This lesson explores the contours of anticipatory repudiation, including the repudiating promisor's ability to retract his repudiation, the nonrepudiating promisee's right to demand adequate assurances of performance, and the effect of the promisor's repudiation on the promisee's obligation to perform.

This lesson deals with the problem created by the Battle of the Forms. At common law, the mirror image rule requires an acceptance to be exactly like the offer. The rule is reversed under the Uniform Commercial Code, however. Under UCC § 2-207, an acceptance is still an acceptance even though it states different or additional terms from the offer. This lesson will explore the effect of such different or additional terms and when they are operative.

Traditional contract law classifies contracts into bilateral and unilateral contracts. Bilateral contracts are those involving promises made by all parties, whereas unilateral contracts involve promises made by only one of the parties. This lesson explores the distinction between bilateral contracts (where both parties make promises) and unilateral ones (where only one party makes a promise) and the effect on the obligations of the parties resulting from the classification. This lesson ends with an analysis exercise on unilateral and bilateral contracts.
