Delegation is a term used in the law of contracts to describe the act of giving another person the responsibility of carrying out the performance agreed to in a contract. Three parties are concerned with this act - the party who had incurred the obligation to perform under the contract is called the delegator; the party who assumes the responsibility of performing this duty is called the delegatee; and the party to whom this performance is owed is called the obligee.
