When You Can't Be There in Person
You own a condo in Phuket, but a work commitment means you can't fly in for the Land Office appointment to sell it. Or you're managing a property matter in Thailand from abroad and need someone you trust to sign on your behalf. This is one of the most common questions foreign nationals ask: can someone else handle this for me, and how do I make that legally binding?
The answer is a Power of Attorney (POA) — but in Thailand, a POA is not a one-size-fits-all document. Getting the form, the wording, and the certification steps right matters, especially for property transactions.
What a Power of Attorney Is Under Thai Law
A POA in Thailand is a form of agency, governed by the Civil and Commercial Code. Under Section 797, agency is a contract under which one person, called the agent, is authorized to act on behalf of another person, called the principal, and agrees to do so. As a general rule, acts properly carried out by an agent within the scope of the authority granted may bind the principal — though questions of scope, disclosure, and ratification can affect this in a given case.
Section 798 provides that where the underlying transaction is legally required to be made in writing, the appointment of an agent to carry out that transaction must also be made in writing; where the underlying transaction need only be evidenced in writing, the appointment of the agent must likewise be evidenced in writing. Because the sale, mortgage, transfer, and registration of rights in immovable property are subject to statutory formalities, a written POA — in the form accepted by the relevant Land Office — is normally required.
Sections 800 and 801 make the scope of authority especially important. An agent appointed for a specific matter (Section 800) generally has authority to carry out only what is necessary to complete that matter. A general grant of authority (Section 801) allows the agent to manage a wide range of matters on the principal's behalf, but does not automatically extend to certain significant acts — including selling or mortgaging immovable property, leasing immovable property for more than three years, making gifts, compromising disputes, filing a lawsuit, or submitting a dispute to arbitration. Specific authority is required for these. This is why a property POA should clearly identify the property, the transaction, and the exact powers granted.
Key Points to Know Before You Sign
General POA vs. Official Government Forms
A general, lawyer-drafted POA works for many everyday matters. However, several Thai government authorities have their own official forms for specific transactions:
- Land Department — for land and house transactions, the Department's own POA form, commonly known as Tor Dor 21 (ท.ด.21), is used; for condominium transactions, a separate condominium POA form, commonly known as Or Chor 21 (อ.ช.21), applies.
- Department of Business Development (DBD) — company incorporation and changes to registered particulars (directors, registered address, objectives, etc.) may require prescribed application forms, supporting documents, or a POA in the form the DBD accepts, depending on the specific filing and whether it's submitted on paper or electronically.
- Court proceedings — appointing a Thai lawyer to conduct litigation, authorizing someone to sign or file specific documents, and authorizing a representative to act for a company are each subject to their own procedural requirements. A property or general administrative POA should not automatically be assumed to cover court proceedings.
For Land Office registrations, using the Department's own form is strongly recommended. A general POA drafted independently — even by a lawyer — may be delayed or rejected if it doesn't contain the property details, witness requirements, or wording the Land Office expects.
Signing From Abroad: Certifying Your Signature
Where a POA is signed outside Thailand, the certification process depends on the receiving authority and the specifics of the situation. For a Land Department POA, the Department's own form states that a POA executed abroad should be certified by a Thai Embassy or Consulate, or by a notary public — this is generally an either/or requirement, not necessarily both steps performed one after the other.
In practice, however, the Land Office handling the registration may request additional evidence depending on the country of execution, the specific wording used, and how the notary's authority can be verified. The most reliable approach is to confirm the exact signing and certification instructions with the specific Land Office involved before signing, since requirements can vary by office and by country.
Stamp Duty
Powers of attorney (agency instruments) are subject to stamp duty under the Revenue Code's Stamp Duty Schedule. Under the current schedule, a specific-authorization instrument is generally subject to 10 baht in duty, while a general-authorization instrument is generally subject to 30 baht, with the principal as the party liable for the duty. Failing to pay the correct duty does not necessarily make the underlying authority void, but an insufficiently stamped instrument may not be admissible as evidence until the outstanding duty — and any applicable surcharge — has been paid. It is advisable to confirm the correct classification and rate for your specific document.
Specificity Protects Everyone
A POA that clearly names the exact property, the specific transaction (sale, mortgage, lease, etc.), and the precise authority granted is far less likely to be rejected — and far less likely to lead to disputes later. If the person you're appointing as agent will also be acting as the other party to the transaction, or will represent both sides, this needs to be expressly stated in the POA; Thai Land Department forms specifically require this kind of disclosure when it applies.

Frequently Asked Questions
Can I make a Power of Attorney for my Thai property while living abroad?
Yes. You can execute a POA in your country of residence, but it will generally need to have your signature certified — by a Thai Embassy/Consulate or a notary public, depending on the requirement — before it can be used for a property transaction in Thailand.
Will the Land Department accept a general POA drafted by my lawyer?
For property registration, the Land Department strongly prefers its own official form (such as Tor Dor 21 for land, or the condominium equivalent). A generic POA may be delayed or rejected if it lacks the required details or format.
Does the POA itself need to be translated into Thai?
Not necessarily. If the POA is completed on the Land Department's own Thai-language form, the POA itself may not need translation. However, supporting documents such as your passport, notarial certificate, or corporate documents may still need certified Thai translation, depending on the receiving office's requirements.
Is an Apostille accepted for a Power of Attorney used in Thailand?
Not as a substitute for the current certification process at this time. Thailand deposited its instrument of accession to the Apostille Convention on 30 June 2026, with the Convention scheduled to enter into force for Thailand on 28 February 2027. After that date, an Apostille may replace consular legalization for qualifying public documents between Thailand and other Contracting States — but whether and how this applies to a privately signed POA (which would typically need a notarial certificate first) will depend on implementing procedures still being finalized. It is advisable to confirm current requirements with the Department of Consular Affairs or with WPK.
What happens if my POA is worded too broadly?
A general POA does not automatically authorize significant acts like selling or mortgaging property, entering long-term leases, or filing lawsuits — these require specific authorization under Thai law. Vague wording can also lead to disputes later over what the agent was actually authorized to do. It's advisable to have the scope reviewed before signing.
Whether you're managing a property sale, a legal matter, or day-to-day affairs in Thailand while living overseas, getting your Power of Attorney right the first time saves significant time and hassle. If you'd like help reviewing your document, translating supporting materials, or understanding the certification process, we're here for you.
