STATE LAW – ARIZONA LIBRARY – GUIDE 11
Duty to Defend, Duty to Indemnify & Reservation of Rights
When an Arizona liability insurer must provide a defense, how that obligation differs from the ultimate duty to pay a judgment or settlement, what a reservation of rights does, and what happens when the insurer refuses to defend.

The duty to defend is broader than the duty to indemnify.
Arizona generally requires a liability insurer to defend when the claim, read with relevant information available to
the insurer, creates a potential for covered liability. The ultimate duty to indemnify is narrower and turns on the
actual facts establishing liability and coverage. If coverage is uncertain, the insurer may defend under a reservation
of rights while the coverage dispute is resolved.
REFUSAL TO DEFEND
Arizona repeatedly warns that an insurer refusing a defense does so at its peril. If the coverage judgment proves
wrong, the insurer may face contract consequences and, depending on the circumstances, additional exposure.
01
DEFENSE TRIGGER
Ask whether the liability claim potentially falls within coverage
Start with the complaint or claim
Identify the allegations, parties, claimed conduct, alleged damages, and the policy provisions that could potentially
respond.
Then test the policy
Match the allegations and known facts to the insuring agreement, insured definitions, exclusions, conditions,
endorsements, and applicable Arizona statutes.
KEPNER FRAMEWORK
Kepner v. Western Fire Insurance Co. is Arizona’s foundational duty-to-defend authority. The insurer ordinarily
looks to whether the claim falls within the policy, but Arizona does not apply a rigid complaint-only rule in every circumstance.
02
TWO DIFFERENT DUTIES
Defense and indemnity are not interchangeable
Duty to defend
Triggered by the potential for covered liability under the policy and relevant facts known to the insurer.
Duty to indemnify
Turns on the actual facts and liability ultimately established, together with the policy’s coverage terms.
Practical consequence
An insurer may owe a defense even though it ultimately has no obligation to indemnify the insured for the judgment.
DO NOT COLLAPSE THE ANALYSIS
A coverage defense that may ultimately defeat indemnity does not necessarily permit the insurer to withhold a defense
while the liability case is pending.
03
FACTS BEYOND THE PLEADING
Arizona permits a practical, fact-aware defense analysis
Arizona does not treat the complaint as the only possible source of information. The important question is how
allegations and relevant facts known to the insurer affect the potential for coverage.
Facts supporting potential coverage
Lennar Corp. v. Auto-Owners Insurance Co. explains that the insurer should consider relevant information
supplied outside the complaint when that information creates or confirms a potential for covered liability.
Facts plainly defeating coverage
Kepner recognizes that actual facts outside the complaint can matter when they plainly take the claim outside
coverage and are not issues that will be resolved in the liability action. Refusing a defense on that basis remains risky
if the coverage judgment is wrong.
WORKING RULE
Preserve the complaint, tender, claim file, policy, and every material fact supplied to the insurer before the defense
decision. The chronology of what the insurer knew can be central.
04
RESERVATION OF RIGHTS
A reservation permits a defense while preserving a coverage dispute
What it does
The insurer provides the defense but identifies coverage grounds it does not concede. This allows the liability case
to be defended while the parties preserve the separate insurance-coverage dispute.
What the insured should record
Preserve the reservation letter, every cited policy provision, any amendments to the insurer’s position, defense-counsel
communications concerning coverage-related conflicts, and any separate declaratory-judgment action.
MORRIS
United Services Automobile Association v. Morris recognizes that an insured defended under a reservation of
rights may, in defined circumstances and with notice to the insurer, protect itself through a settlement without
automatically violating the cooperation clause. The settlement remains subject to Arizona’s safeguards.
SEPARATE TOPIC
Detailed Morris/Damron settlement analysis belongs in CLM-040 — Settlement, Releases & Finality. This page addresses
Morris only as part of the defense/reservation-of-rights architecture.
05
REFUSAL TO DEFEND
An insurer that declines the defense assumes substantial coverage risk
Coverage may later be found
If the insurer’s coverage judgment proves incorrect, the failure to defend can produce contract consequences in addition
to the insurer’s indemnity obligations.
Protective settlement may follow
Arizona law permits insureds to protect themselves through specified settlement arrangements when the insurer wrongfully
refuses a defense or defends under a reservation, subject to the governing Damron/Morris rules.
Bad faith is a separate inquiry
Wrongly refusing a defense does not automatically establish bad faith in every case. The reasonableness and good-faith
basis for the insurer’s conduct remain separate questions.
QUIHUIS
In Quihuis v. State Farm, the Arizona Supreme Court reiterated that an insurer refusing to defend acts “at its peril”
and described defending under a reservation of rights while promptly pursuing a coverage determination as the prudent practice
when coverage is disputed.
06
PRACTICAL METHOD
Audit the defense decision in a fixed order
1
Confirm tender
Record when the insurer received the suit, demand, or other defense request and the materials supplied with it.
2
Build the complete policy
Collect declarations, insuring agreements, definitions, exclusions, conditions, and endorsements.
3
Map allegations to coverage
Identify every theory that potentially falls within the policy and every asserted coverage defense.
4
Add relevant outside facts
Record material information known to the insurer that expands or narrows the potential for coverage.
5
Classify the insurer’s response
Unconditional defense, defense under reservation, partial defense, delayed decision, or refusal.
6
Preserve the coverage position
Keep all reservation letters, denial letters, supplemental positions, declaratory pleadings, and defense-counsel information.
7
Separate defense from indemnity
Do not treat a defense determination as a final adjudication of the ultimate obligation to pay the judgment.

VERIFICATION
Formal QC before publishing a defense conclusion
- Confirm the complete liability policy and all endorsements.
- Confirm the date and contents of the defense tender.
- Preserve the complaint and all amended pleadings.
- Identify each potentially covered theory of liability.
- Identify relevant facts supplied outside the complaint.
- Record when the insurer learned each material fact.
- Preserve every reservation-of-rights and denial letter.
- Separate the duty to defend from the duty to indemnify.
- Check whether a declaratory-judgment coverage action is pending.
- Check whether a Morris or Damron agreement affects the insured’s position.
- Verify later treatment of Kepner, Lennar, Morris, and Quihuis before publishing a new proposition.
QC STATUS
The registry’s Kepner, Lennar, and Morris records were cross-checked against later Arizona authority, and Quihuis was
checked against the official Arizona Supreme Court opinion on September 26, 2026.

COMMON QUESTIONS
Questions to ask
Is the duty to defend broader than the duty to indemnify in Arizona?
Yes. Arizona authority recognizes that a potential for covered liability can trigger a defense even though the actual facts ultimately establish no covered obligation to pay the judgment.
Does Arizona look only at the complaint?
No rigid complaint-only rule should be assumed. Kepner and Lennar recognize that relevant facts outside the pleading can matter to the potential-for-coverage analysis.
Can an insurer defend and still dispute coverage?
Yes. A reservation of rights allows the insurer to provide the defense while preserving specified coverage issues for later resolution.
Does a reservation of rights automatically mean the insurer has denied coverage?
No. It means the insurer is defending while reserving identified grounds on which it may later contest indemnity or other coverage obligations.
What happens if the insurer refuses to defend and is later found wrong?
Arizona cases warn that the insurer acts at its peril. Contract consequences can follow, and the insurer may also lose control over aspects of the insured’s protective settlement, subject to the applicable Damron/Morris rules.
Does a wrongful failure to defend automatically establish insurance bad faith?
No automatic equivalence should be assumed. Breach of the defense obligation and bad faith are related but analytically distinct inquiries.
Can an insured settle while being defended under a reservation of rights?
Arizona’s Morris doctrine allows protective settlement in defined circumstances, with notice and substantive safeguards. Use CLM-040 for the specialized settlement analysis.
