How does a foreigner register marriage in Thailand?

Detailed Answer

Foreigner–Thai marriage registration in Thailand requires a four-step legal chain: (1) the foreigner obtains an Affirmation of Freedom to Marry (sometimes called Statement in Lieu of Certificate of Non-Impediment) from their embassy in Bangkok — required by US, UK, Australia, Canada, Germany, France, Japan, and most embassies; (2) the affirmation is legalized at MFA Department of Consular Affairs (Chaeng Watthana); (3) the document is translated into Thai by a certified translator; (4) both parties register the marriage at any Amphur (district office) in Thailand. Thai Notary's all-inclusive package starts at THB 9,500 and includes embassy appointment booking, document prep, certified translation, MFA legalization, amphur escort, and Kor.Ror.2/3 marriage certificate pickup + post-marriage legalization for use overseas.
