The person placed under court protection retains the exercise of his or her rights. However, he or she may not, on pain of nullity, perform any act for which a substitute decision-maker has been appointed pursuant to Article 437.
The acts he has performed and the commitments he has entered into during the period of the measure may be rescinded for simple injury or reduced in the event of excess even though they could be annulled under article 414-1. In particular, the courts take into consideration the usefulness or uselessness of the transaction, the size or consistency of the protected person’s assets and the good or bad faith of those with whom they have contracted.
An action for nullity, rescission or reduction belongs only to the protected person and, after his death, to his heirs. It is extinguished by the five-year period provided for in article 2224.
