FAQ

What is the difference between common law and UCC contract law?

Common law governs contracts for services, employment, and real estate, while the Uniform Commercial Code (UCC) governs contracts for the sale of goods. The distinction is crucial because the rules for formation, modification, and enforcement differ significantly between the two systems.

What is the mailbox rule in contract law?

The mailbox rule, established in Adams v Lindsell (1818), provides that acceptance of an offer is effective upon dispatch (posting) rather than upon receipt by the offeror. This rule applies to acceptances communicated by mail, fax, or email, provided the acceptance is properly addressed and sent.

What is promissory estoppel?

Promissory estoppel is a doctrine that allows enforcement of a promise without consideration when the promisor should reasonably expect the promise to induce action or forbearance, and the promisee relies to their detriment. The Restatement (Second) of Contracts § 90 provides for promissory estoppel as a substitute for consideration.

What is the Statute of Frauds?

The Statute of Frauds requires certain contracts to be in writing to be enforceable, including contracts for the sale of land, surety contracts, contracts that cannot be performed within one year, and contracts for the sale of goods over $500 (UCC 2-201). The original Statute of Frauds, enacted in England in 1677, has been adopted in various forms in common law jurisdictions.
