To this point, we have been considering the assignment of the assignor’s rights (usually, though not solely, to money payments). But in every contract, a right connotes a corresponding duty, and these may be delegated. A delegation is the transfer to a third party of the duty to perform under a contract. The one who delegates is the delegator. Because most obligees are also obligors, most assignments of rights will simultaneously carry with them the delegation of duties. Unless public policy or the contract itself bars the delegation, it is legally enforceable.
In most states, at common law, duties must be expressly delegated. Under Uniform Commercial Code (UCC) Section 2-210(4) and in a minority of states at common law (as illustrated in Assignment Includes Delegation , Rose v. Vulcan Materials Co.), an assignment of “the contract” or of “all my rights under the contract” is not only an assignment of rights but also a delegation of duties to be performed; by accepting the assignment, thedelegatee (one to whom the delegation is made) implies a promise to perform the duties. (See Figure 14.3)
