Duty to Defend

Liability insurance ordinarily promises more than payment of a covered judgment. It also promises a legal defense. Arizona treats that defense obligation as separate from—and broader than—the ultimate duty to indemnify, while permitting actual coverage facts to matter in appropriate cases.

Current-law review: Sept. 13, 2026 Kepner Morris Quihuis Teufel Defense ≠ indemnity

The duty to defend is broader than the duty to pay a judgment

A liability insurer can be required to defend a lawsuit even though facts later establish that it ultimately owes no indemnity.

Defense

Protect the insured in the lawsuit

The insurer provides and funds the legal defense required by the liability policy when a claim potentially falls within the defense obligation.

VERSUS
Indemnity

Pay a covered liability

The insurer pays a settlement or judgment only to the extent the resulting liability actually falls within the policy's indemnity coverage.

Arizona rule: defense is separate from and broader than indemnity. Do not treat a carrier's assertion that it ultimately owes no coverage as automatically resolving whether it was required to defend the lawsuit while that issue was uncertain.

The complaint is the usual starting point

Kepner, Quihuis and Teufel state the basic rule: the defense obligation generally arises when the complaint alleges facts that, if true, would fall within the policy's coverage.

Read allegations—not labels

Identify the factual conduct and damages alleged rather than relying solely on the legal title attached to a cause of action.

Compare with the insuring agreement

Determine whether those alleged facts potentially satisfy the policy's insured, vehicle, occurrence and damages requirements.

A lawsuit need not ultimately succeed to trigger the defense. Arizona recognizes a defense obligation for claims that may later prove groundless, false or fraudulent if they fall within the policy's defense promise.

Arizona is not an absolute “four corners of the complaint” jurisdiction

Kepner permits facts outside the pleading to matter when those facts plainly establish that the claim falls outside coverage.

Complaint

Appears potentially covered

The allegations, viewed alone, appear to bring the liability claim within the policy.

Actual Coverage Facts

Plainly outside the policy

Reliable facts discovered outside the complaint may establish a coverage fact that the liability pleading does not address.

This is a coverage inquiry—not permission to prejudge the tort case. The outside fact should concern whether the policy covers the insured, vehicle, event or risk, rather than merely whether the claimant will prevail on liability.

Kepner example

The complaint appeared to allege a covered injury, but facts outside the pleading established that the power saw involved was being used in a business activity falling within a policy exclusion.

The Arizona Supreme Court held that the insurer was not absolutely obligated to defend merely because that exclusion-triggering fact was omitted from the complaint.

One covered claim can require defense of the entire lawsuit

Arizona does not ordinarily permit the liability insurer to carve a single action into covered and uncovered defense fragments once a claim triggers the defense obligation.

Count I

Potentially covered

The allegations potentially fall within liability coverage.

Count II

Potentially excluded

Another theory may ultimately fall outside indemnity coverage.

Defense Result

Defend the action

If any claim triggers coverage, Arizona generally requires defense against all claims in the suit.

Teufel: if any claims fall within policy coverage, the insurer must defend against all claims, including those potentially not covered and those that are groundless, false or fraudulent.

Defense and indemnity must remain separate throughout the case

Question Duty to defend Duty to indemnify
When analyzed? Usually at the beginning of the liability case. Often depends on facts ultimately established or settled.
Standard Potential coverage can trigger the duty. Actual covered liability is ordinarily required.
Scope Broader. Narrower and tied to the actual policy obligation.
Groundless claim May still have to be defended. No payment if no covered liability results.
Wrong refusal to defend Can create breach damages. Does not automatically manufacture indemnity coverage that was never purchased.
Quihuis: a wrongful failure to defend should not be used simply to create indemnity coverage for a risk the policy did not insure.

A reservation of rights permits defense while the coverage dispute remains open

When the insurer believes a claim should be defended but also believes a policy exclusion, definition or other coverage issue may ultimately eliminate indemnity, it can defend under a properly communicated reservation of rights.

Path 1 Defend without reservation

The carrier accepts the defense without preserving the identified coverage dispute.

Path 2 Defend under reservation

The insured receives a defense while the insurer preserves specified coverage defenses.

Path 3 Refuse to defend

The insurer concludes there is no defense obligation and accepts the legal risk that the decision may later prove wrong.

A reservation creates a real conflict of interests. The insured may be defended against the tort claim while simultaneously facing the possibility that the carrier will later refuse to indemnify the judgment.

Morris protects an insured being defended under reservation

In United Services Automobile Association v. Morris, the Arizona Supreme Court addressed whether insureds being defended under a reservation could settle without violating their cooperation obligations.

Arizona's answer: an insured defended under reservation may take appropriate steps to protect against the risk of noncoverage or personal liability without automatically breaching the cooperation clause.
Carrier reserves coverage rights. The insurer continues the defense but preserves its right to contest indemnity.
Insured faces personal risk. If coverage later fails, the insured may face the resulting liability personally.
Claimant and insured negotiate. The insured may seek a covenant protecting personal assets.
Settlement is documented. The insured can stipulate to liability or judgment under the applicable Arizona requirements.
Rights against insurer may be assigned. Applicable contract or bad-faith rights can become part of the arrangement.
Coverage remains litigable. The insurer generally retains legitimate policy coverage defenses.
A Morris agreement is not a blank check. Arizona imposes requirements concerning fairness, notice and the absence of fraud or collusion, and the settlement can be subject to a reasonableness inquiry where Arizona law permits.

Damron addresses the insured abandoned without a defense

Damron v. Sledge involved insurers that declined to defend the insured in an automobile liability action.

Arizona recognized that an insured facing personal liability after the carrier refuses to defend need not simply expose personal assets while waiting for the insurance dispute to be resolved.

Covenant not to execute

The claimant can agree not to pursue the insured's personal assets.

Assignment

The insured may assign applicable claims against the insurer to the claimant.

Damron's principle: an insured abandoned by the insurer may reasonably protect against the personal liability created by that abandonment.

Damron and Morris should not be treated as interchangeable labels

Issue Damron Morris
Carrier position Carrier has refused or failed to defend. Carrier is defending under a reservation of rights.
Insured's risk Insured lacks the promised carrier-funded defense and faces personal liability. Insured has a defense but remains exposed to a later noncoverage determination.
Cooperation clause Carrier's breach can substantially release the insured from ordinary cooperation restrictions. Reservation changes the balance sufficiently to permit specified self-protective settlement.
Insurer coverage defenses Must be analyzed under the Arizona rules applicable to the particular agreement and judgment. Carrier generally retains legitimate coverage defenses.
Fraud / collusion Agreement cannot be used as a fraudulent or collusive device. Agreement likewise must be free of fraud and collusion.

An insurer refusing the defense acts at its peril

Kepner gives Arizona insurers the ability to rely on clear outside coverage facts—but also makes the consequence of a wrong decision clear.

Carrier Was Correct

No defense obligation

If the actual coverage facts establish that the claim plainly falls outside the policy, the refusal may be justified.

Carrier Was Wrong

Breach consequences

If the insurer owed the defense and wrongfully refused it, the carrier can be liable for resulting contract damages and potentially other consequences under Arizona law.

Refusing to defend is materially different from reserving rights. A reservation preserves the insurer's participation in the liability defense. A refusal leaves the insured to protect itself.

Quihuis separates pure coverage facts from underlying liability facts

In Quihuis, an automobile liability dispute turned in part on who owned the Jeep involved in the crash.

Ownership was relevant both to the history of the accident and to whether the particular policy insured the vehicle.

Coverage Issue

Was the Jeep still an insured vehicle?

This was a pure policy-coverage question the insurer could litigate in the coverage action.

VERSUS
Tort Issue

Was the defendant liable for the claimant's damages?

Liability questions resolved in the underlying proceeding cannot automatically be relitigated by disguising them as coverage questions.

Quihuis preserves the distinction. Wrongful breach of the defense obligation can create damages without automatically expanding the substantive coverage purchased under the policy.

The cooperation clause does not operate in isolation

Liability policies generally require insureds to cooperate with the insurer's defense and prohibit unauthorized settlements.

Ordinarily those provisions protect the insurer's legitimate contractual right to investigate, defend and settle the claim.

But insurer conduct matters. Damron, Helme and Morris recognize that an insurer cannot materially breach or reserve critical obligations and then mechanically use the cooperation clause to prevent reasonable self-protection by the insured.

Arizona duty-to-defend workflow

Identify every liability policy. Determine which carrier potentially owes the defense.
Confirm insured status. Determine why the defendant qualifies as an insured under that policy.
Read the defense provision. Identify the precise contractual promise to defend.
Analyze the complaint claim by claim. Compare factual allegations with the policy's affirmative coverage grant.
Apply definitions and endorsements. Determine vehicle, insured, occurrence and damages status.
Analyze exclusions. Determine whether an exclusion plainly removes the potentially covered claim.
Investigate relevant outside coverage facts. Apply Kepner, Quihuis and Teufel.
Determine whether any claim remains potentially covered. If so, Arizona generally requires defense of the entire action.
Review the carrier's response. Acceptance, reservation of rights or refusal to defend.
Examine the reservation carefully. Identify every coverage defense being preserved.
Assess the insured's personal exposure. Determine the amount and nature of uncovered or excess risk.
Before settlement, apply Damron/Morris law. The insured's ability to settle depends materially on whether the carrier refused to defend or is defending under reservation.
Keep indemnity separate. Do not assume the defense ruling necessarily determines ultimate coverage.
Evaluate unreasonable conduct separately. Use Guide 09 for bad faith and Guide 12 for third-party failure to settle.

Common Arizona duty-to-defend mistakes

“No indemnity means no duty to defend.”

Wrong. Arizona expressly treats the defense duty as separate and broader.

“Only the complaint can ever be considered.”

Wrong. Kepner permits outside facts to matter when they plainly take the claim outside coverage.

“One uncovered count eliminates the defense.”

No. One potentially covered claim generally triggers defense of the entire action.

“A reservation of rights means the insurer denied the defense.”

No. A reservation ordinarily means the insurer is providing the defense while preserving identified coverage defenses.

“A Damron agreement and Morris agreement are the same.”

They arise from materially different insurer conduct and have different analytical consequences.

“Wrongful refusal to defend automatically creates coverage.”

Quihuis rejects using the defense breach simply to manufacture indemnity coverage never purchased.

Arizona authority map

Arizona Supreme Court · 1973 Kepner v. Western Fire Insurance Co., 109 Ariz. 329

Establishes Arizona's important exception to a rigid complaint-only approach: facts outside the pleading can establish that an apparently covered claim plainly falls outside the policy. An insurer refusing the defense does so at the risk that its coverage judgment may be wrong.

Arizona Supreme Court · 2018 Teufel v. American Family Mutual Insurance Co., 244 Ariz. 383

Provides a modern statement of Arizona defense law: defense is broader than indemnity, outside coverage facts can matter, and one covered claim generally requires defense against all claims in the action.

Arizona Supreme Court · 1987 United Services Automobile Association v. Morris, 154 Ariz. 113

Holds that an insured being defended under reservation may take specified reasonable steps to protect against noncoverage and personal exposure without automatically breaching the cooperation clause.

Arizona Supreme Court · 1969 Damron v. Sledge, 105 Ariz. 151

Recognizes the insured's ability to protect itself through settlement, covenant and assignment after an insurer refuses the liability defense.

Arizona Supreme Court · 1987 Arizona Property & Casualty Insurance Guaranty Fund v. Helme, 153 Ariz. 129

Identifies the fundamental insurer duties of indemnity, defense and equal consideration of settlement and explains why material insurer breach can narrow the insured's cooperation obligations.

Arizona Supreme Court · 1983 Farmers Insurance Co. of Arizona v. Vagnozzi, 138 Ariz. 443

Addresses the interaction among reservation of rights, defense, coverage litigation and issue-preclusion principles.

Arizona Supreme Court · 2014 Quihuis v. State Farm Mutual Automobile Insurance Co., 235 Ariz. 536

Reaffirms that the defense duty is broader than indemnity, confirms Arizona's use of outside coverage facts, and holds that a refusal to defend does not automatically prevent litigation of a pure coverage issue or create coverage that was never purchased.

Arizona Court of Appeals · 1981 Western Casualty & Surety Co. v. International Spas of Arizona, Inc., 130 Ariz. 76

Establishes the Arizona rule that when one claim in the action is covered, the insurer generally must provide a defense to the entire suit.

Source-control rule: use Teufel and Quihuis for the modern Arizona statement of the defense obligation, read them together with Kepner, and then use Damron, Helme and Morris when the carrier's defense position forces the insured to consider self-protective settlement.

Frequently asked questions

Is Arizona's duty to defend broader than the duty to indemnify?

Yes. Arizona repeatedly describes the liability insurer's defense obligation as separate from and broader than the ultimate duty to pay a covered judgment.

What usually triggers the duty to defend?

The duty generally arises when the complaint alleges facts that, if true, potentially fall within the liability policy's coverage.

Does Arizona use a strict four-corners rule?

No. Under Kepner, Quihuis and Teufel, reliable facts outside the complaint can sometimes establish that the claim plainly falls outside coverage.

If one claim is covered but the others are excluded, what happens?

Arizona generally requires the insurer to defend the entire action when any claim falls within the policy's defense obligation.

Does the insurer have to defend a groundless lawsuit?

Potentially yes. If the allegations fall within the defense promise, Arizona recognizes that the duty can extend to claims that ultimately prove groundless, false or fraudulent.

What is a reservation of rights?

It permits the insurer to provide the liability defense while preserving identified policy defenses that may later defeat or limit indemnity coverage.

Can an insured settle while being defended under reservation?

Under Morris, an insured may, in appropriate circumstances, enter into a protective settlement without automatically breaching the cooperation clause. Arizona imposes requirements concerning the agreement, notice and insurer rights.

What is the difference between a Damron agreement and a Morris agreement?

A Damron agreement generally arises after the insurer refuses to defend. A Morris agreement generally arises when the insurer is defending under a reservation of rights.

If the insurer wrongly refuses to defend, does it automatically have to pay the judgment?

Not necessarily. Quihuis maintains the distinction between defense and indemnity. A wrongful refusal can create breach damages without automatically creating substantive coverage the insured never purchased.

Can an insurer file a declaratory judgment action about coverage?

Yes. Arizona recognizes declaratory relief as a means of resolving insurance coverage disputes. Filing that action does not automatically erase a defense obligation that otherwise exists.

Why does the duty to defend matter to a crash victim?

The defense relationship can affect settlement control, insurer participation, the insured's excess exposure, reservation-of-rights issues, and the availability of Damron or Morris mechanisms if coverage becomes disputed.

Defense comes first; indemnity comes later.

Read the complaint. Read the complete policy. Investigate legitimate coverage facts outside the pleading. Determine whether any claim remains potentially covered. Then identify whether the insurer accepted the defense, reserved rights or refused it. That decision can determine not only who pays for the lawsuit, but who controls settlement and what protective options become available to the insured.
