Addictio In Diem Law and Legal Definition

Addictio in diem is a Latin term which means “assignment for a fixed period” or “postponement to a date.” As used in Roman law, it is a clause in a contract of sale, whereby the parties agree that within a given time, if the seller can find a person who will make him/her a better offer than the original purchaser, the contract can be rescinded. In addictio in diem, it is sufficient for the first buyer to offer as much as the party who bids.
