Formalities after marriage in Belgium

After getting married in Belgium, it is important to complete several formalities so that all changes are officially recorded and taken into account in various documents. These steps are important for both Belgian citizens and foreign citizens who get married in the country.

Amending documents (passport, residence permit, insurance policies).
After registering your marriage, you need to update your personal documents. The first thing you need to do is amend your passport or identity card. To do this, you need to provide a marriage certificate, which is issued by the municipality or commune after registration. You will also need to pay a fee, which varies depending on the municipality.

For foreign nationals, if they already have a residence permit in Belgium, it is necessary to contact the local immigration office to update the information on marital status in their documents. Since marriage can affect the residence status, it is important that this information is up to date.

Another important step is updating your insurance policies. If you or your spouse have health insurance or other types of insurance, you will need to notify your insurer of your marital status. This is necessary to ensure that benefits, premiums, and other insurance policies are properly processed. It is also important to notify your employer of your new status, as this may affect your tax liability.

Marriage registration at the consulate or embassy of your country (for foreigners).
Foreign citizens who marry in Belgium must register their marriage at the consulate or embassy of their country. This is a mandatory step in order for the marriage to be recognized in their home country and to be formalized in accordance with the laws of their country. To register a marriage, you must provide the original marriage certificate issued in Belgium, as well as other documents that may be required depending on your country of origin (e.g. proof of citizenship or place of residence).

The registration process varies by consulate or embassy, and often requires that the marriage certificate be translated into the consulate’s official language. It is recommended to check in advance for all requirements and consulate working hours, as well as possible processing times.

Notifying your employer or tax authorities of a change in marital status.
If you work in Belgium, it is important to notify your employer of a change in marital status. This is necessary to ensure that your tax liability is calculated correctly and that you can claim any tax deductions that apply. In Belgium, tax rates may generally vary depending on the number of dependents and marital status. Your employer should provide you with updated tax forms or notifications.

It is also important to notify the tax authorities, as your marital status may affect your tax return. If you have recently changed your status, you will need to submit updated information to the Federal Tax Service. This can be done online or in person, depending on the situation.

In addition, if children are born in a marriage, this also requires notification to the tax authorities for inclusion in the system of social payments and tax benefits.

Completing all the formalities after marriage in Belgium is an important step to ensure that your documents and status are properly completed and taken into account by all relevant institutions. Following these procedures will help avoid legal complications and ensure a smooth transition to a new life, taking into account all the rights and obligations associated with marriage.
