Unmarried Father Seeks Adoption Veto
Paula Pierce gave birth to a child after ending her relationship with Pedro Pacheco. Pedro visited the newborn weekly, paid support, and filed a paternity action within days of the birth. When Paula later consented to adoption by a third party, Pedro objected and sought custody. The court recognized his protected interest because he had manifested parental responsibility through consistent contact and financial support.
Surrogacy Parentage Dispute
Pearl Porter served as gestational surrogate for Pablo Perez and his wife under a written agreement. After delivery, Pearl sought to establish parentage in her favor. The court applied the Uniform Probate Code provision directing that parentage in assisted reproduction with a surrogate be determined under the applicable state parentage act rather than automatic genetic rules.
Nonmarital Child Support Claim
Parker Phillips, a nonmarital child, filed a paternity suit six years after birth seeking support from his alleged father. State law barred such actions after six years for nonmarital children while allowing marital children to seek support indefinitely. The court struck down the limitation because it failed intermediate scrutiny and was not substantially related to preventing stale claims.
Sperm Donor Without Written Agreement
Peter Park donated sperm to a recipient under an oral understanding that he would have no parental rights. Years later he sought visitation after learning the child had been born. The court denied his claim because Kansas law requires a written agreement to preserve donor paternity and no such writing existed.
Inheritance Claim After Father's Death
Pablo Perez died intestate leaving substantial assets. His nonmarital daughter Pearl sought to inherit but had never obtained a lifetime paternity adjudication. State law conditioned nonmarital inheritance on such an adjudication. The court upheld the requirement as substantially related to the orderly administration of estates and denied the claim.
Illegitimate Child Inheritance Barred
Pedro Pacheco died leaving an estate. His nonmarital son Parker had lived with him and received support but never obtained a formal paternity decree during life. State probate law limited inheritance by nonmarital children to those whose paternity was established before death. The court enforced the rule and excluded Parker from the estate.

Common questions
Frequently Asked
6
What must an unmarried biological father show to gain the right to object to adoption?+
He must demonstrate actual manifestations of parental responsibility such as living with the child, visiting regularly, admitting paternity, paying support, and showing willingness to assume custody rather than merely blocking adoption.
How is parentage determined when a child is born to a gestational surrogate under the Uniform Probate Code?+
Parentage is determined under the Uniform Parentage Act Article 8 or equivalent state parentage statutes rather than automatic genetic or gestational presumptions.
Why did the Supreme Court invalidate a six-year limitations period for nonmarital children's paternity suits?
+
The statute failed intermediate scrutiny because it was not substantially related to the state's interest in preventing stale or fraudulent claims when marital children faced no such limit.
Under Kansas law, when does a sperm donor acquire parental rights?+
Only when a written agreement with the recipient expressly preserves the donor's paternity. Without the writing the donor has no legal parent status.
May a state require lifetime establishment of paternity before a nonmarital child may inherit intestate?+
Yes, because the requirement is substantially related to the important governmental interest in orderly and efficient disposition of property at death by reducing fraud and uncertainty.
What constitutional standard applies to classifications based on illegitimacy in inheritance statutes?+
Intermediate scrutiny requires that the classification be substantially related to an important governmental objective such as preventing fraud in estate administration.
