What Is an Affidavit of Paternity

An affidavit of paternity, formally a voluntary acknowledgment of paternity (AOP), is a sworn instrument by which an unmarried mother and a man establish legal parentage without court proceedings. Federal Title IV-D of the Social Security Act (42 U.S.C. § 666(a)(5)(C)) requires every state to maintain a paternity-acknowledgment program meeting federal procedural standards including hospital availability, written rights-and-responsibilities notice, and a defined rescission window. The Uniform Parentage Act (UPA) Article 3, adopted in some form by 19 states including Washington, Texas, Delaware, and Wyoming, codifies acknowledgment procedures and substantive requirements. Once filed with state vital records, the AOP has the legal effect of a judgment of paternity for purposes of child support, inheritance, and federal benefits.

The federal program traces to the 1996 welfare reform under the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA, Pub. L. 104-193), which conditioned state IV-D funding on creation of voluntary-acknowledgment programs as an alternative to paternity litigation. The reform was designed to reduce administrative caseloads and accelerate child support establishment by replacing months-long paternity actions with hospital-based acknowledgment. The result is the same legal certainty as a court judgment, available at the bedside immediately after birth.

UPA Article 3 framework and state implementations

UPA Article 3 governs voluntary acknowledgment in adopting jurisdictions. The procedural requirements include execution before a notary or designated witness, written rights-and-responsibilities notice in plain language, and filing with the state registrar of vital statistics. Texas Family Code § 160.302 requires notarization plus the federal rights notice. California Family Code § 7574 permits witness signature in lieu of notarization. New York Public Health Law § 4135-b governs hospital-based acknowledgment. Florida Stat. § 742.10 codifies the federal Title IV-D framework. The substantive rules are largely uniform; the procedural details (notary requirement, witness adequacy, post-hospital filing process) vary by state.

Rescission window and post-window challenge grounds

Federal law (42 U.S.C. § 666(a)(5)(D)(ii)) requires states to permit rescission within the earlier of 60 days from signing or the date of the first administrative or judicial proceeding relating to the child in which the signer is a party. After the rescission window closes, challenge requires court action under state law on grounds of fraud, duress, or material mistake of fact (Cal. Fam. Code § 7575, Tex. Fam. Code § 160.308, NY Family Court Act § 516-a). DNA evidence excluding the acknowledged father is generally insufficient on its own to set aside the AOP; the petitioner must show one of the three substantive grounds plus prompt filing, typically within two years of discovery under most state codes. The set-aside standard is intentionally rigorous to protect the child's status from belated paternity disputes.
