A husband may deny paternity in court within six months of becoming aware of facts constituting reasonable doubt that they are the father of a child born to a wife. However, they may file a petition to deny paternity no later than six years after the birth of the child. The mother may deny that the child’s father is her husband within six months of the child’s birth.
If a child is born before the 160th day after the date of marriage, it suffices if the mother’s husband denies paternity for him to be presumed not to be the father of the child. This does not apply if the mother’s husband had sexual intercourse with the child’s mother during the period between the 160th and the 300th day before the child’s birth, or if he knew, when entering into marriage, that she was pregnant.
If a subsequent husband has denied their paternity of a child of a remarried woman, the six-month time limit to deny the paternity of the previous husband starts to run on the day following the date on which the previous husband learned of the decision.
Paternity may not be denied with respect to a child born at a period between the 160th day and the 300th day after artificial insemination was carried out with the consent of the mother’s husband, or with the consent of another man if the mother is not married, regardless of the genetic substance used. This does not apply if the child’s mother became pregnant in a different manner.
A man whose paternity has been determined by the mutual consent of the parents may deny paternity of a child only if it is not possible that he could be the father. He may deny paternity within 6 months of the date on which paternity was so determined. If paternity is determined before the birth of the child, the period will not end earlier than 6 months after the birth of the child. Within the same time limits, the mother of the child may deny that the father of the child is the man whose paternity has been determined by a mutual declaration of consent of the parents.
If the petition for denial of paternity is made after the expiry of the set time limit, a court may decide to forgive the delay if the best interests of the child and public order so require.
