   2. (ii) that if an acknowledgment of parentage is not made, the signatory other than the birth parent can be held liable for support only if the family court, after a hearing, issues an order declaring that the person is the parent of the child whereupon the court also may issue an order of support which may be retroactive to the date of the birth of the child;

   6. (vi) that a copy of the acknowledgment of parentage will be filed with the registry created by section 372-c of the Social Services Law and that such filing may establish the child's right to inheritance from the alleged parent or intended parent pursuant to clause (B) of the subparagraph (2) of paragraph (a) of section 4-1.2 of the Estates, Powers and Trusts Law;
   7. (vii) that if the acknowledgment of parentage is filed with the registrar of the district in which the birth certificate has been filed, such acknowledgment will establish inheritance rights from the alleged parent or intended parent pursuant to clause (A) of subparagraph (2) of paragraph (a) of section 4-1.2 of the Estates, Powers and Trusts Law;

   8. (viii) that no further judicial or administrative proceedings are required to ratify an unchallenged acknowledgment of parentage provided, however, that:

   12. (xii) that the birth parent’s refusal to sign an acknowledgment of parentage is not deemed to be a failure to cooperate in establishing parentage for the child; and
   13. (xiii) that the child may bear the last name of either parent, or any combination thereof, which name will not affect the legal status of the child.

3. (3) Review of acknowledgment of parentage. The child support enforcement unit must review the acknowledgment of parentage to ensure it is on the form developed by the office for such use, responses are legible and complete, including but not limited to the following information:

5. (5) Records relating to acknowledgments of parentage which are signed in hospitals. If an acknowledgment of parentage is signed in a hospital pursuant to section 4135-b of the Public Health Law, and if the birth parent is in receipt of child support services pursuant to title 6-A of article 3 of the Social Services Law, the child support enforcement unit located in the social services district within which the birth parent resides is entitled to secure from the registrar without charge a certified copy of the certificate of birth and a certified copy of the acknowledgment of parentage. Copies of such documents must be maintained by the support collection unit in the appropriate child support case record.
6. (6) Effect of voluntary acknowledgment of parentage. An acknowledgment of parentage signed pursuant to section 4135-b of the Public Health Law or section 111–k of the Social Services Law establishes the parentage of a child and has the same force and effect as a judgement of parentage or order of filiation issued by a court of competent jurisdiction.
