Thailand DTV visa for family: spouse and children of a DTV holder

A DTV holder does not receive one family visa that automatically covers a spouse and children. Each dependant has a separate visa application and receives a separate decision. The link between those applications is the principal holder’s approved DTV plus formal evidence of the family relationship.

As of 30 August 2026, the core DTV family category covers a spouse and children under 20. That sounds simple until the relationship does not fit the standard documents: an unmarried partner, a child close to the age limit, a step-family with different surnames, or an overseas civil-status record that needs translation or certification. Those are mission questions, not details to solve after payment.

Financial evidence is equally mission-specific. The central DTV material uses a THB 500,000 benchmark, but posts differ on whose bank statement can be used and whether sponsorship is accepted. Washington allows family bank evidence and sponsorship in its published guidance, Seoul expressly allows a parent’s bank statement for a child with relationship evidence, and Singapore publishes its own sponsorship conditions.

This page therefore stays narrow. It explains the dependant relationship, the separate-application logic and the family documents that make the file work. For the full DTV application process, bank-history rules and general cost planning, use the dedicated application guide rather than duplicating that material here.

The core dependant route is for a DTV holder’s legally documented spouse and children under 20. A marriage certificate is the normal relationship document for a spouse. A birth certificate usually links a child to the holder, while an adopted child relies on formal adoption evidence.

Living together is not the same evidential category as being a spouse. Central guidance uses the word spouse, and some missions draw the line expressly: Singapore states that a civil partnership certificate is not accepted for its DTV family route. If the relationship is not a registered marriage, do not assume another form of partnership will be treated as equivalent.

The under-20 rule also deserves care around edge cases. Official DTV material states children under 20; Singapore additionally describes eligible children as unmarried and under 20. A child approaching the threshold, already married, or relying on an unusual guardianship arrangement should be checked against the exact post before the fee is paid.

Different surnames are not inherently a problem, but they make the documentary chain more important. A marriage record can explain a spouse’s name change, while a birth or adoption record should connect the child to the DTV holder without forcing the officer to infer the relationship from matching addresses or family statements.

Parents of a DTV holder are not part of the core MFA description of this category, which is framed around spouse and children under 20. If one post publishes a broader local wording, treat that as that mission’s rule rather than a global expansion of the DTV family category.
