1. A waiver of the defense of the barring of a claim by the lapse of time shall not be valid before the right to invoke such defense is established, nor may it be agreed that a claim shall not be admissible after a period other than that specified by law. 2. Any person who has the capacity to dispose of their rights may expressly or impliedly waive the defense after the right to invoke it has been established, provided that such waiver shall not be enforceable against creditors if it is made to their detriment.
