Code § 1698: Under California law, a contract in writing may be modified by: (a) a contract in writing; (b) an oral agreement to the extent it is executed by the parties; or (c) an oral agreement supported by new consideration. Even when a contract contains a NOM clause, California courts have permitted oral modifications through the doctrines of estoppel, oral novation, waiver, and independent collateral contracts. This written Amendment eliminates ambiguity and is the recommended approach.

7.2 Statute of Frauds — Cal. Civ. Code § 1624

NOTE: If the Agreement as modified falls within the California Statute of Frauds (e.g., contracts for the sale of real property, agreements not to be performed within one year, contracts for goods over $500), this Amendment must be in writing and signed by the party to be charged. This written, signed Amendment satisfies that requirement.

☐ The Agreement, as amended, ☐ may / ☐ may not be further modified orally.

About This Template

A contract is a written record of what two or more parties agreed to and what happens if someone does not follow through. Clear language, defined terms, and clean signature blocks keep disputes small and enforceable. The most common mistakes in contracts come from vague promises, missing details about timing or payment, and skipping standard protective clauses like governing law and dispute resolution.
