3.3 Stop Payment Notices & Payment Bond Claims

Stop Payment Notices & Payment Bond Claims

While a mechanics lien encumbers real property title, a Stop Payment Notice (formerly referred to as a Stop Notice) targets the construction cash flow. It is a statutory demand served on a property owner, construction lender, or public entity to trap undisbursed construction funds in their hands (California Civil Code Sections 8500–8560 for private works and Civil Code Sections 9350–9566 for public works).

Stop payment notices are particularly critical when property encumbrances exceed property value on private builds, or on public works projects where liens against public land are strictly prohibited by law.

Private Works Stop Payment Notices

On private construction projects, sub-tier contractors, material suppliers, and equipment lessors can issue a Stop Payment Notice to trap undisbursed construction loan funds or owner funds.

Direct Contractor vs. Subcontractor Rights

• Subcontractors & Suppliers: May serve a Stop Payment Notice on both the property owner and the construction lender.
• Direct Contractors (Prime): Cannot serve a Stop Payment Notice on the owner (with whom they have direct contract privity), but CAN serve a Stop Payment Notice on the construction lender.

Unbonded vs. Bonded Stop Payment Notices to Lenders

When serving a Stop Payment Notice on a private construction lender, the distinction between an unbonded and bonded notice is critical:

Under Civil Code Section 8538, a Bonded Stop Payment Notice must be accompanied by a bond issued by an admitted surety insurer in a penal sum equal to 125% of the claim amount. This bond protects the lender and borrower against damages if the claimant loses the underlying dispute.

Public Works Stop Payment Notices

Under California law, public property cannot be liened. Unpaid subcontractors and suppliers on projects owned by cities, counties, school districts, state agencies, or Caltrans cannot file a mechanics lien. Their primary remedies are Public Works Stop Payment Notices and Payment Bond Claims (Civil Code Sections 9350–9510).

Public Entity Withholding Obligation (125% Withhold)

Upon receiving a timely, valid Stop Payment Notice from an eligible subcontractor or supplier (who served a 20-day Preliminary Notice under Civil Code Section 9300), the public entity MUST withhold 125% of the claimed amount (100% for the claim plus 25% to cover potential litigation costs and interest) from payments due to the prime contractor.

Public Works Stop Notice Filing Deadlines

A public works Stop Payment Notice must be served on the public entity within:

• 30 calendar days after recordation of a Notice of Completion, Notice of Acceptance, or Notice of Cessation.
• 90 calendar days after actual completion or continuous 60-day cessation of labor if no notice is recorded.

Public Works Payment Bonds & The Little Miller Act

To ensure sub-tier contractors and suppliers are protected on public projects, California enacted Civil Code Section 9550 (commonly known as California's Little Miller Act, mirroring the federal Miller Act).

Public Works Security Structure:
[Public Entity Contract > $25,000] 
       |
       +--> Requires 100% Payment Bond from Direct Contractor (CC 9550)
       +--> Allows Sub/Supplier Stop Payment Notice (125% Cash Trapped)

The Mandatory $25,000 Threshold

Under Civil Code Section 9550, every direct contractor awarded a public works contract exceeding $25,000 MUST file a statutory Payment Bond with the public entity before commencing work.

• Bond Amount: Must equal 100% of the total contract price.
• Issuer: Must be executed by an admitted surety insurer licensed in California.
• Beneficiaries: All sub-tier subcontractors, material suppliers, equipment lessors, and laborers.

Preliminary Notice & Bond Claim Prerequisites (Civil Code § 9560)

To assert a claim against a public works payment bond, a claimant must have served a 20-day Preliminary Notice under Civil Code Section 9300.

Exception: If a claimant failed to serve a timely Preliminary Notice, Civil Code Section 9560 allows them to enforce a payment bond claim if they give written notice to the direct contractor and surety within:

1. 15 calendar days after recordation of a Notice of Completion.
2. 75 calendar days after actual completion if no Notice of Completion was recorded.

Statute of Limitations for Payment Bond Lawsuits (Civil Code § 9558)

A lawsuit to enforce a claim against a public works payment bond MUST be filed in court within 6 months after the expiration of the period in which a Stop Payment Notice may be served under Civil Code Section 9356.
