The deliberations of the family council are null and void where they have been surprised by fraud or deceit or where substantial formalities have been omitted.
Nullity is covered by a new deliberation valid as confirmation according to article 1182.
An action for nullity may be brought by the tutor, the subrogated tutor, the other members of the family council and the public prosecutor within two years of the deliberation, as well as by a minor who has reached majority or is emancipated within two years of coming of age or becoming emancipated. The statute of limitations does not run if there has been fraud or deceit as long as the fact giving rise to it has not been discovered.
Acts performed by virtue of an annulled deliberation may be annulled in the same way. However, the time limit runs from the act and not from the deliberation.
