1. If the subject of the right is an act, and its nature or the terms of the agreement require the debtor to perform it in person, the creditor may refuse performance by any other person. 2. If the debtor fails to perform the act, the creditor may request the court's authorization to have it performed, and may also perform it without permission in case of necessity. In both cases, the performance shall be at the debtor's expense. 3. The court's judgment shall take the place of performance if the subject of the right is an act, and its nature so permits.
