Nobody moves to Phuket thinking they'll need this guide. But after six years watching the expat community here, I can tell you that a significant number of couples who arrive together leave separately — or at least navigate a Thai legal system neither of them expected to deal with. Divorce in Thailand has specific quirks for foreigners, and understanding them early (ideally before it comes to it) is genuinely useful.

This guide is general information, not legal advice. For your specific situation, you need a Thai family lawyer. I'll point you toward how to find one in Phuket at the end.

Quick facts — Divorce in Phuket 2026

  • Two routes: uncontested (Amphoe, fast and cheap) or contested (court, slow and expensive)
  • Uncontested divorce requires mutual agreement on all terms
  • Thai marital property (sin somros) is split 50/50 by default
  • Marriage visa (Non-O) is immediately affected by divorce
  • Child custody: court awards based on best interests of child
  • International cases (foreign nationals) can be complex — get advice early

Route 1: Uncontested Divorce at the Amphoe

If both parties agree to divorce and agree on all the terms — division of assets, child custody, and any alimony — you can register the divorce directly at the Amphoe (district office) in Phuket, exactly where you registered the marriage. This is called karasuam nai amphoe (administrative divorce).

The process requires both parties to appear in person with two witnesses (Thai nationals preferred). You need a written mutual agreement on all terms, signed and witnessed. There is essentially no cost — no court fees, and you only pay a lawyer if you choose to have one draft the agreement. Most straightforward uncontested divorces are completed within a day. You leave with a Thai divorce certificate (Kor Ror 6).

This route is only available if: (a) you married in Thailand at the Amphoe, and (b) both parties are in full agreement on all terms. If there is any disagreement on assets or children, you need the court route.

Route 2: Contested Divorce Through the Thai Courts

If you and your spouse cannot agree on terms, or if one party is refusing to cooperate, you need to file a petition with the Thai Family Court. In Phuket, this is the Phuket Provincial Court (ศาลจังหวัดภูเก็ต) on Phang Nga Road in Phuket Town.

Thai law recognises specific grounds for divorce under Section 1516 of the Civil and Commercial Code. The most commonly used grounds by expats include:

  • Adultery by either party
  • One party supporting another person as a spouse or lover
  • Malicious desertion for one year or more
  • Physical or mental cruelty, including serious insults to honour or dignity
  • Unsound mind (declared by court) for three consecutive years
  • Breach of financial maintenance obligations
  • Separation by agreement for three or more years

Contested cases are genuinely lengthy and expensive. Expect 6 months to 2+ years for resolution. Legal fees depend heavily on complexity: THB 50,000 for simple cases, THB 200,000–500,000 or more for contested assets and custody battles. The psychological toll is also significant in a small island community where everyone knows everyone.

Property Division in a Thai Divorce

Thai law distinguishes between two types of property in a marriage:

Sin suan tua (personal property): Assets owned before the marriage, or received as personal gifts or inheritance during the marriage. This is returned to the original owner and is not subject to division.

Sin somros (marital property): Assets acquired by either party during the marriage — income, investments, property purchased during the marriage (regardless of whose name it's in). This is divided equally (50/50) between the parties by default.

The critical issue for many Phuket expats: property held in a Thai spouse's name. During marriage, many foreign nationals hold a long-term lease on a property while their Thai spouse holds the freehold title. On divorce, the freehold is marital property (sin somros) if it was purchased during the marriage — even though the foreign national can never own it. This means the Thai spouse receives their 50% of the freehold value as their personal share. The foreign national's 50% of the marital estate is calculated from all marital assets combined.

A prenuptial agreement (prenup) can clarify these arrangements before marriage. If you're getting married in Thailand and there are significant assets involved, a prenup registered at the Amphoe at the time of marriage is strongly recommended. See our getting married in Phuket guide for details on the registration process.

Contested (Family Court)6 months–2+ yearsTHB 50,000–500,000+Irreconcilable disputes on assets or custody

Child Custody in Thailand

Thai courts determine child custody based on the best interests of the child (ผลประโยชน์สูงสุดของเด็ก). In practice, the considerations include:

  • The child's age (younger children tend to be placed with the mother)
  • Each parent's financial stability and ability to provide
  • The child's existing living arrangements and school continuity
  • The child's own expressed preference (for older children)
  • Any history of abuse, neglect, or instability

Joint custody is possible and increasingly common in cases where both parents remain in Phuket. If one parent is a foreign national wishing to relocate children abroad, the court will scrutinise this carefully. Parental abduction is a serious concern in international divorce cases — courts can and do impose exit restrictions on children during custody proceedings.

If you are a foreign national in a custody dispute, get a Thai family lawyer immediately. Do not wait to see how things develop.

⚠ Visa impact: Marriage visa holders

If your current visa is a Non-Immigrant O (marriage) visa, divorce will affect your legal right to remain in Thailand. You must switch to a different visa category before your next extension. Options include the retirement visa (50+, THB 800,000 deposit), Thailand Elite, LTR, or DTV. Contact a Phuket immigration agent as soon as divorce proceedings begin — do not wait until your extension is due. See our full visa guide for current options and requirements.

Finding a Family Lawyer in Phuket

Phuket has a surprisingly good legal sector given its size. Several law firms in Phuket Town and Chalong specifically handle expat family law. When choosing a lawyer:

  • Ask specifically about experience with international divorce cases
  • Request a fee estimate in writing before engaging
  • Be cautious of firms that promise quick outcomes or guarantees in contested cases
  • Your embassy may have a list of recommended lawyers — the British Embassy Bangkok maintains one, as does the US Embassy

Initial consultations typically cost THB 1,500–3,000 and last 45–60 minutes. Use this to assess whether you feel comfortable with the lawyer's communication and understanding of your situation.

International Divorce: When One Party Isn't in Thailand

If one spouse has already left Thailand, the process is more complex. For uncontested divorce, both parties normally need to be physically present at the Amphoe — although there are provisions for power of attorney in limited circumstances. For contested cases, the court can proceed with proper notice to a party overseas, but enforcement of Thai court orders internationally varies by country.

Some expat couples who married in Thailand choose to divorce in their home country where procedural law is more familiar, especially if there are no Thai assets to divide. The Thai Kor Ror 3 (marriage certificate) is recognised in most Western countries for this purpose. However, the Thai Amphoe will still need to be notified of the foreign divorce decree for the Thai civil register to be updated — this requires an authenticated and translated copy of the foreign divorce decree.

Frequently Asked Questions

Can a foreigner divorce in Thailand if they married abroad?

Yes, if you are domiciled in Thailand and your marriage is legally recognised. However, many expats find it simpler to divorce in their home country if both parties have connections there. The Thai civil register still needs updating regardless of where the divorce occurs.

How much does divorce cost in Thailand?

An uncontested Amphoe divorce is essentially free (minimal legal fees if you use one). A contested court divorce costs THB 50,000–500,000+ depending on complexity. Asset disputes and child custody battles are at the expensive end. Allow 6 months to 2+ years for contested cases.

How is property divided in a Thai divorce?

Thai law divides marital assets (sin somros — property acquired during the marriage) equally 50/50. Personal property brought into the marriage (sin suan tua) stays with the original owner. Property in a Thai spouse's name is generally considered marital property unless protected by a prenuptial agreement.

What happens to child custody in a Thai divorce?

Thai courts award custody based on the best interests of the child. Younger children typically placed with the mother. Courts are cautious about international relocation of children — court approval is required if one parent wants to take children abroad permanently. A family lawyer is essential for any contested custody situation.

Does divorce affect my visa status in Phuket?

Yes, if you hold a Non-Immigrant O (marriage) visa. Divorce affects your legal right to extend this visa. Switch to another visa category before your next extension date. Options include the retirement visa, Thailand Elite, LTR, or DTV. Seek visa advice from a Phuket immigration agent as soon as divorce proceedings begin.
