               ISSUE
               Is Buck B~ the legally adopted child of the wage earner and Mrs. B~ for purposes of
                  the child's entitlement to surviving child's insurance benefits?
               
               Facts
               On August 7, 1986 while residing in the Philippines, the wage earner and his wife
                  petitioned the Regional Trial Court, Third Judicial Region, Angeles City, Philippines
                  to adopt the claimant. The claimant is the illegitimate child of the niece of the
                  wage earner's wife.
               
               The claimant's natural mother, a minor at the time, and the claimant's maternal grandmother
                  both consented to the adoption in writing. The identity of the claimant's natural
                  father is unknown. There is no evidence that the written consent to the adoption of
                  this father was obtained.
               
               The wage earner had five natural children from a previous marriage. Three of the children
                  consented in writing to the adoption. The wage earner had lost contact with his other
                  two children and no consent was obtained from them. The wage earner's wife had a child
                  out of wedlock by another man. There is no evidence that written consent to the adoption
                  of this child was obtained.
               
               An adoption decree was issued by the Philippines court on November 28, 1986. A birth
                  certificate was subsequently issued showing the wage earner and his wife as the child's
                  parents. The family moved to the United States on March 13, 1987. The wage earner
                  died March l, 1988. At the time of his death, he and his wife and the claimant resided
                  in Michigan.
               
               Discussion
               Under the Social Security Act the minor child of a currently insured individual is
                  entitled to Social Security benefits, if the child was dependent upon the individual
                  at the time of such individual's death and if the child meets the definition of "child"
                  under the Act. Title II of the Social Security Act § 202(d)(1), 42 U.S.C. § 402(d)(1).
               
               The Act defines a child as "the child or legally adopted child of an individual."
                  42 U.S.C. § 416(e)(1).
               
               In determining whether an applicant is the child or parent of a fully or currently
                  insured individual for purposes of this title, the Secretary shall apply such law
                  as would be applied in determining the devolution of intestate personal property ...,
                  if such insured individual is dead, by the courts of the State in which he was domiciled
                  at the time of his death, .... Applicants who according to such law would have the
                  same status relative to taking in estate personal property as a child or parent shall
                  be deemed such.
               
               42 U.S.C. § 416(h)(2)(A).
               Under the law of Michigan an "adopted person is an heir of the adopting parents ....
                  " MICH. COMP. LAWS §700.110 (1987-1988). Michigan recognizes an adoption of an alien
                  child completed according to the law of the foreign country by the court of the country
                  of the child's nationality. MICH. ATT'Y GEN. lg55-56, No. 1842 at 341 as reported
                  in MICH. COMP. LAWS § 710.1 note 17 (1968). It therefore becomes necessary to determine
                  the validity of claimant's adoption under Philippine Law.
               
               We referred the question of the validity of claimant's adoption in the Philippines
                  to the Library of Congress. The communications with the Library of Congress, including
                  the Library's response, are attached hereto.
               
               Generally under Philippine law the written consent of both natural parents is required
                  for a child to be adopted. However, in the case of an illegitimate and unrecognized
                  child, the consent of the father who abandons the child is not necessary.
               
               Philippine law also requires the written consent to the adoption of natural children
                  of the adopting parents fourteen years of age and older.
               
               Although the written consent of the wage earner's children was necessary and such
                  consent was not obtained from two of his five children, the Library of Congress concluded
                  that Philippine law would excuse such consent where the children had "abandoned" their
                  natural parent.
               
               The consent of the mother's illegitimate child would not be necessary if the child's
                  parents had been disqualified from marrying one another at the time of the child's
                  birth by an impediment. The claims folder does not contain enough information to determine
                  whether this is true.
               
               Regardless, however, of whether all of the legal requirements for adoption in the
                  Philippines were met, the adoption decree is considered valid under Philippine law,
                  unless and until it is invalidated by the appropriate court in the Philippines. Since
                  we have no information that it has been invalidated, the adoption is valid under Philippine
                  law.
               
               Conclusion
               Claimant, being validly adopted under Philippine law, is considered the child of the
                  wage earner for purposes of intestate succession in Michigan. He is therefore the
                  child of the wage earner under Title II of the Social Security Act.
