A claimant may be eligible for CIB on the earnings record of an individual entitled
                  to old-age or disability benefits if the claimant is the insured individual’s “child.”
                  See Social Security Act (Act) § 202(d)(1); 20 C.F.R. § 404.350(a)(1) (2021)[1] Program Operations Manual System (POMS) GN 00306.002A, B; POMS RS 00203.001A.1.b[2] . The regulations define a child as a natural child, legally adopted child, stepchild,
                  grandchild, step-grandchild, or equitably adopted child. See 20 C.F.R. §§ 404.355-359. In order to determine whether a claimant is a legally adopted
                  child, the Social Security Administration applies the adoption laws of the State or
                  the foreign country where the adoption took place. 20 C.F.R. § 404.356; POMS GN 00306.135; GN 00306.155C. To be a legal adoption, the adoption must be valid under the law of the State or
                  foreign country where it took place. See id. Accordingly, Claimant may qualify for benefits as the legally adopted child of the
                  NH, if the adoption was valid under the law of Panama, the foreign country where the
                  adoption took place.
               
               Panama’s Adoption Law provides that a ruling issued in a judicial proceeding is required
                  to establish the filiation relationship created by an adoption. See The Law Library of Congress, Global Legal Research Directorate, LL File No. 2021-020238.
                  The ruling is then sent to Panama’s Civil Registry. See id. For children younger than seven, a new birth certificate is issued with the last
                  name of the adoptive parents. A copy of the new birth certificate may be obtained
                  from the Civil Registry. See id. For confidentiality reasons, the copy does not include specifics regarding the adoption
                  proceedings. See id. However, parties to the adoption proceedings have access to the adoption records
                  if necessary. See id.
               In this case, although Claimant’s birth certificate indicates Claimant has NH’s last
                  name and lists NH as her father, NH does not present proof of a ruling issued in a
                  judicial proceeding that is necessary to establish a Panamanian adoption. Furthermore,
                  because NH was a party to the adoption, he has access to additional Panamanian adoption
                  records. Thus, NH should submit additional evidence showing a judicial proceeding
                  established NH as Claimant’s adopted father.[3]
