Unwed Father Seeks Hearing
Faith Fitzgerald had lived with and cared for her nonmarital child since birth. After the mother died, state officials removed the child without notice or hearing under a rule that treated all unwed fathers as mere financial sponsors. The court held that the established family unit created a protected liberty interest requiring an individualized determination before severance.
Homemaker Contribution in Divorce
Francois Fortier and his spouse accumulated assets during a twelve-year marriage. The court apportioned the estates by treating the couple as a single economic unit and credited the homemaker spouse's contributions to preservation and appreciation of marital property.

Biological Father Seeks Notice
Felipe Figueroa had never formed a custodial relationship with his child. When the mother placed the child for adoption, the state denied him notice of the proceeding. The court ruled that the absence of an established family unit meant no constitutional entitlement to notice arose.
Lehr v. Robertson et al.463 U.S. 248 (1983)
Zoning Limits Extended Family
Felix Franco lived with his grandson and great-grandson in a single-family zone. City inspectors cited the household for violating an ordinance that counted only nuclear family members. The court invalidated the restriction because it intruded on the protected family unit formed by blood and sustained cohabitation.
Moore v. City of East Cleveland, Ohio431 U.S. 494, 503 (1977)
Foster Parents Seek Standing
Fatima Flores and her partner had served as long-term foster parents to two siblings. When the agency planned to remove the children, the foster parents asserted a liberty interest in the existing family unit. The court held that foster placements lack the same constitutional status as biological or adoptive family units.
Smith v. Organization of Foster Families For Equality and Reform (OFFER)431 U.S. 816, 862-863
Illegitimate Child Inheritance
Fernando Farrell died intestate after acknowledging his nonmarital child. State law barred the child from inheriting because the parents never married. The court struck down the statute because it penalized the child for the absence of a formal family unit without advancing a substantial state interest.
Trimble v. Gordon430 U.S. 762, 775 n.16 (1977)
Common questions
Frequently Asked
5
When does an unwed father receive constitutional protection for his relationship with a nonmarital child?+
Protection arises when the father has formed a family unit through sustained caregiving and co-residence. The state may not remove the child without notice and an opportunity to be heard on fitness and the child's best interests.
How does treating the family as an entity affect property division in divorce?+
Courts view the spouses as a single economic unit and consider each party's contributions to acquisition, preservation, and appreciation of assets, including homemaker services, when making equitable apportionment.
Does a zoning ordinance that restricts household composition to nuclear family members violate the Constitution?+
Yes when the ordinance intrudes on an extended family unit formed by blood and sustained cohabitation without advancing a legitimate zoning objective.
Why do foster parents generally lack the same constitutional protections as biological parents?+
Foster relationships are created by contract with the state and lack the permanence and biological ties that define a protected family unit under the Due Process Clause.
What constitutional flaw exists in statutes that bar illegitimate children from inheriting unless the parents marry?+
Such statutes penalize the child for the parents' failure to form a formal family unit and lack a substantial relation to any legitimate state interest in promoting legitimate families.
