Senate Bill No. 504 amends the eligibility requirements for marriage in Oklahoma by establishing a strict age restriction. The bill stipulates that any unmarried person must be at least eighteen (18) years old to contract and consent to marriage with a person of the opposite sex. It removes all previous exceptions that allowed individuals under the age of eighteen to marry under certain circumstances, such as parental consent or court approval. The previous legal language detailing these exceptions has been entirely deleted from the statute.

Additionally, the bill clarifies that no marriage may be authorized if it would be considered incestuous under the law. The effective date for this legislation is set for November 1, 2026. This change aims to standardize the age of marriage eligibility and eliminate the complexities associated with underage marriage exceptions.
