Peter Caban and Maria Mohammed lived together in New York without marrying and had two children together. Throughout the children's early lives, Caban acknowledged paternity, lived with the family for several years, supported and cared for the children, and maintained an ongoing relationship with them even after the adults separated. Maria later married Khalil Mohammed, and the couple petitioned for Khalil to adopt the children. Under New York Domestic Relations Law § 111(1), consent to adoption of a child born out of wedlock was required from the mother but not from the biological father, unless the father had married the mother or met other conditions not applicable here. Over Caban's objection—and notwithstanding that he had established a parental bond—the state courts approved the stepfather's adoption petition, concluding that the statute did not require the unwed father's consent. Caban challenged the statute, arguing that the sex-based distinction violated the Equal Protection Clause of the Fourteenth Amendment.
Does a statute that requires the consent of an unwed mother, but not an unwed father, for the adoption of their children violate the Equal Protection Clause when the father has established a substantial relationship with the children?
Gender-based classifications are subject to intermediate scrutiny under the Equal Protection Clause and must serve important governmental objectives and be substantially related to the achievement of those objectives. While the state has legitimate interests in facilitating adoptions and protecting children's welfare, it may not rely on broad, overbroad generalizations about parental roles or sex to extinguish parental rights; where an unwed father has acknowledged paternity and developed a substantial, responsible relationship with his children, the state must accord protections comparable to those afforded an unwed mother before terminating his parental status.
Yes. New York's statute, insofar as it allowed adoption of children born out of wedlock without the consent of an involved unwed father who has developed a substantial relationship with his children, violated the Equal Protection Clause of the Fourteenth Amendment.
The Court applied intermediate scrutiny to the sex-based distinction, requiring that the law serve important governmental interests and be substantially related to those ends. New York identified goals such as promoting the best interests of children, facilitating their adoption into stable families, administrative efficiency, and the practical realities that unwed mothers may be more readily identifiable and often initially assume primary caregiving. While recognizing that mothers and fathers may not be similarly situated at the moment of birth, the Court held that those generalities cannot justify a categorical rule once a father has come forward to acknowledge paternity and has assumed significant responsibilities for the child. In Caban's case, the record showed he had lived with, supported, and maintained meaningful ties to his children. Permitting the stepfather's adoption over his objection solely because of his sex lacked a substantial relation to the state's asserted interests. The statute was both overinclusive and underinclusive: it prohibited all unwed fathers from vetoing adoptions, including those with demonstrated parental bonds, while it permitted all unwed mothers—regardless of actual relationship quality—to exercise an absolute veto. The Court emphasized that less discriminatory, better-fitted alternatives existed, such as measuring a putative father's rights by objective indicia of commitment (acknowledgment of paternity, support, cohabitation, visitation, or other evidence of a substantial relationship). The Court distinguished Quilloin v. Walcott (1978), where it had upheld a step-parent adoption over the objection of an uninvolved father who had not developed a parenting relationship. Here, by contrast, Caban's established relationship made him similarly situated to the mother for purposes of consent to adoption, and the sex-based classification could not constitutionally control the outcome.
Caban v. Mohammed limits the use of sex-based classifications in family law and affirms constitutional protections for unwed fathers who have formed substantial parental relationships. For law students, it is essential for understanding intermediate scrutiny's application to gender distinctions, the careful tailoring required when the state terminates parental rights, and the doctrinal interplay among Caban, Quilloin v. Walcott, and Lehr v. Robertson. The case also influenced legislative reforms that recognize the rights of involved unwed fathers in adoption proceedings.
Caban v. Mohammed stands for the principle that sex-based shortcuts in family law cannot extinguish the rights of an unwed father who has acted as a parent. By demanding a closer fit between the state's adoption goals and the means chosen, the Court reinforced that gender classifications must yield to evidence of actual parental relationships.
