What this document is
หนังสือมอบอำนาจ (ท.ด. 21) is the standard power of attorney form of Thailand’s Department of Lands (กรมที่ดิน). This version has the subject “โอนให้ตัวการ” — transfer to the principal — printed on it. It is used when land is registered in the name of a person who acquired it as an agent (ตัวแทน) on behalf of someone else — the principal (ตัวการ) — and the land is now transferred to that principal. With it the registered owner (grantor) authorises another person (agent) to register the transfer at the Land Office: 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 transferred with it) and the principal. FoxDocs fills in an individual principal (นาย/นาง/นางสาว): it circles the title and strikes out “หรือบริษัท … จำกัด”. If the principal is a company, its name is written on the form by hand — the space is too small for print. The form is filled in in Thai.
Who takes part
- the grantor — the owner named on the title deed (ผู้มอบอำนาจ), who transfers the land;
- the agent — the person who goes to the Land Office (ผู้รับมอบอำนาจ);
- the principal (ตัวการ) — the person or company receiving the land; named in the powers text;
- two witnesses who certify the grantor’s signature or fingerprint.
If the agent is the principal or represents the principal, the note on the form requires adding the consent «และยินยอมให้ผู้รับมอบอำนาจเข้าทำการแทนในนามตนเองและ/หรือเป็นตัวแทนของอีกฝ่ายหนึ่งด้วย»: the agent acts both in his or her own name and on behalf of the other party.
What the form asks for
- place and date (year in the Buddhist Era, พ.ศ.);
- land details from the โฉนด title deed;
- name, age, race, nationality, parents’ names, address and phone of the grantor and of the agent; the Thai ID number (13 boxes) is written in by hand by the grantor and the agent — the service does not print it;
- the building on the land (house, building or shophouse, storeys, house number) — if transferred together with the land;
- the individual principal: title (นาย/นาง/นางสาว) and name in Thai script;
- signatures of the grantor and two witnesses — by hand.
Documents usually attached
- the original title deed (โฉนดที่ดิน);
- copies of the grantor’s ID card and house registration, signed by the grantor;
- the agent’s ID card or passport;
- where relevant — documents showing the agency relationship, marital status documents or the spouse’s consent, and for a company its certificate of registration (หนังสือรับรอง).
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. The officer examines the circumstances of the agency; such a transfer does not make lawful an arrangement the law prohibits (for example holding land for a foreigner), so check this in advance.

- Print it, sign it before two witnesses and hand it to the agent with the title deed and copies of documents.
