Names — United States

A court petition in most states, usually with publication — and a marriage certificate is enough to take a spouse's name.

The legal framework

Name change is a state matter. Adults normally file a petition in the county court, which may require publication in a newspaper and a criminal background check, before an order is granted. Marriage and divorce provide simpler routes, using the certificate or decree. Some states allow gender marker changes by self-attestation; others require medical evidence.

In practice

Cost and coverage

Filing fees of roughly one to five hundred dollars, plus publication costs; fee waivers are available for low-income applicants.

Recent changes

Requirements for changing gender markers on federal and state documents have shifted repeatedly; check the current position rather than relying on older guidance.

Where to go

Worth knowing

If publication would expose you to danger, ask the court for a waiver: most states allow sealed or confidential name changes for survivors of domestic violence and stalking. The order in which you update records matters: agencies verify against each other, and starting in the wrong place causes repeated rejections.
