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 “ผู้จัดการมรดกเฉพาะส่วน” — estate administrator for a share — printed on it. With it the estate administrator (principal) authorises another person (agent) to register the administrator’s name on the โฉนด title deed at the Land Office for the deceased co-owner’s share only, to give statements to the officer and to sign until the registration is completed.
The form records the land as shown on the title deed (map sheet, land number, survey page, deed number, sub-district, district, province), the name of the deceased co-owner and the basis of the appointment — a will (พินัยกรรม) or a court order (คำสั่งศาล) — with the court, the “red” case number and the date. It is filled in in Thai, with the year in the Buddhist Era (พ.ศ.).
Who makes it
- the principal — the estate administrator (ผู้จัดการมรดก) appointed by will or court order;
- the agent — the person who goes to the Land Office (ผู้รับมอบอำนาจ);
- two witnesses who certify the principal’s signature or fingerprint.
It is used when the deceased owned the land together with other co-owners and the administrator is registered for the deceased’s share only. If the deceased owned the whole plot, the Department of Lands has a separate form — check with the office.
What the form asks for
- place and date (year in the Buddhist Era, พ.ศ.);
- land details from the โฉนด title deed;
- title and name of the deceased co-owner;
- how the administrator was appointed: will or court order; court, หมายเลขแดง case number and date;
- name, Thai ID number, age, race, nationality, parents’ names, address and phone of the principal and of the agent;
- signatures of the principal and two witnesses — by hand.
Documents usually attached
- copies of the principal’s ID card and house registration, signed by the principal;
- the agent’s ID card or passport;
- the court order appointing the estate administrator, or the will;
- the co-owner’s death certificate and the original title deed.
The exact list, fees and processing time are not stated on the form — check with the Land Office (สำนักงานที่ดิน) where the land is registered.
