Summary

An adult who was born in Belgium and has legally resided there since birth can acquire Belgian nationality by declaration. This is one of the five adult declaration categories described by FPS Justice. It is different from the narrower rules under which some children are automatically Belgian at birth.

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.

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.

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.

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 civil-status 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.
