Separation of Assets in a Thai Divorce: Sin Somros and Sin Suan Tua

Last updated on August 7, 2026

Separating assets for a divorce in Thailand is one of the most important and sensitive parts of the process. Whether you are married to a Thai citizen or a foreigner, knowing how Thai law divides property is important. This guide explains the key legal principles, processes, and tips to help you protect your interests, including separation of assets for a divorce in Thailand.

The classification of marital and personal property is introduced in our overview of family law in Thailand.

Legal Basis for Separation of Assets in Thailand

Under the Thai Civil and Commercial Code, there are two main types of property. These are used for asset separation in a divorce in Thailand

Personal Property (สินส่วนตัว / Sin Suan Tua)

This include, according to section 1471 of the Civil Code:

• Assets owned before the marriage
• Personal gifts or inheritance
• Tools or equipment used for a profession
• Khongman gifts (traditional Thai engagement gifts)

Personal property remains with the person who owns it and is not divided during divorce. According to Section 1472, if someone sells or exchanges personal property, they still own the replacement or money.

Marital Property (สินสมรส / Sin Somros)

When discussing asset division in a divorce in Thailand, it’s important to understand two types of property. These are personal property and marital property. Common property, according to section 1471 and 1474 of the Civil Code, includes:

• Property acquired during the marriage
• Gifts or inheritance expressly declared as marital property
• Income generated from personal property

Marital property is usually divided equally between spouses during a divorce. This is stated in Section 1533 of the Civil and Commercial Code.

Table: Personal vs Marital Property

In divorce cases in Thailand, the law helps separate marital property fairly.

Property Type	Description	Divided Upon Divorce?
Sin Suan Tua	Owned before marriage, personal gifts, inheritance	No
Sin Somros	Acquired during marriage, income from personal property	Yes

The Separation Process

Step 1: Identify and Document Assets

Each spouse must disclose all personal and marital property. Supporting documents like bank records, title deeds, or invoices help establish ownership and value.

Step 2: Asset Valuation

Professional appraisals may be needed for real estate, businesses, or valuable personal property. Assets without proper documentation may be presumed to be Sin Somros.

Step 3: Negotiation or Mediation

Many couples reach agreements without court. Mediation or lawyer-assisted negotiation can help avoid long and costly disputes.

Step 4: Court Resolution (if no agreement)

If no agreement is reached, a Thai family court will divide marital assets based on:

• Length of the marriage
• Financial and non-financial contributions
• Each spouse’s needs and conduct

A judge may award unequal shares in exceptional cases, especially if one party misused or concealed property.

Special Situations

Prenuptial Agreements

A legally valid prenuptial agreement (สัญญาก่อนสมรส) can define which property remains personal. Courts in Thailand will usually enforce such agreements if they are fair and registered before marriage.

Debts and Liabilities

Debts incurred for family purposes or during the marriage are generally shared. However, personal debts used for gambling or affairs may not be.

Businesses and Companies

If one spouse owns a company or shares, valuation and division can be complex. Courts may consider who contributed to business growth, even indirectly.

Foreign Assets

Thai courts generally do not divide foreign property, but it must be disclosed. You may need lawyers in other countries to secure your share abroad.

What to Do When Your Spouse Gives Marital Assets Away

One of the most common things we see before a divorce filing is not a hidden account — it is a gift. Money moved to a partner. A car put in a sibling’s name. A condo signed over to a parent “for safekeeping.” Thai law has a specific remedy for this, and it has a deadline that most people miss.

File early — waiting costs you twice

This is the single most important point on this page, so it goes first.

Under CCC section 1480, an action to revoke an unauthorised dealing with marital property is barred:

• one year after you learn of the grounds for revocation; and
• ten years after the transaction itself, in any event.

The one-year clock starts when you find out — not when you separate, not when you file for divorce, and not when you finally decide to do something about it. Discovering a transfer and then spending eight months deciding whether to act can extinguish the claim outright.

There is a second, less obvious cost to waiting, confirmed by the Supreme Court in Decision 139/2569: a gift of marital property remains valid until a court revokes it. That means the recipient is not in default until judgment, and interest on the money only starts running from the date of the judgment — not from the date the money left the account. In that case, a wife recovered THB 1,431,731 in full but lost roughly two years of interest on it, purely because of timing.

When can a gift of marital property be revoked?

CCC section 1476 lists the dealings with sin somros that spouses must manage jointly or with the other’s consent. Subsection (5) covers gratuitous gifts (hai doy sanaeha / ให้โดยเสน่หา). A gift made by one spouse alone is revocable unless it clears a narrow two-part exception. The gift must be both:

• for charitable purposes, for social purposes, or made in accordance with moral obligation; and
• proportionate to the family’s station in life.

This is frequently misstated as four separate exceptions, which would let any gift through so long as it was proportionate to the family’s means. It does not work that way — a gift must satisfy both limbs. A temple donation of a sensible size is covered. A customary family wedding gift is covered. A seven-figure transfer to a romantic partner fails both.

The third-party defence — and why it usually fails against a gift

Section 1480 protects a third party who received the property in good faith and for value. Both limbs are required. Because a gift by definition has no consideration, the recipient of a gift cannot rely on this protection no matter how innocent they were. This is why revocation claims against a gift recipient are considerably stronger than claims against a buyer.

The practical consequence: if your spouse sold the asset to a genuine arm’s-length buyer, your claim is likely against your spouse, not the asset. If your spouse gave it away, the asset itself is recoverable.

Two separate claims — and you can run both

Where the transfer went to a romantic partner, two distinct claims arise, and they are often confused:

Claim	Provision	What it recovers	Against whom
Revocation of the gift	CCC s.1480 (with s.1476)	The property or money itself	The recipient
Compensation	CCC s.1523 para 2	Damages for the marital wrong	The third party

Decision 139/2569 settled an important procedural question here: settling one does not bar the other. The Supreme Court held that a concluded section 1523 compensation claim is not a repeat proceeding under CPC section 144, because the two claims rest on different grounds. You can run them in sequence.

But note the interaction with the limitation period. If you settle the compensation claim first and the section 1480 one-year clock has been running the whole time, you may win the first case and lose the right to bring the second. Sequence them deliberately, not by accident.

What to do, in order

1. Date your discovery. Write down when you learned of the transfer and how. This is the fact the one-year limitation period turns on, and you may have to prove it.
2. Preserve the evidence. Bank statements, transfer slips, Land Department records, chat messages, photographs of the asset. Get these before accounts are closed or access is cut off.
3. Do not ratify. Section 1480 removes your right to revoke if you have ratified the transaction. Avoid anything that reads as approval after the fact — signing consent documents, accepting a share of the proceeds, written acknowledgements. Decision 139/2569 confirms that avoiding the transaction is not ratifying it, but do not create the argument in the first place.
4. Get the injunction question answered early. If further dissipation looks likely, provisional measures to freeze the asset are worth considering before, not after, the next transfer.
5. File the section 1480 claim promptly — ahead of, or alongside, any compensation claim.

If you have just discovered a transfer, the clock is already running. Speak to our family law team before the one-year period under section 1480 closes.

Foreigners and Mixed-Nationality Marriages

If one spouse is a foreigner, international law may apply to movable property. However, Thai law governs land and immovable property in Thailand. Thai family courts say that foreigners cannot own land in Thailand. They can only hold it through a valid structure, like a lease or usufruct.

In cases involving foreigners, our divorce lawyer in Bangkok can help ensure compliance with both Thai and international law.

Non-Married Couples

For unmarried couples who bought property together, marital property law does not apply. Instead, you may need to pursue a civil case for co-ownership or partnership dispute resolution.
