Oklahoma bans marriage under 18 from today, with no exceptions
From today, 1 November 2026, no one under the age of 18 can get married in Oklahoma. Senate Bill 504 sets 18 as the minimum age for a marriage licence in the US state, with no exceptions at all.
Under the old law, 16- and 17-year-olds could marry with a parent’s consent, and children under 16 could marry with a judge’s permission in limited cases. From today, parental consent, pregnancy and court approval no longer qualify anyone under 18. The change is not retroactive, so marriages that took place before 1 November are not affected.
The bill became law in May without the signature of Governor Kevin Stitt. It passed the Senate unanimously and cleared the House 51 to 36. Oklahoma is the 17th US state to ban child marriage outright, joining at least 16 other states that have already done so. It is one of more than 230 new Oklahoma laws taking effect on 1 November, the state’s default start date for bills passed without an emergency clause.
Why it matters
Supporters of the ban say the old rules left children open to pressure and coercion. State Senator Warren Hamilton, who championed the bill, said the young people involved “are minors who are vulnerable and need legal protections from those who seek to prey upon them.” Oklahoma had been one of the few US states where children could still legally marry once parental and court exceptions were counted.
What happens next
County clerks across Oklahoma will now require proof that both people applying for a marriage licence are at least 18. Campaigners will be watching whether other states follow, as many US states still allow marriage under 18 in some circumstances.
