Written by attorneys · grounded in primary & secondary sources — see below
A statutory presumption that an individual is the legal parent of a child when the individual is married to the woman who gives birth and the child is born during the marriage or within three hundred days after its termination. The presumption attaches automatically from the marital relationship and timing of birth. It persists unless overcome by a judicial adjudication or a valid statutory denial of parentage.

Spouse Presumption After Separation
Paige Porter and Penelope Price separated but never divorced. Penelope gave birth eleven months later during a brief relationship with Preston Pratt. Preston sought to be named the legal parent on the birth certificate. The court treated Paige as the presumed parent because the child was born while the marriage remained legally intact. No adjudication or valid denial had occurred to displace the presumption.
Nonbirthing Spouse in Same-Sex Marriage
Pilar Pena gave birth while married to Phuong Pham. The couple had lived together since the birth and listed Phuong on employer benefits as the child's second parent. A former partner later obtained genetic testing showing a biological link and petitioned for parentage. The court held that Phuong remained the presumed parent because the child was born during the marriage and no adjudication had yet overcome the presumption.

Common questions
Frequently Asked
5
Does proof of a biological link automatically displace a marital presumption of parentage?+
No. A later-proven genetic connection does not by itself terminate the presumption. The presumption continues unless overcome through a proper judicial adjudication or a valid formal denial of parentage.
Supporting sources
When does the marital presumption attach if the spouses were separated at conception?+
The presumption attaches if the child is born during a legally intact marriage or within three hundred days after its termination by divorce or death. Physical separation or the spouses' subjective belief that the marriage had ended does not prevent the presumption from arising.
Can a presumed parent lose status simply because another adult has been acting as caregiver?+
No. Daily caregiving alone does not create a competing presumption or displace an existing marital presumption. The marital presumption remains effective until rebutted by adjudication or valid denial.
Supporting sources
Does a legal separation agreement end the marital presumption of parentage?+
No. A separation agreement or decree does not terminate the marriage. The presumption therefore continues if the child is born within three hundred days after the marriage ends by death or other final decree.
Supporting sources
May a genetic parent commence a parentage action after the child reaches adulthood?+
Generally no. A proceeding to overcome a presumption may be brought after the child becomes an adult only if the child initiates it. An outside claimant lacks standing to file independently once the child is an adult.
