Oklahoma statutory law requires that a certificate of birth for each live birth which
                        occurs in the state shall be filed with the State Registrar of Vital Statistics, within
                        seven days after the birth.  Okla. Stat. Ann. tit. 63, § 1-311(A) (West 2024).  If
                        the mother was not married at the time of the birth, nor at any time during the 300
                        calendar days before the birth, the name of the father must be entered on the birth
                        certificate only if:
                     
                     (a) a determination of paternity has been made by an administrative action through
                        the Department of Human Services or a court of competent jurisdiction, in which case
                        the name of the father shall be entered,[5] or
                     
                     (b) the mother and father have agreed as to the biological paternity of the child
                        and signed an acknowledgment of paternity pursuant to Section 1-311.3 of this title,
                        or substantially similar affidavit from another state and filed it with the State
                        Registrar of Vital Statistics.
                     
                     Okla. Stat. Ann. tit. 63, § 1-311(D)(2)(a), (b) (West 2024); see also Okla. Admin. Code § 310:105-3-1(a)(3) (West 2024).  
                     
                     This statutory requirement for written consent or court determination of paternity
                        to name a father on a non-marital child’s birth certificate - presently set forth
                        in Okla. Stat. Ann. tit. 63, § 1-311(D)(2)(a), (b) – has existed in prior versions
                        of this statute since 1963. See Okla. Laws 1963, c. 325, art. 3, § 311 (effective July 1, 1963).  
                     
                     In summary, to be named as the father on a non-marital child’s Oklahoma birth certificate,
                        there must be a court determination of paternity or both the father and mother must
                        provide written consent by signing a voluntary acknowledgment of paternity form.  Consistent
                        with this law, the Oklahoma State Department of Health website provides forms for
                        Acknowledgment of Paternity, Denial of Parentage, Rescission of Acknowledgment of
                        Paternity and Rescission of Denial of Paternity.  See Vital Records Forms (last visited Jan. 23, 2025). The Acknowledgment of Paternity form (03PA209E) is
                        described as a “[v]oluntary form to be signed by unmarried parents to add the name
                        of the natural father on their child’s official birth certificate.” Id. The Oklahoma Human Services website concerning child support services explains:
                        “When a child is born to parents who are not married to each other, hospitals must
                        give an Acknowledgment of Paternity (03PA209E) form to the parents. The hospitals
                        must also give paperwork and tell the parents of their rights and duties when establishing
                        paternity.” Oklahoma Child

                     Consequently, in applying agency policy set forth in POMS GN 00306.105C.2, 3 and POMS GN 00306.120B.2 relating to use of the EAB Numident and birth certificate as evidence of written
                        acknowledgment or proof of court order for 216(h)(3) child status, where a father
                        is named on a non-marital child’s Oklahoma birth certificate, the agency may presume
                        that there has been a written acknowledgment of paternity or a court determination
                        of paternity. See Okla. Stat. Ann. tit. 63, § 1-311(D)(2)(a), (b). As noted above, the same information
                        collected by the State’s vital statistics office for the State-issued birth certificate,
                        which would include the father’s name, is also transmitted to SSA as part of the EAB
                        process. See POMS RM 10205.001B, RM 10205.005B, RM 10205.505.  
                     
                     You asked in particular whether this NH, who died on July XX, 2024, had to provide
                        written consent to be named as the Claimant’s father on the Claimant’s Oklahoma birth
                        certificate where the Claimant was born on December XX, 2020, and her mother was not
                        married to the NH (or to anyone else). You provided the Claimant’s EAB Numident record
                        listing the NH as her father as evidence of his written consent. As detailed above,
                        Oklahoma law requires a father’s written acknowledgment or a court determination of
                        paternity to be identified as the father of a non-marital child on the birth certificate.
                        The same information collected by the State’s vital statistics office for the State-issued
                        birth certificate, which would include the father’s name, is also transmitted to SSA
                        as part of the EAB process. See
                           POMS RM 10205.001B, RM 10205.005B, RM 10205.505. This Claimant’s EAB Numident is dated December XX, 2020 and: shows a “6” in the
                        FMC field of the INTERNAL line indicating it is an EAB record; shows the NH’s name
                        in the FNA field; and does not show a name other than the NH’s in the same FNA field
                        in iterations following EAB. See POMS GN 00306.105C.3. Accordingly, because the Claimant’s EAB Numident names the deceased NH as her father,
                        there is support for the agency to find that the Claimant’s EAB Numident is evidence
                        of the NH’s written acknowledgment for purposes of deeming the Claimant to be the
                        NH’s child[6] under section 216(h)(3) for Title II benefits.[7]
