Power of Attorney to Transfer Land for Public Use (Thai Department of Lands, T.D. 21)

หนังสือมอบอำนาจ (ท.ด. 21) is the standard power of attorney form of Thailand’s Department of Lands (กรมที่ดิน). This version has the subject “โอนเป็นที่สาธารณประโยชน์” — transfer for public use — printed on it. With it the landowner (principal) authorises another person (agent) to register, at the Land Office, the transfer of the whole plot described on the form for public use (ที่สาธารณประโยชน์ — for example, for a road or a path) and to give statements to the officer until the registration is completed.

The form records the land as shown on the title deed (โฉนด): map sheet, land number, survey page, deed number, sub-district, district and province. The powers text is fully printed; additional powers can be added if needed. The form is filled in in Thai.

• the principal — the landowner named on the title deed (ผู้มอบอำนาจ);
• the agent — the person who goes to the Land Office (ผู้รับมอบอำนาจ);
• two witnesses who certify the principal’s signature or fingerprint.

If only part of the plot is transferred, the Department of Lands has a separate form — “แบ่งหักเป็นที่สาธารณประโยชน์”.

• place and date (year in the Buddhist Era, พ.ศ.);
• land details from the โฉนด title deed;
• name, Thai ID number, age, race, nationality, parents’ names, address and phone of the principal and the agent;
• additional powers — if needed;
• signatures of the principal and two witnesses — by hand.

• the original title deed (โฉนดที่ดิน);
• copies of the principal’s ID card and house registration, signed by the principal;
• the agent’s ID card or passport.

The exact list of documents, fees and processing times are not stated on the form. The office may also ask for documents from the authority that accepts the land. Check with the Land Office (สำนักงานที่ดิน) where the plot is registered.

1. Open the chat on this page and describe the situation in any language: which plot is transferred and who will be the agent.
2. Send photos of the title deed and ID cards or answer the questions — the assistant writes the data in Thai script and converts the year to พ.ศ.
3. Check the fields and download the PDF.
4. Print it, sign in front of two witnesses and hand it to the agent with the title deed and document copies.
