Limitation for investigation of suits for declaration

A suit for investigation into paternity or maternity may only be instituted during the life-time of the purported parents, save for the following exceptions: 1. If the parents expire during the minority of the children, because, in this case, they have the right to institute the suit, even after the death of the parents, provided they do it before the expiry of four years from their emancipation or majority; 2. If the child obtains, again, a document written and signed by the parents, in which these reveal their parenthood; because, in this case, they may file the suit at any time when they find the said document; without prejudice to the general rules regarding prescription of assets.
