(1) If the obligor has performed any juristic act which has a property right for its subject, with the knowledge that it would prejudice the obligee, the obligee may apply to the court for its revocation and restitution of its original status; provided, this shall not apply where a person who has derived a benefit from such act or a subsequent purchaser was, at the time of the act or of the purchase, unaware of the fact that it would prejudice the obligee.
(2) The action mentioned in the preceding paragraph shall be brought within one year from the time when the obligee became aware of the cause for revocation, or within five years from the time when the juristic act was done.
