You asked whether a child conceived by artificial insemination qualifies for child's
                  insurance benefits as the child of the semen donor or the mother's husband at the
                  time of conception and birth.
               
               PROCEDURAL HISTORY
               On January 19, 2006, Laurie A. A~, a.k.a. Laurie P~ (the claimant's mother) filed
                  an application for child's insurance benefits (life claim) on behalf of Jonathan H.
                  V~ (the claimant) on the account of Bruce B~ (the alleged biological father), her
                  husband from a prior marriage. See January 19, 2006 application. You indicated that the biological father was domiciled
                  in the State of California at the time the application was filed. The application
                  was granted with payments retroactive to September 2005. See Notice of Award.
               
               The claimant's mother, however, was married to another man, Robert V~, at the time
                  of the claimant's conception and birth. See Worksheet Remarks. She had not provided medical evidence that the presumed father
                  was sterile. See
                     id. Thus, on November 22, 2005, the claim on the biological father's account was disallowed
                  on reconsideration. See id. 
               On June 26, 2006, Laurie filed a new application (life claim) on Jonathan's behalf
                  on the account of the presumed father, Robert V~. See Development Worksheet dated June 26, 2006. You indicated that the presumed father
                  was domiciled in the State of Pennsylvania at the time the application was filed.
               
               We consolidated the review of the claimant's successive applications in this opinion.
                  The following is a summary of the evidence presented in support of these applications.
               
               SUMMARY OF EVIDENCE
               Laurie P~ married Robert V~ in Placerville, California. See marriage certificate. They divorced on July 1, 2003 in the State of Nevada. See Decree of Divorce (filed July 1, 2003). Starting in 1991, Laurie underwent a course
                  of artificial insemination in a California clinic "due to her husband's history of
                  vasectomy." Report by L.V. B~, M.D., dated February 25, 1994; see also April 27, 2006 letter from Emerald Bay Center for Women's Health.
               
               The record suggests that Robert was aware of, and consented to the artificial insemination
                  of his wife. There is no written record of his consent because the clinic's policy
                  did not require a husband's consent. See Report of Contact with Practice Manager at Emerald Bay Center for Women's Health on
                  July 6, 2006. There is nonetheless a later record indicating that Laurie was accompanied
                  by Robert for a pregnancy care visit. See July 21, 1995 treatment notes.
               
               In addition, Laurie stated that Robert and the biological father agreed to her artificial
                  insemination with the latter's semen. See Report of Contact of Claimant's mother on October 7, 2005. According to Laurie, the
                  artificial insemination was performed not at the clinic, but at the family's home.
                  See
                     Report of Contact of Claimant's mother on October 7, 2005. Robert and Laurie lived
                  together at the time. See their declarations of March 14 and 28, 2006. On October 19, 1995, Laurie gave birth
                  to Jonathan in California. See Claimant's birth certificate. The birth certificate lists Laurie as the mother and
                  informant, and Robert as the father.  See
                     id. According to Laurie, Robert raised Jonathan as his child during the marriage. See Report of Contact of Claimant's mother on October 7, 2005.
               
               On July 1, 2003, a Nevada court entered a final decree of divorce incorporating the
                  parties' marital settlement agreement. See Property Settlement and Child Custody Agreement (Agreement) and Decree of Divorce
                  (filed July 1, 2003). In the Agreement, they acknowledge the existence of "one minor
                  child the issue of this marriage, to-wit: Jonathan H. V~, born 10/19/95 . . . ." Agreement.
                  The court ordered Robert to pay child support for Jonathan and granted legal custody
                  of Jonathan to both parents. See id. According to Laurie, however, Robert "now since they are no longer married refuses
                  to pay child support." See Report of Contact of Claimant's mother on October 7, 2005.
               
               On or about January 11, 2006, Laurie, Jonathan, Robert, and Bruce were genetically
                  tested. See DNA Parentage Test Report dated January 11, 2006. The results established a 99.99+
                  percent probability that Bruce is Jonathan's biological father. See id. On January 19, 2006, Bruce acknowledged that he is the biological father based on
                  that evidence. See Child Relationship Statement - Bruce B~. He explained, however, that he did not otherwise
                  acknowledge, provide for, or hold out the child as his own. See
                     id.
               In a February 2, 2006 declaration, Robert indicated that he was sterilized in approximately
                  1972, and that Bruce is Jonathan's biological father. See
                     Robert V~'s declaration (February 2, 2006). In a March 28, 2006 declaration, Robert
                  stated that he was unable to provide medical records of his vasectomy. See V~ declaration (March 28, 2006).
               
               ANALYSIS
               A. Federal Law
               We determine a claimant's eligibility for child insurance benefits under section 202(d)(1)
                  of the Social Security Act by determining whether he is the "child" of an insured
                  individual as defined in section 216(e) and was dependent on the insured under section
                  202(d)(3). See Social Security Act § 202(d)(1); 20 C.F.R. § 404.350 (2006). In cases where parentage
                  is in dispute or the child is illegitimate, section 216(h) remains the appropriate
                  analytical framework for determining "child" status under section 216(e). See Gillett-Netting v.
                     Barnhart, 371 F.3d 593, 596-97 (9th Cir. 2004) (holding that parentage need not be established
                  under § 216(h) unless parentage is in dispute or the child is illegitimate); see also Acquiescence Ruling (AR) 05 1(9), 70 Fed. Reg. 55,656 (September 22, 2005).
               
               Section 216(h)(2)(A) directs us to "apply such law as would be applied in determining
                  the devolution of intestate personal property by the courts of the State in which
                  such insured individual is domiciled . . . at the time the application was filed .
                  . . ." Social Security Act § 216(h)(2)(A). We would apply California law to the claimant's
                  January 19, 2006 application on the account of his alleged biological father who was
                  domiciled in California at that time. If we find that that application was properly
                  denied, we would apply Pennsylvania law to the claimant's June 26, 2006 application
                  on the account of his presumed father who was domiciled in Pennsylvania.
               
               B. California Intestacy Laws and Claimant's Application on the Account of his Alleged
                  Biological Father, Bruce B~
               
               Under California intestacy law, a child may inherit the intestate estate of his natural
                  parent. Cal. Prob. Code §§ 6401, 6402, 6450 (2006). A natural parent and child relationship
                  for purposes of intestate succession may be established based on a "presumed father"
                  status under the Uniform Parentage Act (Cal. Fam. Code § 7600, et seq.). Cal. Prob.
                  Code § 6453. A man who was neither legally married nor attempted to legally marry
                  the mother of his child cannot, however, be a "presumed father" unless he receives
                  the child into his home and openly holds out the child as his natural child. Cal.
                  Fam. Code § 7611(d). Further, a "donor" who provided semen for use in the artificial
                  insemination of a woman other than his wife through a physician has no valid paternity
                  claim. See Cal. Fam. Code § 7613(b).
               
               Here, even if Bruce's semen was used, he was only a "donor," and never attained "presumed
                  father" status. See id. Notwithstanding the fact that Bruce may have been Laurie's husband by a prior marriage,
                  he was not married or attempted to marry her at any relevant time, and had no relationship
                  with the claimant. See Cal. Fam. Code § 7611. There is no indication that he attempted to create a relationship
                  with the claimant either before or after Laurie's divorce from Robert.  See id. 
               As further consideration, California law would not recognize Bruce's biological paternity
                  since he had not taken the child into his home nor developed a parent-child relationship;
                  on the other hand, the claimant's longstanding father-child relationship with Robert,
                  his presumed father militates against the existence of presumed or natural father
                  status with Bruce. For more than seven years after the child's birth, Robert assumed
                  the obligations and functions characteristic of a father-child relationship.  See, e.g., Agreement; and Cal. Fam. Code § 7611(d) (presumed father status based on actual
                  parenting). The existence of a longstanding relationship provides the strongest policy
                  consideration for preserving Robert's status in this case. See
                     Guardianship of Claralyn S., 148 Cal. App. 3d 81, 86 (1983) ("in the case of an older child the familial relationship
                  between the child and the man purporting to be the child's father is considerably
                  more palpable than the biological relationship of actual paternity") (internal quotes
                  and citation omitted). In addition, the claimant was born during Robert and Laurie's
                  marriage. See Cal. Fam. Code § 7611(a) (husband presumed father of child born in wedlock).
               
               That the presumed father Robert belatedly disclaimed paternity is of no consequence
                  to his status. As the California Supreme Court reasoned in a leading case:
               
               [o)ne who consents to the production of a child cannot create a temporary relation
                  to be assumed and disclaimed at will, but the arrangement must be of such character
                  as to impose an obligation of supporting those for whose existence he is directly
                  responsible.
               
               People v. Sorenson, 68 Cal. 2d 280, 285 (1968). In Sorenson, the California Supreme Court held the father criminally liable for unpaid child
                  support for a child who was not genetically related to him, when he consented to the
                  procreation of the child through artificial insemination of his wife by an anonymous
                  sperm donor. Based in part on the decision in Sorenson and other case law cited therein, we advised that a husband who had consented to artificial
                  insemination of his wife was the legal father of the child, even though the father
                  and mother separated before the child was born, and the biological father never had
                  any contact with the child. See POMS PR 01105.006.A, Claim for Child Insurance
                     Benefits on account of wage earner, Joseph B~ (September 24, 2003).
               
               Here, the presumed father Robert took Jonathan into his home and raised him as his
                  own for seven years. Thus, even if Robert later chose to have his DNA tested to disclaim
                  paternity, such evidence would not be admissible because he consented to the claimant's
                  conception by artificial insemination and assumed the obligations of a father for
                  seven years.  See Cal. Fam. Code § 7541(e).
               
               Finally, the Nevada stipulated court order would be given full faith and credit by
                  courts and have the same effect as a paternity determination made in California. See Cal. Fam. Code § 5604. The order would be binding on the parties and their privies.
                  See Guardianship of Claralyn S., 148 Cal. App. 3d 81, 85 (1983). In addition, Cal. Fam. Code § 7630(a)(2) would require
                  that an action to declare the nonexistence of a presumed parent and child relationship
                  be "brought within a reasonable time." Cal. Fam. Code § 7630(a)(2). The statute reflects
                  the strong California public policies of maintaining established parent-child relationships
                  and ensuring the finality of paternity judgments, which go beyond the doctrines of
                  res judicata and collateral estoppel. See
                     Guardianship of Claralyn S., 148 Cal. App. 3d at 85 (applying policy to preclude a challenge brought by grandparents
                  who were not parties to the action in which the parentage finding was made). There
                  is no likelihood that a court would entertain a challenge to the presumed father's
                  paternity of a child born, like the claimant, over 10 years ago. Finally, it is unlikely
                  that the claimant could show that his best interest requires disregarding a longstanding
                  father-child relationship.
               
               As the foregoing analysis indicates, the court's determination appears to be fair
                  and correct under California law, and is not the result of a judgment by defA~. There
                  is no reason why it should be disturbed by the Agency. See Gray v.
                     Richardson, 474 F.2d 1370, 1372 (6th Cir. 1973) (Agency is not free to ignore the adjudication
                  of a state trial court in a contested proceedings where it is fair and consistent
                  with the law as enunciated by the highest court of the State); see also SSR 83-37c, http://www.socialsecurity.gov/OP_Home/rulings/oasi/09/SSR83-37-oasi-09.html (adopting that circuit court decision), and Memorandum from Regional Chief Counsel,
                  San Francisco, to Ass't Reg. Comm.-MOS, Richmond, Claim for Child's
                     Insurance Benefits on Account of Wage Earner Michael Phillip Ferrel,
                     Jr. (August 22, 2005) (reprinted in POMS PR 01215.006).
               
               In light of the foregoing, we believe that the claimant's application for child's
                  insurance benefits on the account of Bruce B~ was properly disallowed on reconsideration.
                  We thus turn to the claimant's application on the account of his presumed father in
                  light of Pennsylvania intestacy laws.
               
               C. Pennsylvania Intestacy Laws and Claimant's Application on the Account of his Presumed
                  Father, Robert V~
               
               Pennsylvania law vests intestate inheritance rights in "the issue of the decedent."
                  20 Pa. C.S. § 2103 (2006). As to the determination of Jonathan's paternity, Pennsylvania
                  law relies on the same policy considerations as California. As indicated below, these
                  considerations lead us to conclude that Robert is the claimant's father.
               
               Specifically, Robert is presumed to be the legitimate father of the claimant as a
                  child of the marriage. Miscovich v. Miscovich, 688 A.2d 726, 728-29 (Pa. Super. Ct. 1997). "Although the presumption is rebuttable,
                  one who attempts to overcome it bears a heavy burden." Id.
               Even if the presumption could be successfully overcome, Robert would be estopped from
                  denying paternity because he consented to the artificial insemination, supported Jonathan
                  as his own for more than seven years, agreed to do so in a marital settlement agreement,
                  and did not appeal the court's support order. See, e.g., McConnell v.
                     Berkheimer, 781 A.2d 206, 211 (Pa. Super. Ct. 2001) (applying estoppel doctrine where, in particular,
                  father lived with the mother and the child for four months after the child's birth,
                  accepted the child as his own for over a year; and failed to timely appeal support
                  and contempt order); Miscovich, 688 A.2d at 726 (denying husband's request for blood tests to disprove paternity
                  where husband had an established relationship with child that did not deteriorate
                  until after relationship with wife deteriorated, a familial relationship existed at
                  the time the child was born, and no evidence of nonaccess, sterility, or impotency
                  was offered); Commonwealth ex rel. Gonzalez v. Andreas, 369 A.2d 416, 418 (Pa. Super. Ct. 1976) (same where, for approximately three years,
                  parties lived together following the child's birth and father supported the child
                  as his own and never expressed any doubts about the child's parentage).
               
               That the alleged biological father belatedly acknowledged paternity is of no consequence.
                  As previously indicated and as opposed to Robert's conduct, Bruce has not played any
                  significant role in the child life. As a result, he would be estopped from asserting
                  paternity. See Buccieri v. Campagna, 889 A.2d 1220, 1228 (Pa. Super. Ct. 2005) (finding that delay and inactivity for
                  eight years barred alleged biological father from asserting paternity where mother's
                  husband was involved in child parenting for three years).
               
               Finally, the Nevada court's July 1, 2003 final order would be given full faith and
                  credit by Pennsylvania courts and have the same effect as a paternity determination
                  made in Pennsylvania. See Chrzanowski v. Chrzanowski, 472 A.2d 1128, 1131 (Pa. Super. Ct. 1984). Because Robert was afforded the opportunity
                  to litigate, he would be barred from relitigating the issue of his paternity that
                  was determined by a court of competent jurisdiction. See Ruth F. v. Robert
                     B., 690 A.2d 1171, 1174-75 (Pa. Super. Ct. 1997) ("Principles of res judicata are also
                  applicable to determinations of paternity."). Again, the Agency is not free to disregard
                  the court order, which appears to be fair and correct.
               
               In sum, we believe that the claimant's application for child's insurance benefits
                  on the account of Robert V~ should be granted.
