When a couple gets married, one of the most common legal questions is:

Which assets are considered marital property, and which remain personal property?

This issue becomes particularly important in cases involving divorce, property division, inheritance planning, or disputes between spouses.

This article summarizes the key principles under the Thai Civil and Commercial Code in a straightforward and practical way.

1. Property Acquired Before Marriage Is Personal Property

Any property that a person legally owns before registering the marriage is considered personal property (Sin Suan Tua).

The property remains the exclusive ownership of that spouse even after the marriage.

Examples

• A house purchased and transferred before marriage.
• A vehicle purchased before marriage.
• Savings accumulated before marriage.

These assets remain personal property.

2. Personal Property Remains Personal Even If It Changes Form

Selling or exchanging personal property does not change its legal status.

If personal property is converted into another asset, the new asset generally remains personal property, provided its origin can be proven.

Examples

• Selling a personal vehicle and using the proceeds to purchase a condominium.
• Selling inherited land and investing the money in shares.

If the owner can trace the source of the funds, the replacement asset remains personal property.

3. Income Generated from Personal Property Is Generally Marital Property

Although the original asset is personal property, the income or fruits derived from that property during the marriage are generally regarded as marital property (Sin Somros).

Examples include:

• Rental income
• Bank interest
• Dividends
• Other income generated after the marriage

4. Property Acquired During Marriage Is Generally Marital Property

As a general rule, any property acquired during the marriage is marital property, regardless of:

• Which spouse earned the income;
• Which spouse paid more; or
• Whose name appears on the receipt or payment records.

Examples

• Salary
• Bonuses
• Business income
• Houses purchased during marriage
• Vehicles purchased during marriage

Unless an exception applies, these assets are considered marital property.

5. Personal Effects and Professional Tools May Be Personal Property

Certain items acquired during marriage may still qualify as personal property if they are:

• Personal clothing
• Eyeglasses
• Professional equipment
• Tools necessary for one’s occupation

Examples include:

• A doctor’s medical instruments
• A lawyer’s legal reference materials
• A carpenter’s tools

However, the value of such items must be reasonable in light of the couple’s financial status. Excessively valuable items may be treated differently depending on the circumstances.

6. Inheritance Received as a Legal Heir Is Personal Property

Property inherited because a person is a lawful heir remains that person’s personal property.

The other spouse generally has no ownership rights over inherited assets.

7. Engagement Gifts Are Personal Property

Under Thai law, engagement property belongs exclusively to the bride and is classified as her personal property.

8. Gifts Received Without Consideration Are Personal Property

Property received as a gift is generally classified as personal property.

Examples include:

• Money
• Land
• Houses
• Vehicles
• Jewelry

Exception

If the donor expressly states that the gift is intended to become marital property, it will be treated accordingly.

9. Property Received Under a Will Is Personal Property

Assets inherited through a will are generally regarded as personal property.

Exception

If the testator clearly specifies in the will that the asset is to become marital property, it will be treated as such.

Key Legal Principles

1. The Date Ownership Is Acquired Matters

Thai law focuses on the date legal ownership is obtained, not:

• when the purchase agreement was signed;
• when installment payments began; or
• when the loan was fully repaid.

The date ownership legally transfers is the decisive factor.

2. If It Cannot Be Proven, the Property Is Presumed to Be Marital Property

Where it is impossible to distinguish whether an asset is personal or marital property, Thai law presumes it to be marital property.

The spouse claiming that the asset is personal property bears the burden of proving it.

Practical Examples

Example 1

A car is purchased under a hire-purchase agreement before marriage, but ownership transfers after the marriage.

Legal result:

The vehicle is generally considered marital property, because legal ownership was acquired during the marriage.

Example 2

A spouse obtains a bank loan and purchases a car before marriage, with ownership transferring immediately, although loan repayments continue after marriage.

Legal result:

The vehicle remains personal property, because ownership was acquired before marriage.

Example 3

Salary, rental income, interest, and dividends earned during the marriage.

Legal result:

These are generally regarded as marital property.

Quick Summary

Acquired before marriage → Personal Property

Acquired during marriage → Generally Marital Property

Important Exceptions

• Inheritance
• Engagement gifts
• Gifts received without consideration
• Property received under a will
• Certain personal effects and professional tools

Three Rules to Remember

If you remember these three principles, you’ll be able to analyze most property issues under Thai family law:

“Look at the date ownership was acquired. Property acquired during marriage is generally marital property. If ownership cannot be clearly distinguished, the law presumes it to be marital property.”
