Dealing with Underinsured Motorist Coverage Disputes in Arizona

Understanding Underinsured Motorist Coverage in Arizona

Underinsured Motorist (UIM) coverage is a critical component of an auto insurance policy in Arizona, designed to protect you when an at-fault driver’s liability limits are insufficient to cover your damages. Unlike uninsured motorist (UM) coverage, which applies when a driver has no insurance, UIM steps in when the at-fault party’s insurance exists but is inadequate. Arizona law requires insurers to offer both UM and UIM coverage, but policyholders have the right to reject it in writing. Disputes frequently arise when insurance companies undervalue or deny UIM claims, leaving injured parties to navigate a complex legal and insurance landscape to secure the compensation they are owed.

The Legal Framework: Arizona’s UIM Laws and Requirements

Arizona’s UIM statute, A.R.S. § 20-259.01, mandates that every automobile liability insurance policy issued in the state must include UM and UIM coverage equal to the policy’s bodily injury liability limits unless specifically rejected by the insured in writing. This “rejection must be in writing” requirement is strictly enforced by courts. The purpose of UIM coverage is to place the insured in the same financial position they would have been in had the at-fault driver carried sufficient liability insurance.

A key legal principle governing UIM claims is the “add-on” versus “reduction” distinction. Arizona is an “add-on” state. This means your UIM coverage is added on top of the at-fault driver’s liability payout. For example, if you have $100,000 in UIM coverage and the at-fault driver has a $50,000 policy limit, your total potential recovery could be $150,000. This is different from “reduction” states, where the UIM coverage would be reduced by the amount received from the at-fault driver.

Another critical concept is “stacking.” Arizona permits both intra-policy and inter-policy stacking of UIM coverage unless explicitly waived by the insured. Intra-policy stacking allows you to combine the UIM limits for multiple vehicles on a single policy. Inter-policy stacking allows you to combine UIM coverage from multiple policies, such as your auto policy and a household member’s policy. Waivers of stacking must also be made knowingly and in writing.

Common Reasons for UIM Claim Disputes and Denials

Insurance companies are for-profit entities, and their goal is to minimize payouts. This inherent conflict of interest leads to several common tactics used to dispute UIM claims.

• Disputing the Severity of Injuries: The most frequent area of contention is the nature and extent of your injuries. Your insurer may argue that your medical treatment was excessive, not medically necessary, or unrelated to the crash. They might downplay soft-tissue injuries or rely on their own hired “independent” medical examiners (IMEs) to contradict your treating physicians.
• Challenging Causation: The insurer may concede you were injured but argue that a pre-existing condition (e.g., a prior back injury or degenerative disc disease) is the true source of your pain, not the accident. Arizona law still entitles you to compensation if the accident aggravated or accelerated a pre-existing condition, but insurers often fight this vigorously.
• Low Settlement Offers and Bad Faith Tactics: An insurer may make a quick, low-ball settlement offer hoping you will accept it out of financial desperation. They might also delay the claims process unnecessarily, fail to conduct a proper investigation, or misinterpret policy language to justify a denial. These actions can form the basis of a bad faith insurance lawsuit.
• Policy Interpretation Disputes: Disagreements can arise over the specific language in your policy. This includes issues like whether you were “using” a covered vehicle at the time of the incident, who qualifies as an “insured” under the policy, or the validity of a stacking waiver.
• Offset and Subrogation Issues: Your insurer has a right of subrogation, meaning they can seek reimbursement from the at-fault driver for the UIM benefits they paid you. Disputes can occur over the amount of this subrogation lien, particularly if your total recovery from the at-fault driver and your UIM insurer is not enough to cover all your damages.

The UIM Claims Process: A Step-by-Step Guide

Navigating a UIM claim requires a meticulous and strategic approach.

1. Exhaust the At-Fault Driver’s Policy: Before you can make a UIM claim, you must first obtain a settlement from the at-fault driver’s insurance company for their full policy limits. You must provide your own insurer with written notice of a potential UIM claim and often need their consent before accepting any settlement from the at-fault driver to protect their subrogation rights.
2. Formal UIM Claim Submission: Once the underlying liability policy is exhausted, you must formally submit a UIM claim to your insurer. This submission should be comprehensive and include all evidence of your damages: medical records and bills, documentation of lost wages, a physician’s narrative report linking the injuries to the accident, proof of the other driver’s policy limits, and a detailed demand letter outlining the full value of your claim.
3. The Insurance Company’s Investigation: Your insurer will assign an adjuster to investigate your claim. This will likely involve reviewing your submitted evidence, recording a statement from you, and potentially requesting an Independent Medical Examination (IME). It is crucial to be prepared for this process and to understand that the IME doctor is selected and paid by the insurance company.
4. Negotiation and Settlement: The adjuster will evaluate your claim and make a settlement offer. This is almost always lower than your demand. Skilled negotiation, backed by strong evidence, is essential to reach a fair settlement. You must be prepared to justify every dollar of your demand with objective evidence.
5. Invoking the Appraisal Clause: Many Arizona auto policies include an appraisal clause for resolving disputes over the value of a claim. If you and your insurer cannot agree on the value of your damages, either party can invoke this clause. Each side hires an appraiser, and if they cannot agree, an umpire is selected. The umpire’s decision on the value is typically binding. This can be a faster and less expensive alternative to litigation but is generally only for disputes over the dollar amount of damages, not issues of liability or coverage.
6. Filing a Lawsuit: If negotiations and appraisal fail, filing a lawsuit against your own insurance company is the final recourse. The lawsuit can allege breach of contract for failing to pay the UIM benefits owed. If you can demonstrate that the insurer acted unreasonably in its handling of your claim, you may also have a separate cause of action for insurance bad faith, which can allow for recovery of damages beyond the policy limits, including emotional distress and punitive damages.

Maximizing Your UIM Claim: Essential Evidence and Strategies

Your ability to prevail in a UIM dispute hinges on the strength of your evidence.

• Comprehensive Medical Documentation: Seek immediate and consistent medical care. Follow all treatment recommendations. Your medical records are the foundation of your claim. Obtain detailed reports from your doctors that explicitly state the accident caused your injuries and detail your prognosis and any permanent impairments.
• Economic Damages Calculation: Meticulously document all accident-related expenses. This includes all medical bills, pharmacy costs, transportation to appointments, and proof of lost income from missed work. Future medical expenses and loss of earning capacity often require expert testimony from a medical doctor and an economist.
• Non-Economic Damages Justification: Pain and suffering, emotional distress, and loss of enjoyment of life are subjective but compensable. A personal journal detailing your daily struggles, testimonies from family and friends, and expert psychological evaluations can powerfully substantiate these intangible losses.
• Understanding Policy Details: Obtain a full copy of your insurance policy and carefully review its declarations page, definitions, and UIM provisions. Look for any waivers or endorsements that might affect your coverage, such as a stacking waiver or a “consent-to-settle” clause.

Why Legal Representation is Critical in UIM Disputes

Engaging an experienced Arizona personal injury attorney who specializes in insurance disputes is arguably the most important step you can take. The process is inherently adversarial. Your insurer has legal teams and adjusters whose job is to protect the company’s bottom line. An attorney levels the playing field.

A skilled lawyer understands the tactics insurers use and how to counter them. They handle all communications with the adjuster, preventing you from making statements that could be misconstrued. They know how to properly value a claim, assemble a compelling demand package, and negotiate aggressively. If a lawsuit becomes necessary, they can navigate the complex civil litigation rules and present a compelling case to a judge or jury. Most personal injury attorneys work on a contingency fee basis, meaning they only get paid if they recover money for you, making quality legal representation accessible.
