What this document is
This is the T.D. 21 power of attorney form (หนังสือมอบอำนาจ) of the Thai Department of Lands (กรมที่ดิน) for accepting a partial sale with right of redemption (รับซื้อฝากเฉพาะส่วน) — acquiring a share of a land plot under a sale with right of redemption (ขายฝาก).
In such a sale ownership of the share passes to the buyer, but the seller may buy it back within the agreed period for the agreed redemption price (สินไถ่). The buyer (ผู้รับซื้อฝาก) issues this power of attorney when they cannot attend the land office in person.
The Thai Civil and Commercial Code limits the redemption period for immovable property to 10 years and the redemption price to the sale price plus at most 15% per year. A separate 2019 Act protects sellers of agricultural and residential land under such sales; check the exact conditions with the land office.
Who fills it in and where it is filed
- the principal — the buyer of the share under the right of redemption;
- the agent — the person who will represent the principal at the land office;
- the power of attorney is filed with the land office (สำนักงานที่ดิน) where the land is located, together with the deal documents;
- foreigners generally cannot acquire land in Thailand, so the principal in this deal is usually a Thai citizen; a foreigner may act as the agent.
What the form asks for
- land details from the title deed: map sheet, land number, survey page, title deed number, sub-district, district, province;
- place and date (year in the Buddhist Era, พ.ศ.);
- principal and agent: name in Thai script, Thai ID, age, ethnicity, nationality, parents' names, address, phone;
- any building included in the deal (house / building / row house, storeys, number, house number);
- redemption period in years, the seller, the sale price and the redemption price — in digits and in words;
- the principal and two witnesses sign by hand.
Documents usually attached
- signed copies of the ID card and house register (ทะเบียนบ้าน) of the principal and the agent; a foreigner attaches a passport copy;
- the title deed (โฉนดที่ดิน), provided by the seller;
- where relevant, spouse consent and name-change documents.
The form does not list all attachments, fees or processing times — check them with the land office.
