One Year, Not Two: The Deadline Arizona PI Firms Miss On Work Injury Referrals

Key Takeaways:

• A work injury can support both a workers’ compensation claim and a separate claim against an outside party.
• Arizona’s third-party statute creates a critical one-year action deadline that is different from the deadline many firms associate with ordinary injury cases.
• Missing that first-year deadline can cause the employee’s claim against the third party to be deemed assigned to the workers’ compensation carrier or self-insured employer.
• Fast intake, early investigation, and written communication with the carrier can help protect a viable referral.
• Evidence, lien issues, government notice rules, and the identity of every potential defendant should be assessed immediately.

Why Work Injury Referrals Need A Different Deadline Screen

Arizona personal injury firms routinely see clients hurt while working: delivery drivers struck in traffic, tradespeople injured on multi-employer jobsites, warehouse employees hurt by equipment, and workers who fall on someone else’s property. The referral may arrive with an accepted workers’ compensation claim already open, which can create a false sense that time is under control. It may not be.

When an outside person or business may have caused the injury, firms need to assess Arizona’s one-year deadline for third-party claims before treating the matter like a standard two-year auto, premises, or negligence case. The issue is not merely whether a lawsuit could eventually be filed. It is whether the injured worker preserves control of the third-party claim during the first year after it accrues.

That distinction matters in a state where work frequently happens on busy Phoenix and Tucson roads, sprawling construction sites, distribution centers, farms, mines, and customer properties. A worker may have a compensation claim against an employer’s carrier while also holding a negligence claim against a driver, subcontractor, property owner, maintenance vendor, manufacturer, or other party outside the worker’s employment.

Workers’ compensation and third-party liability are separate paths. Compensation benefits can address covered medical treatment and wage-related benefits without requiring the worker to prove employer fault. A civil claim against an outside party can involve damages not ordinarily available through workers’ compensation, but it requires its own timely action, proof, and case management.

Where Third-Party Claims Arise In Arizona

A third party is generally someone other than the injured worker’s employer or a person in the same employ. Intake teams should resist the urge to label a file “workers’ comp only” before identifying every person, business, vehicle, product, and location involved in the event.

Common Referral Fact Patterns

• A commercial driver, rideshare driver, or ordinary motorist hits an employee making deliveries or traveling between job locations.
• A subcontractor creates a dangerous condition that injures an employee of another company on the same project.
• A property owner or management company fails to address a hazard at a customer site, apartment complex, retail location, or loading area.
• A defective machine, tool, vehicle component, ladder, or safety device contributes to an injury.
• A vendor, repair company, or equipment renter performs work carelessly and creates a foreseeable risk.

The facts can be more complicated than they first appear. Contract relationships, employer identities, jobsite control, and the worker’s actual task at the time of injury may all affect the analysis. That is why a short conflict check and a complete liability screen should occur at intake, not months later after records finally arrive.

The One-Year Rule & Why Two Years Can Be Too Late

Arizona Revised Statutes section 23-1023 permits an employee entitled to compensation to pursue a remedy against a negligent third person not in the same employ. But if the employee or dependents do not institute an action within one year after the cause of action accrues, the claim is deemed assigned to the compensation carrier or self-insured employer. The current language of Arizona’s third-party liability statute should be part of every work injury referral review.

This is the deadline PI firms miss when they rely only on the general limitations period they would use for a conventional injury case. The worker may still have a potential path after assignment, including a reassignment by the carrier, but a firm should not assume reassignment will be available, prompt, or favorable. The best practice is to identify the one-year date immediately and act well before it.

Build A Deadline Sheet On Day One

• Record the accident date and the date the injury became apparent.
• Identify the potential third-party defendants and whether any are public entities.
• Calendar the one-year third-party action date with advance reminders.
• Check for shorter notice requirements, contractual issues, or specialized claims.
• Confirm the workers’ compensation carrier or self-insured employer and claim number.
• Document written notice of the worker’s intention to pursue the third-party matter.

Arizona law also requires the employee or dependents to give the carrier or self-insured employer written notice of an intention to bring a third-party action and timely, periodic notice of pleadings and rulings. The carrier may intervene to protect its interests. A referral process that overlooks these communication duties can create avoidable friction later.

A Practical First-Week Referral Protocol

Speed does not mean rushing to conclusions. It means preserving options while the facts are still available. Request the incident report, police report when applicable, employer report, photographs, video, witness information, insurance details, and relevant contracts or work orders. Send preservation requests when there is a legitimate reason to believe video, vehicles, equipment, or electronically stored information may be relevant.

Confirm that the worker has also taken the necessary compensation steps. The Industrial Commission of Arizona explains that an injured worker may file a written claim through its Worker’s Report of Injury process, and that the filing period is generally one year after injury or manifestation of a compensable work-related injury. That compensation deadline is important, but it does not replace the separate third-party analysis.

Evidence That Disappears Quickly

In Arizona heat, monsoon conditions, road construction, and constantly changing jobsites, an accident scene may look very different within days. Surveillance systems overwrite footage. Damaged equipment is repaired or discarded. A delivery vehicle is returned to service. Witnesses scatter to other projects. Early documentation often determines whether a theory of fault can be tested later.

Helpful materials may include scene photographs, vehicle data, safety meeting records, inspection logs, maintenance records, dispatch information, delivery records, training documents, witness statements, medical records, and wage documentation. Where a product is involved, preserve the item and its condition whenever possible. Do not permit destructive testing or disposal without understanding its potential evidentiary value.

Coordinating Workers’ Compensation & Civil Claims

Coordination is essential because the compensation carrier may have a lien on amounts recovered from the responsible third party for benefits it paid. The lien calculation, future benefits, litigation expenses, attorney fees, and settlement terms should be analyzed before a release is signed. A settlement for less than the compensation and medical benefits provided may require written carrier approval under the statute.

Firms should obtain an itemized benefits history, verify the correct lien holder, and communicate in writing about the third-party action. This is particularly important when a civil recovery may affect continuing compensation obligations or when settlement discussions begin before treatment is complete.

Common Errors That Cost Time & Leverage

• Assuming an open compensation claim protects the civil claim.
• Using only a two-year limitations calendar for a work-related referral.
• Failing to identify a potential third party until after the first anniversary of the injury.
• Waiting too long to seek video, inspect equipment, or locate witnesses.
• Neglecting written notice to the compensation carrier.
• Settling without confirming lien figures and approval requirements.
• Overlooking special rules that may apply when a government entity is involved.

Final Thoughts

For Arizona PI firms, the central lesson is simple: a work injury referral should trigger two clocks, not one. The workers’ compensation matter needs attention, but a possible third-party claim demands an immediate one-year deadline review. Early investigation, careful calendaring, carrier communication, and coordinated lien planning give injured workers the best chance to preserve every available path to recovery.
