Under California law, establishing the existence of a valid contract requires proving three fundamental components that demonstrate a “meeting of the minds” between the parties. These building blocks are essential for any successful breach of contract claim:

1. Offer: One party must communicate a serious proposal in a way that a reasonable person would understand it as such.
2. Acceptance: The other party must provide an unequivocal acceptance of that proposal. Under the “mirror image rule,” the acceptance cannot introduce new terms; it must match the offer exactly.
3. Consideration: There must be a bargained-for exchange of value between the parties. This can include money paid, services performed, or even a promise to refrain from doing something.

In California, contracts may be written, oral, or implied by conduct. While written contracts are easier to enforce because terms are clearly documented, oral contracts are also valid. However, proving an oral contract requires corroborating evidence such as emails, text messages, invoices showing partial performance, or witness testimony.

Additionally, for a contract to be enforceable, the parties must have a “meeting of the minds” supported by mutual consideration. Without these specific elements, a court will find that no valid contract was formed in the first place.
