Oklahoma Gov. Stitt signed HB 1225 requiring birth certificates to list sex assigned at birth and barring gender-identity amendments

On May 7, 2026, Oklahoma Gov. Kevin Stitt signed House Bill 1225 into law after both chambers of the Legislature passed it during the 2026 regular session. The measure requires that every Oklahoma birth certificate record the person's biological sex — male or female — as identified at the time of birth, and it prohibits amending that designation to reflect gender identity, a nonbinary status, or an "X" marker. The bill amends the state's vital-records statutes governing birth-certificate filing, amendments, delayed registrations, and post-adoption certificates, and it carried an emergency clause that made it effective upon the governor's approval.

In practice the law forecloses the ability of transgender and nonbinary Oklahomans to obtain a birth certificate whose sex marker matches their gender identity. The House author, Rep. Kevin West (R-Moore), described the measure as ensuring that the biological sex listed at birth "is not to be amended"; the Senate author was Sen. Michael Bergstrom (R-Big Cabin). Supporters framed the bill as closing perceived loopholes left by earlier state action, and it builds on Oklahoma's 2022 SB 1100, which had already barred nonbinary markers on birth certificates.

The law writes a protected characteristic directly into a mandatory government identity record and removes any path to correct it, placing Oklahoma among the states enacting anti-transgender identity-document restrictions during the 2026 legislative cycle.
