§ 2311 Contract Performance Specifications

This law says a sales contract is still okay even if some details are left for one side to decide later, as long as those details are set honestly and reasonably.

Key Takeaways

  • •A contract stays valid even if some performance details are left for one party to fill in later.
  • •The buyer usually decides what mix of goods they want; the seller usually decides how the goods will be shipped, unless they agree otherwise.
  • •If a party doesn’t give needed details on time, the other side can pause their work or treat the delay as a breach.

Example

A buyer agrees to buy 200 tables, but the exact colors and delivery date are left for the seller to pick later.

The contract is still good. The seller must choose the colors and set a delivery date in good faith and in a way that makes business sense. If the seller drags their feet, the buyer can pause their own duties or treat the seller’s delay as a breach.

§ 2311 Contract Performance Specifications

(1) An agreement for sale which is otherwise sufficiently definite (subdivision (3) of Section 2204) to be a contract is not made invalid by the fact that it leaves particulars of performance to be specified by one of the parties. Any such specification must be made in good faith and within limits set by commercial reasonableness. (2) Unless otherwise agreed specifications relating to assortment of the goods are at the buyer’s option and except as otherwise provided in subdivisions (1)(c) and (3) of Section 2319 specifications or arrangements relating to shipment are at the seller’s option. (3) Where such specification would materially affect the other party’s performance but is not seasonably made or where one party’s co-operation is necessary to the agreed performance of the other but is not seasonably forthcoming, the other party in addition to all other remedies (a) Is excused for any resulting delay in his own performance; and (b) May also either proceed to perform in any reasonable manner or after the time for a material part of his own performance treat the failure to specify or to co-operate as a breach by failure to deliver or accept the goods. (Enacted by Stats. 1963, Ch. 819.)
