Belgium Marriage Laws in 2026: Divorce and Inheritance

Getting married in Belgium does not automatically mean that everything you own belongs equally to your spouse. However, if you marry without a prenuptial agreement, Belgian law automatically applies a default marital property regime that determines how assets and income are treated.

These rules can have important consequences if you divorce or your spouse dies. They can affect your salary, savings, home, inheritance and even money held in a bank account under only one spouse’s name.

Understanding Belgium’s marital property rules is especially important for immigrants, business owners, homeowners and couples who maintain separate finances.

Here is how the system works in 2026.

What Happens If You Marry Without a Prenuptial Agreement in Belgium?

If you marry in Belgium without signing a prenuptial agreement, you automatically fall under the statutory marital property regime, unless another applicable legal arrangement governs your marriage.

Under this system, the couple’s assets are generally divided into three categories:

•  Your personal property.
•  Your spouse’s personal property.
•  The couple’s shared marital property.

This means that not everything automatically becomes jointly owned. Property acquired before marriage and certain inheritances or gifts generally remain personal assets, while income earned during the marriage and many assets acquired during the marriage generally belong to the shared estate.

The rules can be more complicated when assets are mixed, transferred between spouses or held in joint accounts.

1. The Default Marital Property Regime

The statutory regime is Belgium’s automatic arrangement for married couples who do not choose a different property regime.

Under this system, each spouse generally retains ownership of assets acquired before marriage, as well as qualifying inheritances and gifts received personally during the marriage.

However, the shared estate generally includes professional income earned during the marriage, savings accumulated from that income and many assets purchased during the marriage.

For example, suppose one spouse owns an apartment before getting married. The apartment generally remains that spouse’s personal property.

If the apartment generates rental income during the marriage, however, that income generally falls into the shared estate under the statutory regime.

The same principle can apply to salary deposited into a bank account held in only one spouse’s name. The name on the account does not automatically determine whether the money is personal or shared property.

These distinctions can become particularly important when a couple separates or one spouse dies.

2. What Happens to Separate Bank Accounts?

Having separate bank accounts does not necessarily mean that the money in those accounts belongs exclusively to the account holder.

Under Belgium’s statutory marital property regime, ownership depends on the source and legal classification of the money, not simply whose name appears on the account.

For example, if one spouse receives a salary and deposits it into a personal bank account, that income will generally still form part of the shared marital estate.

By contrast, money inherited personally by one spouse will generally remain that spouse’s personal property, provided its ownership and source can be established.

Keeping clear financial records is important. If personal funds are mixed with shared income or other assets, proving ownership may become more difficult.

Bank account ownership and marital property ownership are two different questions. A bank account holder may control the account without necessarily being the sole legal owner of every euro deposited into it.

3. What Happens to a Joint Bank Account?

A joint bank account can be useful for paying rent, mortgages, household bills and other shared expenses.

However, opening a joint account does not automatically make every asset owned by either spouse joint property.

Under the statutory regime, money in a joint account may be presumed to belong to the shared estate, but the circumstances and evidence can matter.

For example, if one spouse deposits inherited money into a joint account, the deposit may make it harder to demonstrate that the funds remain personal property.

Keeping inheritance documents, bank statements and records of transfers can help establish the origin of the money.

Couples should avoid assuming that the account name alone settles the legal question of ownership.

4. What Happens to Your Money in a Divorce?

When a married couple divorces, the division of assets depends heavily on the marital property regime.

Under Belgium’s statutory regime, the shared estate generally must be settled, while each spouse retains their personal assets, subject to the applicable legal rules and any claims between the spouses.

For example, savings accumulated from salaries earned during the marriage may form part of the shared estate even if the money is held in an account under one spouse’s name.

A home owned by one spouse before marriage generally remains personal property. However, the situation can become more complicated if marital funds were used to finance renovations, mortgage payments or other investments.

The outcome depends on the ownership documents, the source of the money and the applicable legal provisions.

Couples with businesses, investment portfolios, foreign property or substantial inheritances may need professional advice before agreeing to a financial settlement.

5. What Happens When a Spouse Dies?

The marital property regime also affects inheritance.

When a spouse dies, the marital property regime must generally be settled before the deceased person’s estate can be distributed.

Under the statutory regime, the surviving spouse generally retains their own share of the shared marital estate. The deceased spouse’s share, together with their personal property, forms part of the estate to be dealt with under inheritance law.

The surviving spouse’s inheritance rights then depend on the applicable succession rules, the existence of children or other heirs, and any valid will or marital agreement.

This means that the surviving spouse does not automatically inherit every asset simply because the couple was married.

Inheritance taxes may also apply. The amount depends on the applicable regional rules, the relationship between the deceased and beneficiary, and the assets involved.

Belgium’s inheritance tax rules differ between Flanders, Brussels and Wallonia, so the final tax bill can depend on the relevant region and circumstances.

6. Can You Choose a Different Marital Property Regime?

Yes. Couples can sign a prenuptial agreement through a notary to choose a different marital property regime or adapt the statutory regime.

Two major alternatives are separation of property and universal community of property.

Separation of Property

Under a separation-of-property regime, each spouse generally retains ownership of their own assets, income and savings.

This arrangement may appeal to people who want greater financial independence or who own a business and want to keep their financial affairs separate.

However, assets purchased together can still be jointly owned. The regime also does not automatically eliminate every possible financial claim or liability between spouses.

Universal Community of Property

Under a universal community regime, a much broader range of assets becomes shared property, including many assets acquired before marriage.

Specific exceptions may apply, and the agreement must be structured according to the applicable law.

This regime can have significant consequences for property ownership, debts, divorce and inheritance. Couples should obtain notarial advice before choosing it.

7. Can You Sign a Marriage Contract After Getting Married?

Yes. Married couples in Belgium can generally change their marital property regime through a notary.

For example, a couple that initially married under the statutory regime may later decide to adopt separation of property or make other permitted changes.

This can be particularly relevant if one spouse starts a business, receives a substantial inheritance, buys property or experiences a major change in financial circumstances.

The appropriate arrangement depends on the couple’s objectives, assets, debts and family situation.

8. Why the Name on a Bank Account Is Not Enough?

One of the most common misunderstandings is that the person whose name appears on a bank account automatically owns all the money in it.

In reality, three separate questions may need to be answered:

Who legally owns the money?

Who is authorized to manage or withdraw it?

How will the money be classified if the marriage ends through divorce or death?

These questions do not always have the same answer.

A spouse may have access to an account without owning all its funds. Likewise, money held in a personal account may form part of the shared marital estate under the statutory regime.

Keeping documentation for inheritances, gifts, property purchases and major transfers can help reduce disputes.

What Should Married Couples in Belgium Do?

If you are married or planning to marry in Belgium, consider the following steps:

•  Find out which marital property regime applies to your marriage.
• Keep records of assets owned before marriage.
• Maintain documentation for inheritances and personal gifts.
•  Understand how salaries and savings are treated under your regime.
•  Seek notarial advice before buying property together or investing substantial personal funds.
• Review your arrangements if you start a business or experience a major financial change.
•  Consider inheritance planning if you want to protect your spouse or children.

A notary can explain the available options and prepare a marriage contract where necessary.

Frequently Asked Questions

What happens if you marry in Belgium without a marriage contract?

The statutory marital property regime generally applies automatically. It separates each spouse’s personal assets from the shared marital estate.

Is money in a personal bank account shared after marriage in Belgium?

Not necessarily all of it, but the account being in one spouse’s name does not make every deposit personal property. Salary earned during marriage generally belongs to the shared estate under the statutory regime.

Does my spouse automatically inherit everything if I die in Belgium?

No. The outcome depends on the marital property regime, inheritance law, other heirs and any valid estate-planning arrangements.

Can I protect an inheritance from being divided in a divorce?

An inheritance received personally generally remains personal property under the statutory regime. Keeping clear records of its origin and avoiding undocumented mixing with shared funds can help establish ownership.

Can married couples in Belgium change their property regime?

Yes. Couples can generally change their regime through a notary, subject to the applicable legal requirements.

Belgium’s marital property rules can have a major impact on savings, bank accounts, real estate and inheritance. The absence of a prenuptial agreement does not mean that all property automatically belongs equally to both spouses, but it does mean that the statutory regime generally determines how assets and income are classified.

The most important lesson is that account ownership, property ownership and inheritance rights are not the same thing.

Understanding these rules before a divorce, property purchase or inheritance dispute can help couples make informed financial decisions and avoid unnecessary conflicts.
