Any person who has acquired any of the debtor’s assets through a legal act subject to avoidance is obliged to return them. The consideration must be reimbursed to the extent that it is still in the hands of the debtor or the debtor has been enriched by it. Otherwise, reimbursement may only be claimed as a debt due by the debtor.
If the legal act subject to avoidance consisted in the repayment of a debt, the debt shall be reinstated upon restitution of the amount received.
The bona fide recipient of a gift is only obliged to make restitution up to the amount of his enrichment.
