Certificate of prenatal acknowledgment

Prenatal acknowledgment of a child takes place before birth. It creates a bond of paternity or co-maternity between a person and a child.

The prenatal acknowledgment certificate is a certificate issued by a Civil Status officer which proves this link of paternity or co-maternity.

The requested document must have been drawn up or transcribed in Belgium, or filed with the Federal Public Service for Foreign Affairs before 2004.
