According to the Belgian Nationality Code, a child born abroad is Belgian if he or she is: 

  • born of a Belgian parent born in Belgium; 
  • born of a Belgian parent, born abroad (outside Belgium) who has made a declaration within 5 years of the birth, claiming Belgian nationality for his or her child. 

In other words :

  • if the father or mother is Belgian and was born in Belgium, the child has Belgian nationality by right, without any other formality (in this case, please proceed with the registration of a new-born child);
  • if the father or mother is Belgian but neither of them was born in Belgium, a Declaration of Attribution of Belgian Nationality must be made before the child reaches the age of five. Only the Belgian parent can sign the Declaration of Attribution.
