The obligations resulting from acts performed by the protected person less than two years before publicity of the judgment opening the protective measure may be reduced on the sole proof that his inability to defend his interests, as a result of the alteration of his personal faculties, was notorious or known to the co-contractor at the time when the acts were performed.
These acts may, under the same conditions, be annulled if it can be shown that the protected person has suffered prejudice.
By way of derogation from Article 2252, the action must be brought within five years of the date of the judgment opening the measure.
