Divorce law is complex, especially with international elements. The information below is intended to give you an overview so you can have an informed conversation with a qualified Thai family lawyer. Do not take legal action based on this guide alone.
Nobody moves to Phuket thinking they'll need a divorce lawyer. But marriages end — and when they do in Thailand, the process is different enough from Western systems that expats are often caught completely unprepared, especially around property rights, visa status and custody across borders.
This guide covers how divorce works in Thailand, what the key issues are for foreign nationals, and where to find legal help in Phuket.
- Two routes: consensual (administrative) or contested (court)
- Consensual divorce can be completed at an Amphur office in one day
- Contested divorce: typically 6 months to 2 years
- Marital property (sin somros) split 50/50 by default
- Marriage visa (Non-O) holders must change visa after divorce
- Child custody: Thai courts prioritise the child's best interests
- Foreign divorces may need Thai court recognition to be valid in Thailand
How Divorce Works in Thailand
Thai law under the Civil and Commercial Code (CCC) recognises two types of divorce:
1. Consensual (Administrative) Divorce
If both parties agree to divorce and have no disputes over property, children, or financial arrangements, the process is straightforward. Both spouses visit the local district office (Amphur) with two witnesses, sign the divorce registration (Por Ror 6), and the divorce is registered the same day.
Requirements: original marriage certificate, both Thai ID cards or passports, two Thai witnesses, and a prior agreement on any assets or custody. If the marriage was registered in Thailand, this is the simplest and least expensive route.
2. Contested (Judicial) Divorce
If one spouse refuses to divorce or parties can't agree on property, child custody, or maintenance, the case goes to the Family Court. Thai law lists specific grounds for divorce including adultery, desertion, imprisonment, physical abuse, and failure to provide maintenance.
Contested divorce typically takes 6 months to 2 years and requires Thai legal representation. Phuket's Family Court handles cases for the province.
Property Division in Thai Divorce
Thai law distinguishes between three types of marital property:
| Property Type | Thai Term | Division on Divorce |
|---|---|---|
| Personal property owned before marriage | Sin suan tua | Stays with original owner |
| Property inherited or gifted during marriage | Sin suan tua | Stays with recipient |
| Property acquired during marriage | Sin somros | Divided 50/50 by default |
| Property of disputed origin | — | Presumed to be sin somros |
Foreign property complications
The most complex situations arise when:
- Property is held in a Thai company structure (often used by foreign buyers to hold land)
- Condos are registered in a foreign spouse's name under the foreign quota
- Assets are held outside Thailand and subject to different national laws
- Property was purchased using funds from overseas that are hard to trace
This is not an area to navigate without a specialist Thai family and property lawyer. Property held in a Thai company structure in particular requires careful legal analysis.
Child Custody in Thailand
Thai courts follow the principle of the child's best interests when determining custody. Both parents have parental rights unless a court rules otherwise. "Sole custody" (the most common arrangement) gives one parent the right to make major decisions; "joint custody" (less common in Thai courts) involves shared decision-making.
International custody issues
Cross-border custody is one of the most serious challenges in expat divorces. If one parent wishes to leave Thailand with a child after divorce, they need written consent from the other parent (if the other parent has parental rights) or a court order. Thailand is a signatory to the Hague Convention on International Child Abduction, but enforcement is inconsistent. Get legal advice before making any decisions about travel with children during or after divorce proceedings.
Visa Implications of Divorce for Phuket Expats
This is often the most pressing practical concern for expats living in Phuket on a marriage-based visa.
If your Thai residence is based on a Non-Immigrant O (Marriage) visa, your legal right to stay in Thailand ends when the marriage ends. You need a new visa basis before or very shortly after the divorce — don't wait until you're overstaying or under pressure. Phuket Immigration on Phuket Road can advise, or engage a visa agent now.
Alternative visa options after divorce include:
- Non-OA (Retirement Visa) — if you're over 50 and meet the financial requirements (฿800,000 in a Thai bank or ฿65,000/month income). See the Non-OA retirement visa guide.
- LTR Visa — Long-Term Resident visa for high-earners, retirees or remote workers. See the LTR visa guide for Phuket.
- DTV (Digital Nomad Visa) — for remote workers. See the DTV visa guide.
- Non-B (Business/Work) — if you're employed or running a business in Thailand.
Divorce Costs in Phuket: What to Budget
| Type of Divorce | Legal Fees (est.) | Court/Admin Fees | Timeline |

| Contested (simple) | ฿80,000–฿150,000 | ฿5,000–฿15,000 | 6 months – 1 year |
| Contested (complex/property) | ฿150,000–฿400,000+ | ฿15,000–฿50,000+ | 1–3 years |
| International recognition (addl.) | ฿20,000–฿80,000+ | Varies by country | 3–12 months |

Recognising a Foreign Divorce in Thailand
If you were married and divorced in another country, Thailand may not automatically recognise that divorce as valid within Thai jurisdiction. This matters if you later wish to remarry in Thailand, need to update property registrations, or have any legal matters where marital status is relevant.
To have a foreign divorce recognised in Thailand, you generally need to apply to a Thai court with certified, notarised and Apostilled copies of the foreign divorce decree, translated into Thai. Your embassy or the Thai lawyers' registration body can point you to qualified translators. For Apostille requirements, see the Phuket apostille document guide.

- Thai Lawyers Council registration (Bar membership)

- If on a marriage visa, start exploring alternative visa options immediately.
- Document all marital assets and their origins before proceedings begin.
- If children are involved, understand the rules around travel and custody before anyone leaves Thailand.
- If married abroad, check whether your divorce will need separate Thai court recognition.
