The Royal Thai Embassy in Washington, D.C. provides registration services for Thai nationals currently residing in the 13 states within its jurisdiction, as follows:

1. The married couple must submit the marriage registration application in person at the Consular Section of the Royal Thai Embassy.

2. One of the spouses must be a Thai citizen. 

3. If the male spouse is not a Thai citizen, he must provide a certificate of single status and a letter of employment or income certification from his office or employer.

4. Both spouses must be at least 17 years old, according to Thai law (Civil and Commercial Code, B.E. 2535, Sections 1436 and 1454). If either spouse is under 17 years old, parental consent is required.

5. If one spouse is a Thai government official, a student under the supervision of the Office of Educational Affairs, or employed by any Thai government agency, approval for marriage registration must be obtained from the respective authority.

6. If either spouse has been previously registered for marriage, the party who has been previously registered must present a divorce certificate.

7. If the female spouse has been previously registered for marriage, she must proceed with a divorce from her previous spouse and change her last name in her passport and household registration to her maiden name before re-registering the marriage. This is only applicable to individuals who were previously married before June 5, 2003, and a new marriage can only be registered if at least 310 days have passed since the end of the previous marriage, except in cases of childbirth during this period, remarriage to the same spouse, a medical certificate stating that she is not pregnant, or a Thai court order allowing the marriage.

8. If the marriage was previously registered in the United States, you must update your family status in the Thai civil registration system. More information can be found by clicking here.
