Power of Attorney to Accept a Mortgage of Land (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 “รับจำนองที่ดิน” — accepting a mortgage of land — printed on it. It is given by the mortgagee: the lender who takes the land as security for a loan. The agent registers the mortgage at the Land Office on the lender’s behalf: files the application, gives statements to the officer and signs until the transaction 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 names the building on the land (if it is mortgaged too), the landowner (mortgagor), the mortgage amount in figures and in words, the interest rate per month or per year and the borrower whose debt is secured. The form is filled in in Thai.

• the principal — the mortgagee, i.e. the lender (ผู้มอบอำนาจ);
• the agent — the person who goes to the Land Office (ผู้รับมอบอำนาจ);
• two witnesses who certify the principal’s signature or fingerprint.

If the agent is the other party (the mortgagor) or represents them, the note on the form requires adding consent that the agent acts both in his or her own name and on behalf of the other party.

• 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 building on the land (house, building or shophouse, storeys, house number) — if it is mortgaged together with the land;
• the landowner, the mortgage amount in figures and in words, the interest rate and the borrower;
• the Thai ID number in the boxes and the signatures of the principal and two witnesses — by hand.

• copies of the principal’s ID card and house registration (a passport for a foreigner), signed by the principal;
• the agent’s ID card or passport;
• the loan agreement or other documents on the debt — if the office asks for them.

The exact list, fees and processing time are not stated on the form — check with the Land Office (สำนักงานที่ดิน) where the land is registered. The original title deed and the mortgagor’s documents are provided by the landowner. Taking land as security is not the same as buying it, but a foreign lender should still check any restrictions with the office in advance.

1. Open the chat on this page and describe the deal in any language: who lends, who will act as agent, which plot, who owns it and the mortgage amount.
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 it before two witnesses and hand it to the agent with copies of documents.
