In contract law, delegation (Latin intercessio) is 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. The term is also a concept of Administrative Law.
A delegation will be null and void if it poses any threat to the commercially reasonable expectations of the obligee. For example, a task requiring specialized skills or based on the unique characteristics of the promisee can not be delegated. If a specific celebrity was hired to make a speech, they could not delegate the task to another person, even if the other person would give the same speech, word for word. However, a delegation of performance that does not pose such a threat will be held to be valid. In such a case, the obligee will be under an affirmative duty to cooperate with the delegatee to the extent necessary for the fulfillment of the delegator's obligations
If the delegatee fails to perform satisfactorily, the obligee may elect to treat this failure as a breach of the original contract by the delegator or may assert himself as a third party beneficiary of the contract between the delegator and the delegatee, and can claim all remedies due to a third party beneficiary.
If the delegation is without consideration, the delegator remains liable for nonperformance, while the delegatee will not be liable to anyone for anything. Unlike an assignment, a delegation is virtually always for consideration, and never donative - few people are going to accept the charitable offer to perform a task contracted to someone else.
A parallel concept to delegation is assignment, which occurs when one party transfers his present rights to receive the benefits accruing to the assignor under that contract. A delegation and an assignment can be accomplished at the same time, although the right to sue for nonpayment always stays with delegator. Under the common law, a contract clause prohibiting assignment also prohibits delegation. Another common law rule requires that a party to a contract can not delegate performance that involves special skills or reputation (although it is possible to have a novation under such circumstances).
