Public construction projects in Arizona rely on a network of contractors, subcontractors, and suppliers working under strict regulations. The Arizona Little Miller Act plays a key role in ensuring that those providing labor and materials get paid, requiring general contractors on public projects to secure payment bonds. But while this law provides essential protections, it also gives rise to disputes—often leading to litigation, financial hardship, and project delays.
For contractors, subcontractors, and legal professionals, understanding these disputes is crucial. What causes them? How can claims be enforced effectively? What legal defenses do contractors use to fight claims? And when is the right time to consider alternative dispute resolution? This article breaks down the most common legal challenges tied to the Little Miller Act and reviews common strategies for resolving them.

Common Disputes Under Arizona’s Little Miller Act
Payment Disputes
Getting paid on a public construction project should be straightforward, but reality often proves otherwise. Subcontractors and suppliers frequently run into payment delays or outright denials, forcing them into a legal battle just to collect what they’re owed. While Arizona’s Little Miller Act provides a safety net through payment bonds, enforcing those rights isn’t always simple.
Why Payments Get Delayed or Denied
The most common reason a subcontractor doesn’t get paid? The general contractor is struggling financially. Even when work is completed as agreed, a contractor dealing with cash flow issues might delay payments—sometimes indefinitely.
Other disputes arise when contractors challenge the quality of work or materials. If a general contractor claims the work wasn’t up to spec or the wrong materials were used, they may refuse to pay until the issue is resolved. And then there’s the paperwork problem: A subcontractor may file a bond claim, only to have it denied due to missing documentation or procedural missteps. Bonding companies (sureties) have little patience for errors, and even a minor mistake in the claim process can be enough for them to reject payment.
Common Bond Claim Disputes Between Contractors and Subcontractors
Even when a subcontractor files a legitimate payment bond claim, the general contractor or surety often pushes back. Key points of dispute often involve:
- Scope of Work – The contractor may argue that the work performed wasn’t covered by the bonded contract, making it ineligible for payment.
- Proper Notice – The subcontractor must notify both the contractor and the surety before filing a claim—missing this step can give the surety grounds to deny payment.
- Statutory Deadlines – The law sets strict time limits for filing claims, and failing to meet them can be a fatal mistake.
How Compliance Mistakes Can Invalidate a Claim
The Arizona Little Miller Act comes with clear procedural requirements, and missing just one step can be enough to sink an otherwise valid claim. Some of the most common mistakes include:
- Blowing the Deadline – There’s a hard deadline for filing bond claims, and late filings are almost always rejected.
- Failing to Give Proper Notice – Subcontractors must formally notify the general contractor and surety within the legally required timeframe—no notice, no claim.
- Incomplete or Inaccurate Documentation – Payment claims require clear records—contracts, invoices, proof of work performed. A weak paper trail can be just as damaging as missing a deadline.
Subcontractor Tier Issues – Who Has the Right to File a Claim?
Not every subcontractor or supplier on a public project automatically qualifies for payment bond protection. Lower-tier subcontractors—those who contract with another subcontractor instead of directly with the general contractor—may face challenges in asserting their claims.
- Third-Tier and Lower Subcontractors – The further down the chain a subcontractor is, the harder it can be to enforce bond claims, as some sureties argue they lack standing under the Act.
- Supply Chain Conflicts – Suppliers providing materials to other suppliers (rather than directly to the contractor or a first-tier subcontractor) may also find their claims challenged.
General contractors and sureties frequently use subcontractor tier arguments to try and block bond claims, making it essential for lower-tier subcontractors and suppliers to carefully track contractual relationships.
Disputes Over Change Orders and Unapproved Work
Change orders and extra work not expressly approved in writing can create serious legal conflicts when it comes to payment under the Little Miller Act.
- Unapproved Work – If a subcontractor performs additional work that was not explicitly authorized by the general contractor, the surety may refuse to cover it under the bond.
- Verbal Agreements – Even if a contractor verbally approved a change, a lack of written documentation can give the surety a reason to dispute payment.
- Scope Creep – Contractors may argue that certain work was outside the original contract’s scope, leading to partial or full denial of a bond claim.
To avoid disputes, subcontractors should always insist on written change orders and maintain detailed records of project changes before performing additional work.
Retainage and Final Payment Holdbacks
Another major issue is retainage—the percentage of a subcontractor’s payment that is withheld until project completion. Retainage disputes arise when:
- The general contractor refuses to release retainage due to alleged defects, incomplete punch-list items, or disputes over final project quality.
- A surety argues that retainage is not covered under the payment bond, leaving subcontractors without a legal pathway to recover those funds.
- Delayed project closeouts result in extended waiting periods for final payments, even when the subcontractor’s work has long been completed.
While the Little Miller Act protects subcontractors’ rights to payment, final retainage disputes often turn into legal battles, particularly when contractors and sureties claim defects or delays justify withholding funds.
Surety Insolvency or Bond Denial Due to Bad Faith
Sureties are responsible for ensuring subcontractors get paid—but what happens when the surety itself refuses to honor a legitimate claim or goes out of business?
- Bad Faith Denials – Some sureties delay or deny valid bond claims without proper justification, forcing subcontractors to take legal action.
- Surety Insolvency – If a surety becomes financially unstable, subcontractors may be left scrambling to recover payment, sometimes needing to seek remedies against the general contractor directly.
Successfully navigating these disputes requires more than just knowing the law—it takes precision, strategy, and a strong understanding of the claim process. These common compliance pitfalls in construction projects reinforce the importance of working with an experienced construction lawyer to ensure all procedures are followed correctly.
How to Successfully Enforce a Claim Under Arizona’s Little Miller Act
Filing a payment bond claim under Arizona’s Little Miller Act isn’t just a matter of filling out paperwork—it’s about timing, precision, and persistence. A simple procedural mistake, such as missing a deadline or submitting incomplete paperwork, can jeopardize an otherwise valid claim. To maximize the chances of getting paid, subcontractors and suppliers need to follow three key steps: meet all statutory deadlines, compile airtight documentation, and follow the correct claim process.
1. Strict Deadlines: The Clock Starts Ticking Sooner Than You Think
Arizona law imposes strict time limits on Little Miller Act claims, and missing them means losing the right to recover payment—no exceptions. Under A.R.S. § 34-222, claimants must adhere to these critical deadlines:
- Preliminary Notice (Within 90 Days) – A subcontractor or supplier must send written notice to the general contractor and surety within 90 days of providing the last labor or materials on the project. This notice acts as a formal warning that a payment bond claim may be pursued.
- Filing the Claim (Within One Year) – If payment is still not received, the claimant must file a lawsuit against the bond within one year from the last date of work or material supply. Courts enforce this deadline strictly—miss it, and the claim is dead in the water.
These deadlines don’t leave much room for error. Subcontractors should track their last day of work carefully and send preliminary notices well before the 90-day cutoff to avoid disputes over timing.
2. Documentation: Building an Ironclad Claim File
A bond claim is only as strong as the evidence backing it up. Without solid documentation, sureties and general contractors will have an easier time challenging or denying payment requests. Every claimant should maintain a comprehensive claim file, including:
- Executed Contracts & Subcontracts – A signed contract confirms the scope of work and payment obligations. Without it, a surety may argue that the claim is invalid.
- Invoices & Payment Records – Documenting every payment request, including due dates and any partial payments, helps prove exactly what is owed.
- Email & Written Correspondence – Keeping records of all payment-related discussions (emails, letters, text messages) can demonstrate ongoing attempts to resolve non-payment.
- Proof of Preliminary Notice – Sending notice is required by law, but claimants should also keep proof of delivery (certified mail receipts, email confirmations) in case the contractor or surety disputes receiving it.
Pro Tip: Sureties often reject claims citing “insufficient proof”—meaning more documentation is always better than less. Keeping meticulous records can make the difference between getting paid and fighting an uphill legal battle.
3. Following the Correct Claim Procedure: A Step-by-Step Approach
Filing a Little Miller Act claim isn’t just about meeting deadlines—it’s about taking the right steps at the right time. Here’s how subcontractors should approach the process:
- Send a Formal Payment Demand to the General Contractor
- Before escalating to a bond claim, subcontractors should first send a written demand letter to the general contractor. This letter should outline the unpaid amount, reference the contract terms, and request immediate payment.
- Some disputes can be resolved at this stage, avoiding the need for legal action.
- File a Payment Bond Claim with the Surety
- If the general contractor fails to pay, the next step is submitting a formal claim to the surety that issued the payment bond.
- The claim should include all supporting documentation (contracts, invoices, notices, and proof of correspondence).
- Pursue Legal Action If the Surety Denies Payment
- If the surety refuses to pay or delays resolution, the claimant must file a lawsuit before the one-year deadline expires.
- A lawsuit can be filed against the surety itself, compelling them to honor the bond and make payment.
Skipping steps or delaying action can give contractors and sureties more leverage to deny a claim, so staying proactive is critical.
Why a Proactive Legal Strategy Matters
Successfully enforcing a Little Miller Act claim requires strict compliance with the law and careful attention to detail. Contractors and sureties are quick to challenge claims on procedural grounds, making timeliness and documentation essential.
For subcontractors and suppliers navigating this complex process, working with an experienced construction lawyer can help prevent mistakes, strengthen claims, and secure payment faster.
Challenges to Payment Claims Under Arizona’s Little Miller Act
Contractors and sureties frequently challenge payment bond claims, and disputes can become complex quickly. While the Little Miller Act is designed to ensure fair payment, claimants may encounter common defenses raised by general contractors and surety companies.
Important Note: The following are general descriptions of common disputes and defenses in Arizona Little Miller Act claims. This information is not legal advice and DOES NOT replace consulting with an experienced construction lawyer about your specific situation.
Common Defenses Contractors and Sureties Use to Challenge Claims
Missed Notice Deadlines
Strict deadlines apply to Little Miller Act claims, and if a subcontractor fails to provide timely notice to the general contractor or surety, the claim may be challenged. Some parties rely on procedural defenses, arguing that even a small delay in notice should invalidate the claim.
Work Allegedly Outside the Bonded Contract
Contractors and sureties sometimes dispute whether the work or materials in question fall under the bonded contract. They may argue that:
- The subcontractor performed extra work that was not pre-approved in writing.
- The claim involves materials or labor not included in the original scope of work.
Because Little Miller Act claims typically apply only to covered work, scope-related disputes are common.
Project Scope or Completion Disputes
Sureties may also contest whether the subcontractor completed the work according to the contract’s requirements. Some challenges in this area include:
- Disputes over whether the work was finished as required.
- Claims that the materials or labor didn’t meet contractual standards.
- Requests for additional proof before considering payment.
These disputes often involve project records, documentation of completed work, and independent assessments.
Options for Resolving Little Miller Act Disputes
Although some payment disputes end up in litigation, many can be resolved through Alternative Dispute Resolution (ADR). Many public construction contracts include ADR provisions, and subcontractors may have options outside of court.
Mediation for Construction Disputes
In mediation, a neutral third party helps both sides work toward a mutually agreeable resolution.
- It’s often required before filing a lawsuit, depending on contract terms.
- Mediation is faster and less expensive than court proceedings.
- Agreements reached in mediation are typically voluntary and non-binding.
Arbitration for Construction Issues
Arbitration is a formal dispute resolution process where an impartial arbitrator reviews the evidence and issues a final, legally enforceable decision.
- Arbitration follows a more structured process than mediation but is generally quicker and more affordable than taking a case to court.
- Many public construction contracts include mandatory arbitration clauses.
- Arbitration decisions are legally enforceable, meaning parties must comply.
Construction Litigation
When alternative dispute resolution isn’t successful or isn’t available, taking the dispute to court might be the only option to completely resolve the matter.
- If the claim is upheld, the court can require full payment.
- Litigation can be a lengthy and costly process, which is why many parties explore ADR first whenever possible.
