What Are Liquidated Damages in a California Contract?

A liquidated damages clause fixes, at the time of contracting, the amount one party will owe if it breaches, sparing everyone the cost and uncertainty of proving actual damages later. Construction contracts use per-day delay amounts; purchase agreements use deposit forfeitures; commercial leases and service contracts use them for early termination.

California's default rule, in Civil Code section 1671, makes liquidated damages provisions in commercial contracts valid unless the challenging party proves the amount was unreasonable under the circumstances existing when the contract was made. The core test is whether the figure was a reasonable estimate of anticipated harm or an in terrorem penalty designed to punish breach; penalties are unenforceable. Consumer contracts flip the presumption, and residential purchase deposits have their own rules capping forfeitures.

Litigation over these clauses focuses on the negotiation record: what harm the parties anticipated, how the number was derived, and whether one-way clauses or stacked remedies push a provision into penalty territory. A defensible file made at drafting time is the best insurance the clause will hold.
