Thai Spouse Land Purchase Declaration: How It Works

TL;DR

When a Thai national married to a foreigner buys land, the Land Office requires a joint declaration (Khor.Tor.Sor.21 or similar) signed by both spouses confirming the funds used are sole property (Sin Suan Tua) of the Thai spouse, not communal property (Sin Som Ros). The declaration is grounded in the Civil and Commercial Code §1471-1474 on marital property and the Land Code §86 on the foreigner land-ownership restriction.

Why the Declaration?

• Without declaration, Land Office presumes the land becomes communal property — foreigners can't co-own land.
• The declaration converts the title's source to sole property, lawful under Land Code §86.
• The foreign spouse signs acknowledging no marital-property claim on the land.

Implications for the Foreign Spouse

• No legal interest in the land during marriage.
• On divorce, the Thai spouse retains the land; no community-property division.
• Inheritance: depends on Thai-spouse's will or intestate succession (CCC §1629); foreign spouse as heir may have to dispose of inherited land within 1 year (Land Code §93).

Process Steps

1. Pre-purchase due diligence on the Chanote.
2. Joint Land Office visit (both spouses, IDs, marriage certificate, passport).
3. Sign Khor.Tor.Sor.21 (or current form).
4. Pay land-transfer tax and registration.
5. New Chanote in Thai-spouse's name.

Common Mistakes

• Foreign spouse misunderstanding the declaration as a "right" to land — it's the opposite.
• Skipping the declaration — Land Office refuses registration.
• Buying via Thai-spouse name without true funds origin from Thai spouse — vulnerable to revocation.

Alternatives

• Long lease (30 years renewable).
• Usufruct (lifetime right of enjoyment).
• Superficies (right to own structure on others' land).
• Condominium (49% foreign quota).

FAQs

1. Can I bring my own funds and use Thai-spouse name?

Legally risky — Land Code prohibits nominee structures; nominee findings can void the title.
