Divorce & Separation in Phuket
The Foreigner's Guide to Thai Family Law

By Phuket Expat Guide Last updated: March 2026 ~3,400 words

Not every expat relationship works out. When a marriage ends in Phuket — whether between two foreigners or in a mixed Thai-foreign couple — the legal process is more straightforward than most people expect, but it comes with specific complications around assets, visa status, and children. This guide covers what you need to know.

⚠ Legal disclaimer This guide provides general information about Thai divorce law. It is not legal advice. Every situation is different. Hire a qualified Thai family lawyer before making decisions. Thai family law can surprise even experienced practitioners.

Two Routes to Divorce in Thailand

Route 1: Divorce by Mutual Consent

The simpler, faster, and cheaper route. Both spouses agree on all terms — asset division, child custody, spousal support — and register the divorce at the Amphoe district office. In Phuket: Amphoe Mueang Phuket, 3 Narisara Road, Phuket Town.

Both parties must be physically present. The divorce is registered in the Thai civil register and is legally effective immediately. A Thai divorce certificate (ทะเบียนการหย่า / Khor Ror 6) is issued.

✓ Get a lawyer even for uncontested divorce Even if you agree on everything, hiring a lawyer to draft the divorce agreement (฿15,000–฿30,000) ensures it is properly worded, captures all asset agreements correctly, and is legally enforceable. The amphoe will register whatever document you present — it won't check whether the agreement protects your interests.

Route 2: Contested Divorce by Court Order

If spouses cannot agree on divorce itself or on terms, one party must file a petition at the Phuket Provincial Court. The Thai Civil and Commercial Code specifies the legal grounds for contested divorce. The process takes 6 months to several years depending on complexity.

GroundNotes
Adultery (wife's)Husband can divorce. Wife must prove husband "supports" another woman.
Support of another womanWife can divorce if husband supports and honours another woman as a wife.
Serious harm or mental tortureEither party can use this ground.
Desertion for 1+ yearEither party. Must prove genuine abandonment.
Separation for 3+ yearsEither party. No fault required if living apart 3 consecutive years.
Imprisonment for 1+ yearImprisonment for offence not committed jointly.
Dangerous communicable diseaseMust be incurable and pose risk to the other spouse.
Insanity for 3+ yearsNot likely to recover; creates impossible cohabitation.

How Assets Are Divided in Thai Divorce

Thai law distinguishes between two types of marital property:

Asset typeThai termWho keeps it
Jointly acquired marital assetsสินสมรส (Sin somros)Divided equally (50/50) on divorce
Pre-marital personal assetsสินส่วนตัว (Sin suan tua)Each spouse keeps their own
Gifts received during marriageGenerally sin suan tuaKept by the recipient spouse
Inheritance receivedSin suan tua if clearly separateKept by inheriting spouse

What Counts as Sin Somros?

Any asset acquired during the marriage is presumed to be marital property unless proven otherwise. This includes: property purchased during marriage, business earnings, savings accumulated during marriage, investment returns on marital assets.

⚠ Property purchased in a Thai spouse's name If land or a house was purchased in your Thai spouse's name during the marriage (which is common since foreigners cannot own land), that property is technically in their name but is marital property subject to 50/50 division in divorce. However, the practical enforcement of this against a determined Thai spouse who controls the title deed can be very difficult. This is where proper legal advice is essential — ideally before the marriage breaks down.

Condominiums and Foreign-Owned Property

Condominium units held in a foreigner's name (within the 49% foreign quota) are subject to the normal marital asset rules — they are sin somros if purchased during the marriage and should be divided 50/50. The foreigner can retain ownership of their 49% quota unit — but may owe their spouse 50% of its value.

Business Interests

Businesses established during the marriage are generally marital property. Company shares, goodwill, and business assets acquired during marriage are subject to 50/50 division unless pre-marital business interests can be clearly separated. Mixed situations are common and require careful legal analysis.

What Divorce Means for Your Visa Status

This is the section many expats overlook until it's too late. If your Thai visa was based on marriage to a Thai national, divorce ends that visa basis.

Visa typeEffect of divorceAction needed
Non-O (marriage to Thai)Visa basis ends. Cannot renew on marriage grounds.Apply for new visa basis immediately. Options: Non-OA retirement (if 50+), DTV, Thailand Elite, Non-B.
Non-O (parent of Thai child)Unaffected — basis is parentage, not marriage.Ensure child registration remains current.
Retirement visa (Non-OA)Unaffected — basis is age/income, not marriage.No immediate action needed.
DTV / Thailand EliteUnaffected — independent visa types.No action needed.
Work permit holder (Non-B)Unaffected if work permit remains valid.Notify employer; ensure work permit status unchanged.
⚠ Act on your visa immediately after divorce Do not wait until your current visa extension expires. Change your visa basis as soon as divorce proceedings begin. Running out of legal status in Thailand during an already stressful divorce compounds the problem enormously. See our complete visa guide for alternatives.

Divorce should not mean deportation. Our recommended visa agents in Phuket can advise on your best legal-stay option before your current visa basis ends.
