Obtain Power of Attorney in Thailand

A power of attorney in Thailand represents an instrument that enables authority for one individual to act on another person’s behalf, used for different transactions like real estate ones. The individual who provides the authority is named the principal or grantor, and the one who receives it, the agent or attorney-in-fact.

The applicable legislation in Thailand rules that both the Grantor and the Agent are in capacity and can also grant and execute the authorized acts as prescribed in the power of attorney. Our law firm in Thailand can offer guidance on this matter and can help you obtain the power of attorney in Thailand.

Types of power of attorney in Thailand

There are two types of power of attorney in Thailand:

•  the general power of attorney (GPA): it has a higher scope and duration;
•  the special power of attorney (SPA): it has a limited scope and duration.

Who can execute a power of attorney in Thailand?

According to the local legislation, a power of attorney in Thailand can be executed only by individuals who are legally competent to do so. In plus, the power of attorney has to be in compliance with formal and substantial fundamentals as stated by the law in order to be valid and enforceable, like being notarized after being signed by both the grantor and the agent.

Conditions to grant a power of attorney in Thailand

Before drafting a Thai power of attorney, there are certain requirements to be met. These are:

• both the agent and the donor must be adults, have full mental capacities, and be able to complete the elements stated in the power of attorney;
• the power of attorney must be correctly written and must comply with the legal requirements applicable to such documents;
• where the case requires, the power of attorney must also be notarized.

The last requirement applies with buying a property in Thailand, for example. If the real estate is purchased through a proxy, the power of attorney in a notarized form must be filed with the Land Registry along with the identification papers of the principal.

Things to consider when preparing an official power of attorney in Thailand

When organizing an official power of attorney in Thailand, consider the following aspects:

•  clearly point out the type of property which is about to be transferred, e.g., land title, house, building, and so on. Our lawyers in Thailand can provide more information on this matter;
•  noticeably mention the subject of the power of attorney, by mentioning exactly the agent’s empowered actions, such as purchasing, mortgaging, or selling. In case there are any distinct conditions, these should be stated;
•   writing or typing should be effected with the same instrument;
•   in case there are any changes, fill-ins or cross-outs, they have to be written stating the exact modifications which have been made and the principal has to put his or her signature next to each occurrence;
•   there has to be minimum one witness to the signatures;
•   in case the power of attorney is made outside the country, it will necessitate a certification from a Thai embassy or consulate, or a notary public.
