(1) A party may perform his or her duty through a delegate unless otherwise agreed or unless the other party has a substantial interest in having his or her original promisor perform or control the acts required by the contract. No delegation of performance relieves the party delegating of any duty to perform or any liability for breach.

(2) Unless otherwise agreed all rights of either seller or buyer can be assigned except where the assignment would materially change the duty of the other party, or increase materially the burden or risk imposed on him or her by his or her contract, or impair materially his or her chance of obtaining return performance. A right to damages for breach of the whole contract or a right arising out of the assignor’s due performance of his or her entire obligation can be assigned despite agreement otherwise.

Terms Used In Missouri Laws 400.2-210

  • Attachment: A procedure by which a person's property is seized to pay judgments levied by the court.
  • Contract: A legal written agreement that becomes binding when signed.
  • Damages: Money paid by defendants to successful plaintiffs in civil cases to compensate the plaintiffs for their injuries.
  • Injunction: An order of the court prohibiting (or compelling) the performance of a specific act to prevent irreparable damage or injury.
  • Jurisdiction: (1) The legal authority of a court to hear and decide a case. Concurrent jurisdiction exists when two courts have simultaneous responsibility for the same case. (2) The geographic area over which the court has authority to decide cases.
  • Obligation: An order placed, contract awarded, service received, or similar transaction during a given period that will require payments during the same or a future period.

(3) The creation, attachment, perfection or enforcement of a security interest in the seller’s interest under a contract is not a transfer that materially changes the duty of or increases materially the burden or risk imposed on the buyer or impairs materially the buyer’s chance of obtaining return performance within the purview of subsection (2) of this section unless, and then only to the extent that, enforcement actually results in a delegation of material performance of the seller. Even in that event, the creation, attachment, perfection and enforcement of the security interest remain effective, but (i) the seller is liable to the buyer for damages caused by the delegation to the extent that the damages could not reasonably be prevented by the buyer, and (ii) a court having jurisdiction may grant other appropriate relief, including cancellation of the contract for sale or an injunction against enforcement of the security interest or consummation of the enforcement.

(4) Unless the circumstances indicate the contrary a prohibition of assignment of “the contract” is to be construed as barring only the delegation to the assignee of the assignor’s performance.

(5) An assignment of “the contract” or of “all my rights under the contract” or an assignment in similar general terms is an assignment of rights and unless the language or the circumstances (as in an assignment for security) indicate the contrary, it is a delegation of performance of the duties of the assignor and its acceptance by the assignee constitutes a promise by him or her to perform those duties. This promise is enforceable by either the assignor or the other party to the original contract.

(6) The other party may treat any assignment which delegates performance as creating reasonable grounds for insecurity and may without prejudice to his or her rights against the assignor demand assurances from the assignee (section 400.2-609).
