Power of attorney in Thailand
A power of attorney in Thailand is not the document most foreigners think they are signing.
What is a power of attorney in Thailand?
Powers of attorney here fall under the agency provisions of the Civil and Commercial Code. An agency is an arrangement for getting a specific thing done: someone acts in your name, within limits you set, on a transaction you have identified.
Within that scope it works. It is a transactional instrument, not a standing grant of authority.
When does a Thai power of attorney end?
An agency is extinguished by the death, incapacity or bankruptcy of either party. Not suspended. Extinguished.
So the document most Western expats assume covers them if they have a stroke, a serious accident or a dementia diagnosis is the one document that stops working at precisely that moment.
Is there a durable power of attorney in Thailand?
No. In the UK, Australia and the United States there is an instrument that survives incapacity: a lasting power of attorney, an enduring power of attorney, a durable power of attorney. Different names, same idea. You appoint someone while you are competent, and their authority continues after you are not.
Thai law has no equivalent, whatever your nationality and however long you have lived here.
A power of attorney made in your home country is not a reliable substitute either. What weight, if any, a foreign lasting power of attorney carries in Thailand is not something this site will assert without a Thai lawyer's confirmation.
What replaces it if you lose capacity?
A court process, run by somebody else, after the fact.
Where a person can no longer manage their own affairs, a court may adjudge them incompetent and appoint a guardian, or place them under curatorship. It is two applications and two hearings, and reported timelines start at three months.
Nothing you sign in advance produces this outcome. You cannot nominate your guardian the way you would nominate an attorney at home. Somebody has to apply, and a court decides who is appointed on a best-interests standard.
What happens to the bank account and the bills in the meantime is on if you lose capacity rather than die.
Do the medical powers of attorney sold by Thai law firms work?
Not answered yet, and this site will not pretend otherwise.
Thai law firms sell lawyer-drafted bilingual medical powers of attorney, and have done for well over a decade. That sits awkwardly against everything above. Either those documents operate differently from ordinary agency, or they carry less weight than the name suggests. The question is with a Thai lawyer.
Until it is answered: if you hold one, keep it. Do not assume it is enough, and do not build a plan around it alone. This page will be updated with the answer and the date it was given.
What can you do instead?
- A living will. Section 12 of the National Health Act gives any person in Thailand, including foreigners, the right to refuse treatment that merely prolongs the terminal stage of life. Narrow, but it can be made by you alone.
- Marriage, where it is available and acceptable to you. It puts a spouse at the top of the list of people who may apply to the court, and makes them next of kin for medical purposes.
- A Thai will, professionally drafted. It does nothing while you are alive, but it removes a separate problem from the pile. See what a Thai will does and does not cover.
- Telling people in advance. A partner who knows to expect a three-month court process behaves very differently from one who finds out at a hospital desk.
