If the mother is married when she gives birth, the husband is automatically presumed to be the father of the child; he does not need to officially acknowledge paternity. Even if another man claims to be the biological father of the child, the husband’s relationship as legal father overrides and it is necessary to file a petition contesting paternity to change this state of affairs.
When a father-child relationship has been established by the non-married father recognising the child, this relationship may be challenged by filing a petition to dispute paternity.
The following persons may file a petition:
The competent court is the court in the place of residence of one of the parties involved, namely the child, the mother or the alleged father (or his own parents following his death).
In both cases a petition may be filed within a year of the day on which the petitioner learns that the child has been recognised and that the person recognising the child is perhaps not the biological father. A petition must be filed within five years of recognition.
The child may also challenge recognition before he or she reaches the age of 19.
The competent court is court in the place of residence of one of the parties involved.
When a petition or challenge is approved, the father-child relationship is withdrawn along with all its related effects, including name, citizenship and parental authority. The court which issued the decision notifies the civil register authorities so that the entry in the civil register can be changed.
