Phuket Expat Legal Checklist 2026: Wills, POA & Contracts
Here's the thing nobody tells you when you move to Phuket: the practical legal paperwork is the boring part of expat life, but it's the part that matters most when things go wrong. I've seen expat families in Phuket face genuine crises — a death, a coma, a relationship breakdown, a property dispute — that would have been manageable with proper documentation, but were instead catastrophic without it.
This checklist covers the legal documents every expat living in Phuket should either have already or actively be working towards. It's not everything a lawyer would cover, but it's the foundation.
The Phuket Expat Legal Checklist
1. Thai Will (Phinnai)
If you have any assets in Thailand — a bank account, a condo, a car, shares in a company — you need a Thai will. Your home-country will has no automatic standing in Thai courts. Without a Thai will, your assets enter Thai probate court: an expensive, slow process that requires heirs to be physically present in Thailand. A basic Thai will costs 5,000–15,000 THB through a Phuket law firm. If you own property, expect 10,000–25,000 THB.
2. Power of Attorney (POA) — Thai Version
A Thai power of attorney authorises a named person to act on your behalf for specific legal and administrative tasks. Essential if you travel frequently, own property, or need someone to handle your TM30 reporting, contract signing, or visa renewals during absence. A specific POA (limited to defined acts) is generally safer than a general POA. Cost: 3,000–8,000 THB through a Phuket solicitor. See our detailed guide on power of attorney in Thailand.
3. Reviewed and Translated Rental Contract
Many Phuket rental contracts are written in Thai, or in dual-language format where the Thai text is legally controlling. Before signing, have the Thai version reviewed by a qualified bilingual lawyer — not just Google Translated. Key clauses to verify: deposit terms and return conditions, maintenance responsibilities, termination rights for both parties, what happens if the property is sold during your lease, and whether pets or subletting are permitted. Cost for contract review: 3,000–8,000 THB.
4. Certified Copies of Key Documents
Keep certified copies of your passport (not just the original), marriage certificate, birth certificates of all family members, and any property chanote (title deed) or condo title you hold. Certified copies should be notarised — either at your home country's consulate in Bangkok (British Embassy, German Embassy, Australian Embassy etc.) or by a Thai notary. Cost: typically 500–2,000 THB per document. Digital certified copies are increasingly accepted but check requirements for each use case.
5. Estate Planning for Thai-Held Assets
Beyond a will, expats with significant Thai assets should consider how those assets are structured. Condo units can be directly bequeathed to heirs. Company shares (if you hold property through a Thai company) need a succession plan. Joint accounts are easier to handle than sole accounts after death. A basic estate planning consultation with a Phuket property lawyer costs 3,000–10,000 THB and is worth every baht for anyone with meaningful Thai assets. See our estate planning guide for Phuket expats.
6. Employment or Business Contract (if working)
If you're employed in Thailand, you should have a signed, Thai-compliant employment contract that specifies salary, benefits, termination conditions, and your employer's obligations regarding your work permit. If you run your own business, your company registration documents, shareholder agreements, and director roles should be formally documented. Many expats operating informally in Thailand face serious problems if a business relationship breaks down without proper documentation.
7. Vehicle Ownership Documentation
If you own a car or motorbike in Phuket, the vehicle should be properly registered in your name (or a trusted name if you don't have a long-term visa that allows vehicle ownership). Keep the blue book (tabian rot), insurance documents, and your international or Thai driving licence accessible. If your motorbike is registered in a Thai owner's name (common when buying second-hand), have a signed purchase receipt and chain of ownership documentation — even informally — in case of disputes.
8. Healthcare Directives (Advanced Care Directive)
This one is almost universally ignored by expats until it matters. An advanced care directive (or living will) specifies your wishes regarding medical treatment if you become incapacitated. Bangkok Hospital Phuket and Siriroj Hospital can advise on their specific requirements. This doesn't need to be an elaborate document — a signed, witnessed statement of your medical preferences, held by your next of kin and with the hospital, is a significant step.

Documents From Your Home Country That Phuket Life Requires
Several ongoing administrative situations in Phuket require documents from your home country — either originals or certified copies. It's worth knowing what you might need before you need it urgently:
- Marriage certificate: Required for dependent visa applications, joint bank accounts, and next-of-kin documentation at hospitals.
- Birth certificates of children: Required for school enrolment at both Thai government and international schools, and for adding children to visas.
- Police clearance certificate: Required for some long-stay visas (Retirement, LTR) and for teaching work permits. These must be current (usually within 3 months of application) — don't assume the one from when you arrived is still valid.
- Medical clearance certificate: Required for Retirement visa and some other long-stay applications.
- Pension or income evidence: Required for Retirement visa annually.
Thinking About a Thailand Elite or LTR Visa for Long-Term Security?
If the annual visa renewal process frustrates you, Thailand Elite and Long-Term Resident visas offer 5–20 year stays with minimal annual requirements. We can connect you with vetted visa agents who handle the full application.

These are the ones I've seen cause the most preventable problems over six years of watching the Phuket expat community navigate difficult situations:
No Thai will: The most common — and most damaging — omission. A Thai bank account can be frozen for months without a will. A condo can be tied up in probate court for years. It costs 10,000 THB to prevent this. Do it.
Oral rental agreements: Any rental arrangement longer than three years that isn't in a written contract registered at the Land Department is legally unenforceable in Thailand. Even for shorter leases, verbal agreements leave you with no recourse if the landlord decides to sell, renovate, or simply change the terms.
Vehicle not properly insured: Compulsory motor insurance (Por Ro Bor) covers third parties but provides minimal compensation. Comprehensive insurance is strongly recommended for any vehicle you rely on. See our car insurance guide and motorbike insurance guide.
Healthcare proxy not designated: If you're hospitalised and unconscious, Thai hospitals will contact whoever is listed as your emergency contact — but they have no legal obligation to follow that person's medical wishes unless a formal directive exists.
