Paternity issues

The task of a Child Welfare Officer is to investigate the paternity of extramarital children.

After the child is born, the Child Welfare Officer will send the mother an invitation to a paternity test.

Usually, the parents visit the Child Welfare Officer together, but the mother also has the option to launch the paternity investigation process by herself. The man who believes himself to be the father, may also launch the investigation by acknowledging the child as his own.

When investigating paternity, the Child Welfare Officer will hear both the mother and the man believed to be the father. DNA tests are also possible. Both the mother and the man have to prove their identity when visiting the Child Welfare Officer, through a reliable method (valid identity card or a passport).

If the man is not willing to voluntarily acknowledge the child, the Child Welfare Officer can, upon the mother's request, take legal actions, in order to confirm the paternity in a court of justice.
