Power of Attorney for Change of Estate Administrator's Name on a Title Deed (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 “โอนเปลี่ยนนามผู้จัดการมรดก” printed on it — transfer of the estate administrator’s name. It is used when a title deed is recorded in the name of an estate administrator and a court has since appointed another person as administrator: the new administrator (principal) authorises an agent to register at the Land Office that the deed passes from the previous administrator’s name to his or her own.

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 printed powers text names the previous administrator and the court order — the court, the red case number and the date of the order. The form is filled in in Thai.

• the principal — the new estate administrator appointed by the court (ผู้มอบอำนาจ);
• the agent — the person who goes to the Land Office (ผู้รับมอบอำนาจ);
• the previous administrator — the person currently recorded on the deed; only named in the powers text;
• two witnesses who certify the principal’s signature or fingerprint.

• 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 of the agent;
• the title and name of the previous administrator as shown on the deed;
• the court, the red case number and the date of the court order;
• signatures of the principal and two witnesses — by hand.

• the original title deed (โฉนดที่ดิน);
• a certified copy of the court order appointing the principal as estate administrator;
• 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 time are not stated on the form — check with the Land Office (สำนักงานที่ดิน) where the land is registered.

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