What is a California stop payment notice?
Answer: A California stop payment notice is a signed and verified statutory notice used by an eligible unpaid construction claimant to reach specified project funds before those funds are disbursed. On a private project, a notice to the owner may be given to the owner or the owner’s architect, if any, and a separate notice may be given to the construction lender. On a public project, it is given to the public entity responsible for the contract funds.
California previously called this remedy a stop notice. The Legislature provides that older references to a stop notice mean a stop payment notice. On private works, a stop payment notice may be bonded or unbonded. The notice does not automatically stop construction, transfer money to the claimant, or guarantee recovery.
Effectiveness depends on the claimant’s eligibility, any required preliminary notice, the accuracy of the claim, the correct recipient and delivery method, the applicable deadline, available project funds, bond status, and timely enforcement.
What does the notice do?
A valid notice may require an owner or public entity to preserve enough undisbursed construction funds to address the stated claim, subject to the rules for that project. A private construction lender’s duty depends on whether the notice is bonded and whether other statutory conditions or exceptions apply. The remedy focuses on project funds, not title to the property.
For a claimant, this may preserve a source of recovery while a payment dispute is evaluated or litigated. For an owner, developer, lender, or direct contractor, receipt of a notice calls for prompt review. Paying funds without addressing an effective notice can create additional exposure, while withholding too much or responding to a defective claim can disrupt cash flow and project administration.
The notice amount may include only the amount due for work provided through the notice date.
Stop payment notices on private works
California Civil Code section 8520 permits a person with mechanics lien rights, other than the direct contractor, to give a stop payment notice to the owner. The notice may be delivered to the owner or the owner’s architect, if any. The owner generally must withhold a sufficient amount from funds due or to become due to the direct contractor, subject to statutory exceptions.
If the owner previously recorded a qualifying payment bond, the owner may decline to withhold. An owner that does so must notify the claimant within 30 days after receiving the stop payment notice and provide a copy of the bond. See Civil Code section 8522.
Under section 8530, a person with lien rights may also give a notice to the construction lender. A lender notice is effective only when delivered to the manager or another responsible person at the office or branch that administers or holds the construction funds. The lender’s response can depend on whether the notice is bonded, whether a qualifying payment bond was recorded, and the claimant’s place in the contract chain.
A private stop payment notice must be given before expiration of the claimant’s time to record a mechanics lien. Because that lien period depends on claimant type, completion, and whether the owner recorded a notice of completion or cessation, there is no single safe private-project deadline for every business.
Stop payment notices on public works
Public works use a separate statutory chapter. A public stop payment notice reaches public contract funds rather than placing a mechanics lien on public property. A direct contractor may not give a public-work stop payment notice under Civil Code section 9100. The notice must go to the recipient specified in Civil Code section 9354, which can include the director of the state department that awarded the contract, a public disbursing officer, or the governing body that awarded the work.
After receiving an effective notice, the public entity generally must withhold enough funds due or to become due to the direct contractor to cover the claim and the entity’s reasonable anticipated litigation costs. If several notices exceed the available funds, claimants generally share the fund proportionally rather than according to which notice arrived first.
Under section 9356, a public notice must be given within 30 days after recordation of a notice of completion, acceptance, or cessation. If none is recorded, the deadline is generally 90 days after completion or cessation. A public entity need not send the statutory reminder of the enforcement deadline unless the claimant pays the entity $10 when giving the notice; the fee is not a condition to the notice’s validity. See Civil Code section 9362.
Preliminary notice and enforcement deadlines
A preliminary notice may be a necessary prerequisite. On private works, the claimant must have given preliminary notice to the extent required before relying on a stop payment notice. Public works provide exceptions for laborers and claimants with a direct contractual relationship with the direct contractor. Other public claimants generally give preliminary notice to both the public entity and direct contractor.
A late public preliminary notice ordinarily preserves rights only for work provided within the 20 days before the preliminary notice and work provided afterward. The preliminary notice is not itself a demand to withhold money.
Giving a stop payment notice is also not the end of the process. For private and public works, an enforcement action may generally begin after 10 days from the date the notice was given. It generally must begin no later than 90 days after expiration of the period in which the stop payment notice could have been given. If the enforcement deadline is missed, the notice ceases to be effective and the withheld funds must be released.
On a private work, the claimant must notify every person to whom the stop payment notice was given within five days after commencing the enforcement action. On a public work, the action must be brought against both the public entity and the direct contractor, and the claimant must notify the public entity within five days after commencement. See Civil Code sections 8550 through 8560 and sections 9500 through 9510.
Bonded versus unbonded private notices
An unbonded stop payment notice is not accompanied by the claimant’s bond. It may still affect private project funds, but a construction lender may elect not to withhold in circumstances allowed by Civil Code section 8536.
A claimant may give a private construction lender a stop payment notice accompanied by a bond equal to 125 percent of the claim. If the lender objects to the sufficiency of the sureties within 20 days, the claimant may substitute a bond executed by an admitted surety insurer within 10 days after notice of the objection. If no substitute is provided, the lender may disregard the bonded notice and release funds withheld in response to it. A bonded notice removes the lender’s option not to withhold solely because the notice is unbonded, but other statutory exceptions may still apply.
This claimant bond is different from a release bond. On a private project, an owner, direct contractor, or subcontractor may secure release of withheld funds with a qualifying 125 percent release bond. On a public project, the public entity may permit the direct contractor to furnish a similar release bond.
What a stop payment notice is not
| Document or remedy |
How it differs |
| Preliminary notice |
Preserves specified remedies and alerts project participants. It generally does not require funds to be withheld. |
| Mechanics lien |
Is recorded against qualifying private real property. A stop payment notice reaches construction funds instead. |
| Payment bond claim |
Seeks recovery from a surety. A claimant may have both remedies, but each has separate requirements. |
| Stop work notice |
A separate private-work nonpayment remedy through which a qualifying direct contractor notifies the owner that the contractor will stop work. A stop payment notice does not automatically halt jobsite activity. See Civil Code section 8830. |
| Demand letter |
Requests payment or asserts contract rights but does not create the statutory withholding duty of an effective notice. |
Business scenario: unpaid subcontractor and active loan funds
A subcontractor completes approved work on a private development, submits a payment application, and remains unpaid while construction loan proceeds are still available. The subcontractor previously gave any required preliminary notice.
The subcontractor may need to evaluate a notice to the owner, lender, or both, along with whether a lender notice should be bonded. At the same time, the owner, developer, and direct contractor should verify eligibility, preliminary notice, the amount due, the recipient, remaining funds, and whether a release bond or negotiated resolution is appropriate.
Payment applications, disputed change orders, backcharges, retention, waivers, and prior payments can all affect the amount actually due. A notice strategy should therefore be coordinated with the contract claim, lien rights, payment bond rights, and any pending lawsuit or arbitration.
