Payment disputes range from small invoicing disagreements to full non-payment that threatens cash flow and project timelines. In a 2022 industry survey, only 12% of construction businesses said they always got paid on time, and 18% reported missing payroll because of slow payment, according to Levelset's Construction Cash Flow & Payment Report.
This article covers why disputes happen, the step-by-step resolution process, the legal remedies available under California law, and when to call in a construction litigation attorney.
Key Takeaways
- Most disputes stem from unclear contract terms, unapproved change orders, or quality disagreements
- Document everything first, negotiate directly second, escalate only when necessary
- California law gives you mechanic's liens, stop payment notices, and bond claims to secure unpaid amounts
- Statutory deadlines are strict and unforgiving, so early legal consultation protects your rights
How to Resolve a Contractor Payment Dispute: A Step-by-Step Process
Step 1: Review the Contract and Document the Dispute
Pull the contract before you do anything else. Look specifically at:
- Payment terms: schedule, invoicing requirements, retention percentage
- Scope of work: what was actually agreed to versus what was performed
- Change order provisions: how additional work gets approved and priced
- Retention clauses: when retention releases and under what conditions
Gather every piece of supporting evidence: invoices, signed change orders, daily logs, photos, and email or text correspondence. This paper trail becomes your leverage in negotiation and your evidence if the dispute escalates.
Many California construction contracts include "pay-if-paid" or "pay-when-paid" language, but California treats these clauses very differently. A true pay-if-paid clause, which shifts the owner's non-payment risk entirely onto the subcontractor, violates public policy and is unenforceable under Wm. R. Clarke Corp. v. Safeco Insurance Co. of America (1997) 15 Cal.4th 882.
A pay-when-paid clause works differently: it may only delay payment for a reasonable period, not withhold it indefinitely or defeat statutory bond claims. Given how easily these clauses get misread, have an attorney review the exact wording before you assume you have no recourse.
Step 2: Communicate and Attempt Direct Negotiation
Send a formal written demand. State the amount owed, the contractual basis for that amount, and a firm deadline for response.
Keep the tone professional and fact-based, not accusatory. Loop in the relevant stakeholders, whether that's the owner, the general contractor, or the subcontractor, so the conversation happens transparently rather than through side channels that breed suspicion.
A clear, well-documented demand letter resolves a surprising number of disputes before they ever need statutory remedies. It also creates a paper trail that strengthens your position if negotiation fails.
Step 3: Preserve Statutory Rights With Timely Notices
Don't wait to see how negotiation goes before protecting your legal rights. California requires a preliminary notice, sometimes called a Notice to Owner, within 20 days after you first furnish labor or materials on most private works projects, per California Civil Code Section 8204.
Miss that window and you don't lose everything, but late notice only protects the work furnished in the 20 days before you served it and afterward. Anything furnished earlier falls outside your lien and stop notice protection.
This step runs on a separate clock from your negotiation efforts. Serve the notice regardless of how settlement talks are going.
Step 4: Escalate to Formal Resolution if Needed
If direct negotiation stalls, check your contract's dispute resolution clause. Many California construction contracts require mediation or arbitration before either party can file suit.
At this stage, three things typically happen at once:
- Filing a mechanic's lien, stop notice, or bond claim to secure leverage while other resolution methods proceed
- Initiating the contractually required ADR process (mediation or arbitration)
- Preparing for litigation as a last resort if statutory remedies and ADR both fail
Litigation makes sense for large, complex disputes where other remedies haven't worked. It's rarely the first move, but it's sometimes the only one that produces payment.
Legal Remedies & Protections for Unpaid Contractors and Suppliers
Beyond direct negotiation, California law gives unpaid contractors, subcontractors, and suppliers real statutory leverage. Each remedy reaches a different pool of money or property, so understanding which applies to your situation matters.
Mechanic's Liens
A mechanic's lien attaches directly to the real property that received your work. Eligible claimants include direct contractors, subcontractors, material suppliers, equipment lessors, laborers, and design professionals.
The lien amount generally equals the lesser of the reasonable value of the work or the contract price. Timing is unforgiving:
| Claimant Type | Deadline After Completion | Deadline After Notice of Completion/Cessation |
|---|---|---|
| Direct contractors | 90 days | 60 days |
| Subcontractors & suppliers | 90 days | 30 days |
Once recorded, you must file a foreclosure lawsuit within 90 days, per California Civil Code Section 8412, or the lien expires and becomes unenforceable.
Stop Notice Claims
A stop notice reaches construction funds still held by the owner or lender, before they're disbursed. This matters when the property itself doesn't have enough equity to make a lien meaningful, or when you want to freeze money before it moves further down the payment chain.
Claimants can also post a bond equal to 125% of the claim amount, which generally makes lender withholding mandatory rather than optional.
Bond Claims
On public works projects, where liens aren't available because you can't lien government property, unpaid subcontractors and suppliers can claim against the general contractor's payment bond instead. California's "Little Miller Act" requires a payment bond on public contracts over $25,000, generally covering 100% of the contract amount.
Notice and filing requirements here are just as strict as private-work liens, with separate deadlines depending on whether a Notice of Completion was recorded.
Prompt Payment Statutes
California's prompt payment laws impose real financial consequences for late payment. Several statutes allow 2% interest per month on wrongfully withheld amounts, plus attorney's fees for the prevailing party.
Timing every one of these remedies requires precision, since missing a single deadline can forfeit the entire claim. Carno Law Group represents contractors, subcontractors, and suppliers across Orange, Los Angeles, Riverside, San Bernardino, and San Diego Counties, handling everything from preliminary notice service through lien foreclosure and bond enforcement.
Choosing the Right Resolution Method: Negotiation, Mediation, Arbitration, or Litigation
The right path depends on your contract's dispute resolution clause, the value of the business relationship, and the size of the amount in dispute.
| Method | Best For | Speed & Cost | Key Limitation |
|---|---|---|---|
| Negotiation | Lower-dollar disputes, relationships worth keeping | Fastest, cheapest | Requires cooperation from both sides |
| Mediation | Parties wanting control over the outcome | Moderate | Non-binding; can fail if one side won't engage |
| Arbitration | Contract-mandated or faster private resolution | Faster than court, still costs money | Limited appeal rights |
| Litigation | Large claims, statutory enforcement, uncooperative parties | Slowest, most expensive | No confidentiality; case becomes public record |
Negotiation works best when the dollar amount is manageable and you want to preserve the working relationship. Even informal agreements should be confirmed in writing to prevent later disputes over what was promised.
Mediation brings in a neutral third party to help both sides reach a mutually acceptable resolution. Coming prepared with clear documentation and a willingness to compromise improves your odds of reaching an agreement instead of restarting the process later.
Arbitration suits disputes where the contract mandates it, or where both parties want a faster, private, binding alternative to court. Check your dispute resolution clause first, since many construction contracts already require arbitration before litigation becomes an option.
Litigation becomes necessary for large claims, statutory lien or bond enforcement, or when the other side simply refuses to cooperate. This route preserves your right to a jury trial and full discovery, tools unavailable in arbitration or mediation.
Whichever route fits your dispute, Carno Law Group can help. The firm represents clients in both California state and federal courts, and also provides mediation and arbitration services directly, giving contractors a cost-effective path to resolution without always defaulting to a courtroom.
Common Causes and Mistakes That Escalate Payment Disputes
Most payment disputes trace back to a handful of preventable problems:
- Vague or incomplete contracts: missing payment schedules, unclear scope definitions, or ambiguous retention terms leave too much room for interpretation
- Unapproved change orders: work performed before written authorization creates disagreement over what's actually owed
- Missed statutory deadlines: failing to serve California's required preliminary notice or record a mechanic's lien on time can permanently forfeit remedies that would otherwise apply
- Poor documentation: not tracking completed work, correspondence, and change orders weakens your negotiating position when the dispute surfaces
Nearly half of contractors in one industry survey reported giving up lien rights out of fear of damaging a customer relationship. That's an understandable instinct, but it's also how valid claims quietly disappear.
Conclusion
Most contractor payment disputes get resolved through clear documentation, prompt communication, and a solid grasp of your statutory rights. The remedies exist. The problem is usually timing, not entitlement.
Missing a notice or lien deadline doesn't just weaken your position — it can permanently forfeit your right to payment under California law. There's no grace period for "I didn't know."

Frequently Asked Questions
What should I do if a contractor is not paying me?
Document the completed work, send a written demand outlining the amount owed and your deadline for response, and review your contract's dispute resolution clause. If that doesn't resolve it, consider a mechanic's lien, stop notice, or a consultation with a construction attorney.
What should I do if I get ripped off by a contractor?
Gather evidence of payments made and work performed, then review your contract terms closely. Attempt direct resolution first, but consult a construction litigation attorney promptly if you suspect fraud or a clear breach of contract.
How long do I have to file a mechanic's lien in California?
Deadlines vary by claimant type and whether a Notice of Completion was recorded, generally ranging from 30 to 90 days under California Civil Code §8412 and related sections. Because these windows are strictly enforced, verify your exact deadline and consult an attorney right away.
Can a contractor withhold payment for subpar work?
Yes, but the withholding party must document the specific reasons and follow the procedures outlined in the contract. Withholding without justification or proper process can expose them to a breach of contract claim.
What's the difference between a stop notice and a mechanic's lien?
A mechanic's lien attaches to the real property that received the work. A stop notice reaches construction funds still held by a lender or owner before those funds are disbursed.
Do I need a lawyer to resolve a construction payment dispute?
Small, straightforward disputes can sometimes be handled directly between the parties. Once statutory deadlines, liens, bonds, or significant dollar amounts are involved, consulting a construction attorney, such as those at Carno Law Group, protects your rights and preserves your options. Except in small claims matters, corporations and LLCs must appear through a licensed attorney in limited and unlimited civil court proceedings.
