Stop Notice (Stop Payment Notice)

A stop notice (stop payment notice in California usage) is a remedy aimed at the money rather than the land: where a mechanics lien encumbers the improved property, a stop notice reaches the construction funds still flowing to the project, obligating the owner — or, in its most potent bonded form, the construction lender — to withhold sufficient funds from the general contractor to cover the claimant's unpaid amount. It is available in a minority of states, with California's regime the most developed, and on public projects it often serves alongside payment bond claims where liens are unavailable.

The remedy's power is its position in the cash flow. A lien is leverage that matures slowly — recording, then foreclosure litigation measured in years. A valid stop notice interrupts the next draw: money that would have paid the GC or the delinquent sub is frozen at the source, which concentrates minds immediately. Against a construction lender, a bonded stop notice (accompanied by a surety bond, typically 125% of the claim) creates personal liability for the lender if it disburses anyway — one of the few tools that reaches project financing directly. Deadlines and mechanics are strict and parallel to lien law: preliminary notice is generally a prerequisite, and service windows track the same last-furnishing timeline.

For credit teams operating in stop-notice states, the tactical guidance is to treat it as a companion to the lien, not an alternative — file both when exposure justifies it, because they attach to different assets (funds versus land) and pressure different parties. Availability, bonding requirements, and deadlines vary sharply by state, and several states have no stop-notice remedy at all; confirm the current rules in your project's state with counsel.
