California Codes, Civil Code - CIV, Division 3 — Obligations, Part 2 — Contracts, Title 5 — Extinction of Contracts, Chapter 3 — Modification and Cancellation, Section 1697
A contract not in writing may be modified in any respect by consent of the parties, in writing, without a new consideration, and is extinguished thereby to the extent of the modification.
Notes
Allows parties to a contract that is not in writing to modify it in any respect by giving written consent, without new consideration. The written modification extinguishes the prior contract to the extent of the modification, so its effect reaches the original agreement only to that stated extent.
