What this document is
This is the standard power of attorney of Thailand's Department of Lands (กรมที่ดิน) — form T.D. 21 (ท.ด. 21) with the printed subject «ขายที่ดินเฉพาะส่วน»: sale of a share of land. A co-owner of a plot with a title deed (chanote, โฉนดที่ดิน) uses it to sell their part through a representative instead of in person.
The form is one page and in Thai only. The text of the authority is already printed: the attorney sells the share of the plot to the named buyer at the stated price, with buildings if any, and gives statements to the land officer.
Who fills it in and where it is filed
- the grantor — the co-owner who sells their share;
- the attorney — the person who goes to the land office on the grantor's behalf;
- the power of attorney is presented at the land office (สำนักงานที่ดิน) where the plot is located when the sale is registered;
- as a general rule foreigners cannot acquire land in Thailand — check the buyer's eligibility with the land office.
What the form asks for
- plot details from the chanote: map sheet (ระวาง), land number, survey page, deed number, sub-district, district, province;
- place and date (year in the Buddhist Era, พ.ศ.);
- grantor and attorney: name in Thai script, Thai ID number, age, race (เชื้อชาติ), nationality, parents' names, registered address, phone;
- buildings on the plot if sold with it: type, storeys, number, house number;
- the buyer and the price — in figures and in words;
- handwritten signatures of the grantor and two witnesses.
Documents usually needed
- the original chanote of the plot;
- copies of the grantor's and attorney's ID cards and house registrations, signed as true copies;
- the buyer's documents for registering the sale.
The form does not state the full list of documents, fees or processing times — check them with the land office. The form refers to a warning on the back; the official file has no reverse page.
