What this document is

This is the standard power of attorney of the Thai Department of Lands (กรมที่ดิน) — form T.D. 21 (ท.ด. 21) with the printed subject “แบ่งหักเป็นที่สาธารณประโยชน์”: subdividing part of a plot for public use. A landowner holding a title deed (โฉนดที่ดิน) issues it when part of the land is to become a public road, lane (soi) or canal and a representative will handle the matter at the land office.

The form is one page and in Thai only. The powers are already printed: applying for the survey, bringing the surveyor, placing boundary markers and certifying boundaries, agreeing to correct the map and area if they differ, amending the application, registering the subdivision, paying and collecting back the remaining survey deposit, receiving the title deed and making statements to the officer.

Who fills it in and where it is used

  • the principal — the landowner whose land is partly given over to public use;
  • the agent — the person who goes to the land office instead;
  • the power of attorney is presented at the land office (สำนักงานที่ดิน) where the land is located.

What goes on the form

  • land details from the title deed: map sheet (ระวาง), parcel number, survey page, deed number, tambon, amphoe, province;
  • place and date of signing (Buddhist year, พ.ศ.);
  • principal and agent: name in Thai script, age, ethnicity (เชื้อชาติ), nationality, parents’ names, registered address, phone;
  • what becomes public land — road, soi or canal (a short gap in the powers text);
  • Thai ID numbers and signatures of the principal and two witnesses — by hand.

Documents usually needed

  • the original title deed;
  • copies of the ID cards and house registrations of the principal and the agent (signed as true copies).

The form does not list all required documents, fees, the survey deposit or processing times — check with the land office. The form refers to a warning on the reverse side; the official file has no reverse side.

Frequently asked questions

What is this power of attorney for?

It lets another person handle, at the land office, the survey and subdivision of part of your plot for public use — a road, lane or canal — and make statements to the officer on your behalf.

How does it differ from the power of attorney for transfer for public use?

This form has the printed subject “แบ่งหักเป็นที่สาธารณประโยชน์” — part of a plot is separated by survey. To transfer an existing plot, the Department of Lands has a separate form with the subject “โอนเป็นที่สาธารณประโยชน์”.

In which language is it filled in?

The form is Thai only: names, addresses and the land location are written in Thai script, as on the ID card, house registration and title deed; the year follows the Buddhist calendar.

What goes in the gap “(ถนน/ซอย คลอง……)”?

Briefly, what exactly becomes public: a road, soi or canal, and its name if there is one. If unsure, check with the land office.

Are witnesses required?

Yes, the form has lines for two witnesses who confirm the principal’s signature or fingerprint. Signatures are handwritten.

How much does the survey cost and how long does it take?

The form does not say. Check the survey deposit, fees and timing with the land office where the land is located.
