Power of Attorney to Lease Out 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 “ให้เช่าที่ดิน” — leasing out land — printed on it. With it the landowner (principal) authorises another person (agent) to register the lease at the Land Office on his or her behalf: file the application, give statements to the officer and sign 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 names the building on the land (if leased with it), the lease term, the start and end dates, the total rent and the amount and frequency of payments. 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 the agent is the lessee or represents the lessee, 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. This form has no free space for it — ask the Land Office where to write the clause.

• 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 leased together with the land;
• the lease term in years and the start and end dates;
• the total rent in figures and in words, the payment per month or per year and the due date;
• 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;
• where relevant — marital status documents or the spouse’s consent.

The exact list, fees, taxes and processing time are not stated on the form — check with the Land Office (สำนักงานที่ดิน) where the land is registered. Under the Thai Civil and Commercial Code a lease of immovable property for more than three years must be registered, otherwise it is enforceable for three years only (section 538); the lease term may not exceed 30 years (section 540).

1. Open the chat on this page and describe the deal in any language: who leases out the plot, who will act as agent, which plot, for how long and for what rent.
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 the title deed and copies of documents.
