463 U.S. 248 (1983) (U.S. Supreme Court)
Lehr v. Robertson is a cornerstone Supreme Court decision defining the constitutional contours of unwed fathers' rights in adoption and custody proceedings.
Does the Due Process or Equal Protection Clause of the Fourteenth Amendment require a state to provide notice and an opportunity to be heard to an unwed biological father in a step-parent adoption when the father has not developed a substantial relationship with the child and has not complied with state procedures (such as registering as a putative father) that would entitle him to notice?
A mere biological link between an unwed father and his child does not, by itself, create a constitutionally protected liberty interest requiring notice or participation in adoption proceedings. An unwed father's due process protection arises when he has established a substantial relationship by grasping the opportunity to assume parental responsibilities. A state may condition notice of adoption proceedings on the father's compliance with reasonable procedures (e.g., a putative father registry). Equal protection is not violated where the state distinguishes between those fathers who have accepted parental responsibilities or complied with notice-enabling steps and those who have not; such distinctions are constitutionally permissible and substantially related to legitimate state interests in child welfare and administrative efficiency.
No. The Constitution does not require notice to an unwed father who has not developed a substantial relationship with his child and failed to comply with a reasonable statutory scheme (such as a putative father registry) designed to identify fathers entitled to notice. New York's notice provisions and registry system were constitutional as applied to Lehr.
Lehr is frequently cited for the principle that constitutional protections for unwed fathers turn on conduct, not merely biology. It validates state use of putative father registries and other objective criteria to determine which fathers receive notice of adoption proceedings. For exam purposes, Lehr provides the analytical framework to evaluate unwed fathers' due process and equal protection claims and to contrast outcomes depending on whether the father has provided support, lived with the child, acknowledged paternity, or complied with statutory notice mechanisms. It also cautions practitioners that filing in one forum does not guarantee notice in another absent statutory linkage, underscoring the importance of following jurisdiction-specific procedures.
