Power of Attorney for Subdividing Land for Sale (Thai Department of Lands, T.D. 21)

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 «แบ่งขายที่ดิน»: subdivision of land for sale. The owner of a plot with a title deed (chanote, โฉนดที่ดิน) uses it to split off part of the land and sell it to a buyer 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 applies for a subdivision survey for sale to the named buyer, brings the surveyor, places boundary markers and certifies the boundaries, consents to correcting the map or area if the survey differs, amends the application if needed, registers the subdivision and sale, pays and collects back the remaining survey deposit, receives the title deed and gives statements to the land officer.

• the grantor — the owner of the plot from which the portion for sale is split off;
• the attorney — the person who acts at the land office on the grantor's behalf;
• the buyer of the new portion is named in the text of the authority;
• the power of attorney is presented at the land office (สำนักงานที่ดิน) where the plot is located;
• as a general rule foreigners cannot acquire land in Thailand — check the buyer's eligibility with the land office.

• 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;
• title and name of the buyer of the subdivided portion;
• additional powers, if needed;
• handwritten signatures of the grantor and two witnesses.

The price, area and boundaries of the portion are not on the form: they are set by the survey and by the transaction documents at the land office.

• the original chanote of the plot;
• copies of the ID cards and house registrations of the grantor and the attorney (signed as true copies);
• the buyer's documents for registering the sale.

The form does not list the full set of documents, fees, the survey deposit or processing times — check them with the land office. The form refers to a warning on the back; the official file has no back page.
