Bill No. 504 amends the eligibility requirements for marriage in Oklahoma by establishing a strict age restriction. Under the new provisions, only unmarried individuals who are at least eighteen years old are permitted to marry, effectively removing all exceptions that previously allowed individuals under this age to enter into marriage under certain circumstances. The bill deletes various conditions that allowed minors to marry, such as parental consent, court authorization in specific situations, and exceptions for those under sixteen years of age.

Additionally, the bill updates the statutory reference and clarifies that no marriage may be authorized if it would be considered incestuous. The changes are set to take effect on November 1, 2026, reinforcing the state's commitment to ensuring that individuals are of legal age before entering into marriage.
