Marriage in Thailand is governed by the Civil and Commercial Code book 5, sections 1435 to 1535. A marriage (section 1457) can take place only if the man and woman (who are at least 18 years old) agree to take each other as husband and wife, and such agreement must be declared publicly before the Registrar in order to have it recorded by the Registrar. Marriage in Thailand is created and completed on formal registration and inclusion in the government's marriage register.
