Procedures

Marriage registration can be filed at any District Office or Minor District Office nationwide regardless of the birthplace of the couple.

Once the marriage registration is completed, each party will be given a copy of the Marriage Registration Certificate as evidence.

If the marriage registration is filed at the District Office located in female's birthplace (where the name is registered on the House Registration Certificate), the title used with the forename and the last name of the female will be changed by the District Officer. The female is required to file for a new Identification Card within 60 days. A service fee of 10 Baht is required. If the marriage is registered elsewhere, the female is required to contact the local District Office to change her name and last name, as well as filing for a new Identification Card.

If both parties are unable to file for marriage at any District Office of Minor District Office, the couple can submit a request to the Registrar to register their marriage at any location under the supervision of that District Office. The parties filing for marriage are required to provide transportation for the Registrar. A service fee of 400 Baht is required by the ministry. **This is not normally available**
