Section 1555: The seven grounds on which legitimation may be claimed in court

English translation

In an action for legitimation, the child is presumed to be the legitimate child of the man if any of the following facts appears: 1. Where there is a rape, abduction or illegal confinement of the mother during the period when conception could have taken place; 2. Where there has been elopement or seduction of the mother during the period where conception could have been taken place; 3. Where there is a document emanating from the father and acknowledging the child as his own; 4. Where it appears in the birth register that the child is his child, with evidence that the father notified the birth or knew of and consented to the notification; 5. Where there has been open cohabitation of the father and the mother during the period where conception could have been taken place; 6. Where the father had sexual intercourse with the mother during the period when conception could have been taken, and there are grounds to believe that he or she is not the child of another man; 7. Where there has been a continuous common repute of being a legitimate child. Their status resulting from continuous common repute of being a legitimate child is established by means of facts showing the relationship of father and child, as evidenced by the child’s connection with the family to which he claims to belong, such as the fact that the father has provided the child’s education or maintenance, or that he has allowed the child to use his family name or other facts. In any of the above cases, if it appears that the man cannot be the father of the child, the action shall be dismissed.
