
                  indicates that the Claimant and the Claimant’s mother are enrolled members of the
                  Kickapoo Tribe, there is no information regarding the Claimant’s residence or domicile
                  within the Kickapoo Tribe’s reservation. Thus, there is insufficient information to
                  determine that the Kickapoo Tribe of Oklahoma District Court had jurisdiction over
                  a paternity proceeding involving the Claimant and the NH.
               
               In addition, the evidence in the record appears insufficient to meet the remaining
                  requirements for establishing paternity under Okla. Stat. Ann. tit. 84, § 215(d).
                  Specifically, the record does not contain evidence indicating that the Kickapoo Tribe
                  of Oklahoma District Court presided over a paternity proceeding involving the Claimant
                  and the NH. See Okla. Stat. Ann. tit. 84, § 215(d). In order to establish paternity through court
                  order in a paternity proceeding, the petitioner must file a petition requesting the
                  Kickapoo Tribe of Oklahoma Tribal Court to establish paternity. See The Kickapoo Tribe of Oklahoma Child Support Code, Chapter 5, Section 2(A). The petition
                  must be duly verified by the party alleging paternity and state the facts to support
                  paternity. See id. The proceedings must be entitled in the name of the Kickapoo Tribe of Oklahoma against
                  the accused as defendant. See
                     id. Here, the petition dated February 2010 does not appear to be a petition of paternity,
                  but a petition for permanent custody and child support filed by the Claimant’s mother
                  against the NH. The petition names the Claimant’s mother as the plaintiff and the
                  NH as the defendant, and requests the court to issue an order granting permanent custody
                  and child support. It does not request the court to enter an order determining the
                  Claimant’s paternity. Nor does it state any facts to support a parent-child relationship
                  between the Claimant and the NH. Thus, it does not appear that there was a paternity
                  proceeding to establish a parent-child relationship between the Claimant and the NH
                  as required by Okla. Stat. Ann. tit. 84, § 215(d) to establish paternity.
               
               Even assuming there was a paternity proceeding, there is no evidence that the Kickapoo
                  Tribe of Oklahoma District Court made a judicial determination regarding the Claimant’s
                  paternity. An order determining paternity from the Kickapoo Tribe of Oklahoma Tribal
                  Court must contain provisions concerning adjudication of parentage, determination
                  of current child support owed as well as determination of arrears and payments thereon,
                  medical insurance coverage, child care costs, income assignments, enforcements, and
                  costs, including genetic testing and any payments for it. See
                     The Kickapoo Tribe of Oklahoma Child Support Code, Chapter 5, Section 3(C). Here,
                  the Kickapoo Tribe of Oklahoma District Court Minute dated March 2010 does not appear
                  to contain the provisions required in an order determining paternity. See id. In its Court Minute dated March 2010, the Kickapoo Tribe of Oklahoma District Court
                  merely ordered as follows: “Custody is awarded to plaintiff. Visitation is reserved.
                  Plaintiff is to make application for Defendant’s SSI benefits. Payee is to assist
                  in getting SSI benefits for minor child.” The Court did not find the NH to be the
                  Claimant’s father. Nor did the Court order the NH to pay child support for the Claimant.
                  If there was a prior determination of paternity made by this same tribal court, the
                  Claimant has not provided this evidence and indeed indicated that no such determination
                  exists. In the Child Relationship Statement that she completed for the agency in January
                  2019, the Claimant’s mother checked a box indicating that no court ever decreed the
                  NH to be the Claimant’s parent or ordered him to contribute to the Claimant’s support.
               
               Thus, we believe an Oklahoma court would find that the Kickapoo Tribe of Oklahoma
                  District Court in the Court Minute issued on March XX, 2010 did not judicially determine
                  the NH to be the Claimant’s father. As such, the agency can reasonably conclude that
                  the Claimant, through the Court Minute and corresponding Petition for Custody and
                  Child Support, has not established a father-child relationship under Okla. Stat. Ann.
                  tit. 84, § 215(d) by showing that a court of competent jurisdiction determined her
                  to be the NH’s child in a paternity proceeding.
               
               4. In the Absence of a Court Determination of Paternity, SSA Decides Paternity Using
                     the
                     Applicable State’s Standard of Proof for Paternity Determinations 
               Even in the absence of a court determination of parentage, SSA will decide parentage
                  using the standard of proof that the state court would use in determining paternity.
                  See 20 C.F.R. § 404.355(b)(1) (the agency will apply the intestacy laws of the State
                  in which the number holder had her permanent home at the time of her death to determine
                  whether an applicant is a number holder’s natural child), (2) (if applicable State
                  inheritance law requires a court determination of paternity, we will not require that
                  you obtain such a determination but will decide your paternity by using the standard
                  of proof that the State court would use as the basis for a determination of paternity).
                  Thus, we look to the totality of the evidence provided to determine if the Claimant
                  has a right to inherit from the NH under Oklahoma law using the standard of proof
                  that an Oklahoma state court would employ.
               
               The Oklahoma Uniform Parentage Act (UPA)[9] applies to parental determinations in intestate and probate proceedings. In re
                     Estate of Dicksion, 286 P.3d 283, 290 (Okla. 2012). The UPA governs every determination of parentage
                  in Oklahoma. Okla. Stat. Ann. tit. 10, § 7700-103(A). Under the UPA, a man may establish
                  a father-child relationship through an adjudication of paternity. See Okla. Stat. Ann. tit. 10, § 7700-201(B)(3).[10] As we have discussed, in the absence of an adjudication of paternity in the present
                  claim, the agency applies the standard of proof an Oklahoma court would apply. See 20 C.F.R. § 404.355(b)(1). Courts consider genetic testing and other evidence to
                  adjudicate the issue of paternity for a child that does not have a presumed, acknowledged,
                  or adjudicated father, which we understand to be the case here with the Claimant.
                  See Okla. Stat. Ann. tit. 10, § 7700-631. Under Oklahoma law, the standard of proof to
                  prove paternity is “clear and convincing evidence.” See In re Estate of King, 837 P.2d 463, 464 (Okla. 1990) (overruled on other grounds); see also Kickapoo Tribe of Oklahoma Child Support Code, Chapter 5, Section 2(F) (the petitioner
                  in a paternity proceeding “has the burden of proving, by clear and convincing evidence,
                  that the putative father is, in fact, the natural father.”). Oklahoma courts define
                  “clear and convincing evidence” as “that measure or degree of proof which will produce
                  in the mind of the trier of fact a firm belief or conviction as to the truth of the
                  allegation sought to be established.” In re A.L.F., 237 P.3d 217, 219 (Okla. 2010). Thus, in this case, an Oklahoma court would look
                  to whether the Claimant has established by clear and convincing evidence that the
                  NH is her father.
               
               Here, there is some evidence that weighs in favor of a parent-child relationship between
                  the Claimant and the NH. A notice from a housing authority dated March 2008, shows
                  that the Claimant’s mother and the NH were members of the same household, and were
                  presumably living together eight months before the Claimant was born in November 2008.
                  Further, the Petition for Custody and Child Support establishes that in February 2010,
                  the Claimant’s mother filed a petition against the NH in a tribal court to grant permanent
                  custody and child support as to the Claimant indicating she was at least alleging
                  that the NH was the Claimant’s father. The Court Minute entered in March 2010 appears
                  to show that the tribal court ordered the Claimant’s mother to file for Social Security
                  benefits for the Claimant on the NH’s record, though this is not entirely clear as
                  the tribal court references Supplemental Security Income (SSI) under Title XVI of
                  the Act, as opposed to auxiliary child’s benefits on the NH’s record under Title II
                  of the Act. Finally, the Claimant’s mother has made statements indicating that the
                  NH acknowledged the Claimant to be his child in a letter to the Claimant’s mother,
                  and acknowledged the Claimant as his child orally to his best friend.
               
               However, there is no corroborating evidence to support the Claimant’s mother’s self-serving
                  statements that the NH acknowledged the Claimant as his child orally or in writing.
                  Likewise, while there is evidence that she petitioned the court for permanent custody
                  and child support, the Claimant’s mother did not provide any facts in her petition
                  to support the NH’s paternity as to the Claimant. The Court Minute only orders the
                  Claimant’s mother to apply for Social Security benefits and orders the “payee” to
                  assist in getting SSI benefits for the minor child. See The Kickapoo Tribe of Oklahoma Child Support Code, Chapter 2, Definitions (“payee”
                  is person in whose name child support is paid). The Court Minute did not make a specific
                  determination that the NH was the Claimant’s father and did not meet the requirements
                  for a paternity determination as set forth in the Kickapoo Court of Oklahoma Child
                  Support Code. See Okla. Stat. Ann. tit. 10, § 7700-636 (providing that the court shall issue an order
                  adjudicating whether a man is the child’s parent and the order adjudicating parentage
                  shall identify the child by name and date of birth); The Kickapoo Tribe of Oklahoma
                  Child Support Code, Chapter 5, Section 3(C) (setting forth the provisions to be included
                  in paternity orders). There is no reference to the NH as a father or parent in the
                  Court Minute. And the Claimant’s mother represented to the agency in the Child Relationship
                  Statement that no court ever decreed the NH to be the Claimant’s parent or ordered
                  him to contribute to the Claimant’s support. She said she did not have any other written
                  evidence of any kind that would show that the Claimant is the NH’s child. She indicated
                  on this form that the NH did not undertake any actions with regard to the Claimant
                  from the time of the Claimant’s birth in November 2008 until the time of the NH’s
                  death in June 2011 that would indicate a parent-child relationship. She has not offered
                  any other witness statements to corroborate the alleged parent-child relationship
                  between the NH and the Claimant. There is no genetic testing evidence. In addition,
                  the Claimant’s birth certificate did not list the NH as her father. Moreover, while
                  the NH filed for disability benefits in December 2008 (the month following the Claimant’s
                  birth) and listed three dependent children for auxiliary benefits, he did not name
                  the Claimant as his dependent child.
               
               In weighing the totality of the evidence provided on the Claimant’s behalf, while
                  there is some evidence to support paternity, we believe an Oklahoma court would find
                  that it is not such that it “will produce in the mind of the trier of fact a firm
                  belief or conviction as to the truth of the allegation sought to be established.”
                  See In re A.L.F., 237 P.3d at 219. Thus, we believe an Oklahoma court would find that the evidence
                  was not clear and convincing evidence to establish a father-child relationship between
                  the NH and the Claimant. See Kinney o/b/o
                     Kinney v. Sullivan, 746 F. Supp. 1067, 1069-71 (W.D. Okla. 1990) (affirming a Social Security administrative
                  law judge’s decision that there was no clear and convincing evidence of paternity).[11] As such, we believe an Oklahoma court would find that the Claimant has not proven
                  the right to inherit from the NH under intestate succession law. See Okla. Stat. Ann. tit. 84, § 215(d). Thus, the agency can reasonably conclude that
                  the Claimant would not be considered the NH’s natural child under section 216(h)(2)(A)
                  of the Act upon application of Oklahoma intestate succession law.
               
               B. Federal Law: Entitlement to Surviving Child’s Insurance Benefits as a
                        “Child” under Section 216(h)(2)(B) and (h)(3)(C) of the Act 
               Having established that the Claimant is unable to establish a parent-child relationship
                  with the NH under section 216(h)(2)(A) of the Act, we also consider whether the Claimant
                  has established the parent-child relationship with the NH under federal standards.
                  See POMS GN 00306.100(A) (“Apply section 216(h)(3) when you cannot establish the parent-child relationship
                  under State law. You may explore all possible relationship provisions consecutively
                  or concurrently.”). Under section 216(h)(2)(B) of the Act, a claimant will be deemed
                  to be a number holder’s child if the claimant is the number holder’s biological child,
                  and the claimant’s parents went through a marriage ceremony that would have been valid
                  but for a legal impediment. See 42 U.S.C. § 416(h)(2)(B); 20 C.F.R. § 404.355(a)(2); POMS GN 00306.090. As there is no indication that the NH and the Claimant’s mother ever married or
                  attempted to marry, this provision does not apply to establish the parent-child relationship.
               
               Under section 216(h)(3)(C)(i) of the Act, the biological child of a deceased number
                  holder may be deemed to be the number holder’s child if, before the deceased number
                  holder’s death: (1) the number holder acknowledged in writing that the child was his
                  child; (2) a court decreed the number holder to be the child’s father; or (3) a court
                  ordered the number holder to contribute to the child’s support. See 42 U.S.C. § 416(h)(3)(C)(i); 20 C.F.R. § 404.355(a)(3)-(4); POMS GN 00306.100. Here, there is no evidence of a written acknowledgment of the Claimant. The Claimant’s
                  mother represented to the agency in the Child Relationship Statement that no court
                  ever decreed the NH to be the Claimant’s parent or ordered him to contribute to the
                  Claimant’s support. As detailed in the prior discussion above with regard to the Court
                  Minute, because there is no evidence of a court order entered before the NH’s death
                  decreeing the NH to be the Claimant’s father or ordering him to pay child support,
                  this provision does not apply to establish the parent-child relationship.
               
               In addition, under section 216(h)(3)(C)(ii) of the Act, a biological child of a deceased
                  number holder may be deemed to be the number holder’s child if the agency finds “by
                  other satisfactory evidence” that the number holder was the child’s biological father,
                  and the number holder was living with or contributing to the child’s support at the
                  time of his death (or if the child was in the womb when the number holder died, the
                  number holder must have been either living with or contributing to the support of
                  the mother at the time of the number holder’s death). See 42 U.S.C. § 416(h)(3)(C)(ii); 20 C.F.R. § 404.355(a)(4); POMS GN 00306.100(C)(3), GN 00306.125. Here, there is no evidence as to whether the NH was living with or contributing
                  to the support of the Claimant (who was born in 2008) at the time of the NH’s death
                  in 2011. Therefore, this provision does not apply to establish the parent-child relationship.
               
               Furthermore, based on the information we have been given, it would appear that the
                  Claimant has not provided sufficient evidence of a biological relationship with the
                  NH, which is required for all of the above standards under section 216(h)(2)(B) and
                  (h)(3) of the Act. See POMS GN 00306.090, GN 00306.100.
               
               Therefore, under the specific evidence provided with this claim, we believe there
                  is legal support for the agency to conclude that the Claimant does not meet the criteria
                  of section 216(h)(2)(B) or (h)(C) of the Act and thus, has not established a parent-child
                  relationship with the NH as required for child’s insurance benefits on the NH’s record.
