Nationality lawyer

Altea's lawyers specialising in Belgian immigration law are also experts in all matters concerning Belgian nationality.

There are several legal paths to acquiring Belgian citizenship. Out-of-date information sometimes circulates on the Internet and can be the source of confusion and even error. Municipal governments may also provide general information which does not necessarily correspond exactly to individual situations or recent developments in jurisprudence.

Current legal texts such as the nationality code, and therefore the law, or its royal execution decree, are regularly revised. They are completed by an administrative circular. Its contents can, on certain points, contradict the other texts. The interpretation of these legal texts also evolves according to the interpretations by the Royal Prosecutor and the jurisprudence.

Do you meet the requirements to submit a declaration of Belgian nationality? Do you have the right to request naturalisation? Will your children automatically become Belgian? It’s useful to verify the legal basis of your request and to ensure that your file is actually complete. The competent departments within municipal governments can sometimes offer you advice, but it's often a good idea to ask the opinion of a specialist lawyer. Often, a simple consultation during a single meeting will allow you to pursue your case on your own without difficulty.

If you have been refused Belgian citizenship, you may have to consider submitting an appeal. In such cases, the deadlines are very short. A specialist lawyer can guide you regarding the opportunity for an appeal and, if applicable, assist and represent you in such a situation.

In other cases, you could be required to justify your right to reacquire Belgian nationality. An individual may also discover that they were recognised as a Belgian citizen due to an error by the authorities.

Lastly, you could be facing deprivation of citizenship.

Specific rules and procedures apply to each situation. They must sometimes be interpreted within the scope of the fundamental rights.

Nationality law is constantly evolving and many case law decisions make this matter even more complex. Therefore, your lawyer's advice is often a welcome aid.

Altea offers advice by expert lawyers, adapted to your personal situation.
