A statutory presumption establishing legal parentage based on marriage to the birth parent or other specified conduct. The presumption persists until overcome by adjudication or valid denial.
Pierre Poulin and Penelope Price married in 2021 and separated without a divorce decree. Penelope gave birth in 2023 while still legally married to Pierre. Pierce Patterson later proved a genetic link and sought adjudication. The court treated Pierre as the presumed parent because no adjudication or valid denial had yet displaced the marital presumption.
Pamela Phillips gave birth during her marriage to Priscilla Parks. Priscilla resided with the child from birth and held the child out as her own on school and employment records. A former partner later sought genetic adjudication. The court recognized Priscilla as a presumed parent whose status could be challenged only through formal proceedings.
