How it applies
Common Examples

Paternity Suit Time Bar
Brian Bailey fathered a child out of wedlock with Beatrice Brown. State law gave nonmarital children only six years to sue for support while allowing marital children to seek support indefinitely. Beatrice filed on behalf of the child after the period expired. The court applied intermediate scrutiny and struck down the limit because the state failed to show it substantially advanced any interest in avoiding stale claims.
Intestate Inheritance Exclusion
Bobby Brady died without a will. State law barred his nonmarital son Benito Benitez from any share of the estate even though paternity was undisputed. Benito's marital siblings claimed everything. The court held the absolute bar unconstitutional under equal protection because it penalized the child for the parents' conduct without a substantial relation to any important state interest.

Common questions
Frequently Asked
4
What level of scrutiny applies to classifications based on bastardy?+
Classifications based on illegitimacy receive intermediate scrutiny. The state must demonstrate that the classification is substantially related to an important governmental interest.
Supporting sources
May a state absolutely bar nonmarital children from inheriting from their fathers?+
No. An absolute bar on paternal intestate inheritance by nonmarital children violates equal protection because it punishes children for their parents' conduct and lacks a substantial relationship to any important state interest.
Supporting sources
Does a six-year limitations period for nonmarital children's paternity suits violate equal protection?+
Yes when marital children face no comparable limit. The disparate deadline fails intermediate scrutiny unless the state shows it is substantially related to preventing stale or fraudulent claims.
May a state require lifetime paternity adjudication for nonmarital children to inherit?+
Yes. A requirement that paternity be formally established during the father's lifetime is substantially related to the important interest in orderly estate administration and preventing fraudulent claims.
