Belgian Citizenship for People Raised There

Belgium Citizenship
Pathway overview

At a glance

If you are an adult who was born in Belgium and has lived there legally since birth, you may qualify for citizenship by making a formal declaration. This differs from the rules that automatically make some children Belgian. You must prove continuous legal residence and have the required status when applying.

Who can apply
Adults born in Belgium who have lived there legally since birth
Current residence status
An unlimited right to remain in Belgium is required when filing
Filing
Make a nationality declaration before the local civil registrar

Summary

Adults born in Belgium who have lived there lawfully since birth can apply for Belgian citizenship through a specific declaration procedure. The municipality must verify the entire residence history and the unlimited right to remain at filing. A Belgian birth record alone cannot establish either condition.

Unlike several other adult declaration categories, this category does not add separate language, social-integration or work-participation tests. The key issue is often whether every period meets the nationality law's residence rules. If the person already became Belgian under a childhood rule, they instead need evidence of that existing nationality.

Eligibility

The core requirements are:

The commune also checks whether the file is complete and whether any serious personal facts create a legal obstacle. It sends an admissible file to the royal prosecutor, Immigration Office, and State Security for the required opinions.

More about this route

The applicant must be at least 18, have their main residence in Belgium, and have an unlimited right of residence when filing. The Belgian commune verifies both the continuous legal-residence history and the current residence status.

The official adult-declaration overview does not add separate language, social-integration, or economic-participation tests to this born-and-resident-since-birth category. The difficult issue is often proving that the residence was legally continuous from birth, especially where registrations, residence cards, or time abroad create gaps.

FPS Justice currently shows a €1,000 federal fee for acquisition procedures, paid before the declaration, plus possible costs for records, translations, and copies. Because the fee is indexed by law, verify the current amount immediately before payment.

The adult declaration depends on legal residence since birth
  1. Birth in Belgium Establish the Belgian birth Obtain the full birth record and the beginning of the Belgian residence history.
  2. Birth through the present Document legal residence throughout Have the commune examine the complete history, including any gap, deregistration, or time abroad.
  3. Adult application File the adult nationality declaration At 18 or older, confirm Belgian main residence and an unlimited right to stay before filing.

Birthplace alone is insufficient for this category. If nationality already arose under a childhood rule, the correct task is to document that existing status instead.

What This Route Allows

Once the declaration is accepted and entered in the records, the applicant becomes Belgian. They can obtain Belgian citizen identity and passport documents, no longer need an immigration permit to live or work in Belgium, and gain EU citizenship rights.

Belgium permits more than one nationality. The applicant should still check the law of any other country of nationality for its rules on voluntary acquisition.

What This Route Is Not

This is not automatic citizenship for every person born in Belgium. If an automatic childhood rule applied, the right task is to document existing nationality. If the applicant did not legally reside in Belgium continuously from birth, another five- or ten-year declaration category may be relevant instead.

It is also not enough to have lived in Belgium socially or physically while lacking the residence status required by the Nationality Code. The commune's legal-residence calculation controls.

At filing, the applicant must be an adult and hold an unlimited right to stay. For a route requiring language knowledge, a willingness to learn later is insufficient; accepted social-integration evidence can also establish language knowledge under the official rules.

Next Steps

  1. Obtain the full Belgian birth record.
  2. Ask the commune for a historical residence extract covering birth through the present.
  3. Have the commune identify any gap, deregistration, short-stay status, or period abroad before assuming the category is met.
  4. Confirm that the current residence right is unlimited, not merely that the residence card itself has not expired.
  5. Gather identity and birth, marriage, and other family records in the exact form the commune requests.
  6. Confirm the current indexed federal fee and pay it using the official method before filing.
  7. Make the declaration before the civil registrar and retain the acknowledgment showing when the complete file entered the four-month prosecutor review period.
