This petition for review asks us to determine whether there are genuine issues of material fact precluding summary judgment on insurance questions of duty to defend, breach of a cooperation clause and substantial prejudice to an insurer. We granted review to clarify several matters of statewide importance. Rule 23, Ariz.R. Civ.App.P., 17A A.R.S. We have jurisdiction under Ariz. Const, art. 6, § 5(3) and A.R.S. § 12-120.24.
FACTUAL AND PROCEDURAL SUMMARY
The operative facts are undisputed. William G. Holt paid insurance agent Vince Anderson for liability insurance on Holt’s automobiles. Anderson accepted the money but failed to either procure the requested coverage or tell Holt that the policy had not been issued. At the time, Anderson was covered for his professional errors and omissions as an insurance agent under a policy issued by Utica Mutual Insurance Company (Utica).
Subsequently, while driving the family car, Holt’s son was involved in an accident with Louis Mendicino. Mendicino was injured in the mishap and sued father and son for damages. Holt notified Anderson that a lawsuit had been filed and demanded that the responsible insurance carrier tender a defense and cover any losses.
Of course, no automobile insurer came forward to defend the Holts. On June 24, 1982, the Holts sued Anderson for negligently failing to obtain liability coverage for the family cars. They sought indemnity for any loss they might sustain in the Mendicino suit, attorney’s fees and an accounting for premiums paid. Their attorney spoke with Utica representatives and then wrote Utica, confirming that the Holts had sued Anderson. He enclosed a copy of the Holts’ complaint against Anderson, and asked Utica to defend the Holts in the Mendicino action. Utica did not respond or make any appearance in the Mendicino case.
On September 7, 1982, the superior court entered a default judgment for $45,000 plus costs in favor of Mendicino and against the Holts. This was apparently the result of some type of “Damron agreement” between Mendicino and the Holts.
See Damron v. Sledge,
The Holts served a writ of garnishment on Utica on February 19, 1985, claiming that Utica was indebted to Anderson as an insurer or indemnitor. After Utica answered the writ denying any indebtedness, the Holts moved for summary judgment, claiming that Utica’s only “defense” was Anderson’s supposed breach of the cooperation clause. The breach consisted of Anderson’s failure to notify Utica of the proposed entry of default judgment in favor of the Holts. According to the Holts, this defense was untenable, primarily because it contradicted the holding of
Sandoval v. Chenoweth,
Utica responded and filed a cross-motion for summary judgment, asserting that Anderson’s noncooperation abrogated Uti-ca’s duty of indemnification. Denying the relevance of Sandoval, Utica alleged that Anderson had breached his obligations to his carrier by not notifying Utica of actual service of the Holts’ complaint nor asking Utica to defend him. Instead, Anderson retained separate counsel and then gave his written consent to the entry of a default judgment, all in “apparent collusion” with the Holts.
The trial court granted the Holts’ motion for summary judgment, denied Utica’s cross-motion and entered judgment against Utica for $45,045 plus interest. Utica appealed.
BEFORE THE COURT OF APPEALS
The court of appeals transposed the results reached below.
Holt v. Utica Mutual Insurance Co.,
THE ISSUES
In essence, the Holts contend that there are three genuine issues of material fact precluding summary judgment in favor of Utica.
1
Rule 56(c), Ariz.R.Civ.P., 16 A.R.S.;
Nicoletti v. Westcor, Inc.,
1. Whether Utica breached its contractual duty to defend Anderson.
*481 2. Whether Anderson violated the cooperation clause.
3. Whether Anderson’s conduct substantially prejudiced Utica.
We must consider a fourth issue argued in the court of appeals before we can resolve any of the issues raised in this court. In the trial court and the court of appeals, the Holts argued that they were entitled to summary judgment even if Anderson had breached the cooperation clause of the Uti-ca policy because under Arizona law no breach of a cooperation clause by an insured will defeat or void an insurance policy. We first consider this threshold question.
DISCUSSION
A. Was Breach of the Cooperation Clause a Defense Available to Utica?
We agree with the court of appeals that the
Sandoval
doctrine is inapplicable and that Utica could raise Anderson’s breach of the cooperation clause as a defense.
See
Thus, an insured’s breach of policy conditions, including the cooperation clause, might be a defense to an action on the policy.
See
8 J. APPLEMAN, INSURANCE LAW AND PRACTICE § 4815 (1981). Arizona has recognized this principle in previous cases.
See, e.g., Arizona Property & Casualty Insurance Guaranty Fund v. Helme,
Under the present facts, therefore, Utica could raise its insured’s breach of the cooperation clause as a possible defense to an action on the policy. The trial court’s order of January 3, 1986, granting the Holts’ motion for summary judgment, does not specify the grounds upon which it is based. Given the arguments made in the motion, it is possible that the trial court granted summary judgment in favor of the Holts on the theory that a cooperation clause defense was unavailable to Utica as a matter of law. The order does indicate that the trial court took the motions under advisement and “after review of the pleadings as well as Sandoval v. Chenoweth,” granted the Holts’ motion for summary judgment. See Minute Entry dated Jan. 3, 1986. Based upon the court’s implicit reliance on Sandoval and the lack of any other articulated explanation for the court’s ruling, we must approve the court of appeals’ reversal of the trial court’s summary judgment in favor of the Holts.
We therefore turn to the propriety of the court of appeals’ remand of the case with instructions that the trial court grant Uti-ca’s motion for summary judgment.
B. Was Utica Entitled to Summary Judgment?
1. Utica’s Breach of the Duty to Defend
Before we can decide whether Anderson breached his duty to cooperate, we must decide whether such a duty existed. The policy clause in question requires the insured to cooperate with Utica in the defense of any liability lawsuit. Ordinarily, Anderson’s consent to the entry of judg
*482
ment would be a breach of the clause.
See Helme,
Utica had a contractual duty to defend Anderson against the Holts’ errors and omissions claim. If Utica breached that duty, Anderson had the right to fend for himself in resolving the Holts’ lawsuit against him.
See Helme,
In general, the trier of fact must determine whether a liability insurer has breached the duty to defend.
See, e.g., United States Fidelity & Guaranty Co. v. Powercraft Homes, Inc.,
The facts before us are unusual. Claims of breach of the duty to defend normally arise after the insured asks the insurer to defend and the company declines to act.
See generally
Annotation,
Liability insurer’s waiver of right, or estoppel, to set up breach of co-operation clause,
The cross-motions for summary judgment leave many factual issues unanswered. An affidavit attached to the Holts’ motion establishes that the lawyer defending the Holts against Mendicino’s personal injury damage claim had several discussions with Utica’s representatives. The affidavit states that the lawyer described the situation, explained that Anderson had improperly failed to obtain insurance coverage for the Holts, stated that the Holts could not afford to defend against Mendicino, and suggested that Uti-ca could mitigate its own damages and obviate the necessity of the Holts’ suing Anderson if it simply defended the Holts in the personal injury action. The affidavit states that Utica never offered a defense in Mendieino’s action.
Nor do Utica’s motion papers explain why Utica did nothing in the Anderson action. The motion papers show that the Holts sued Anderson after Mendicino took judgment against them. Before the Holts served process on Anderson, their attorney sent a copy of the complaint to Utica with a cover letter explaining why the Holts had sued Utica’s insured. Utica does not contend that it failed to receive these papers. An affidavit from Utica’s senior claims supervisor states only that Utica “did not receive from Vincent Anderson, any written or oral notice that he had been served” in the action (emphasis added). Utica does not claim that it informed Anderson that Utica would appear in the action only after personal service on him, or even that it would defend at all. Utica does not contend that it ever contacted Anderson after it learned that suit had been filed against him, nor does it explain why it failed to do so. In the pleadings before the trial court, Utica’s lawyers claimed that the reason for its inaction was that Utica was preserving Anderson’s right to be personally and formally served with process.
We do not find this argument so persuasive that, as a matter of law, it justifies Utica’s inaction. Even absent an ex
*483
press refusal to defend, an unreasonable delay in taking action after receiving notice of a claim may constitute a breach of the duty to defend.
See, e.g., Otteman v. Interstate Fire & Casualty Co.,
Utica’s inaction may have been a repudiation of a present duty to protect its client or it may have been an anticipatory breach of the future obligation to defend Anderson.
See Helme, supra;
17 Am.Jur. 2d
Contracts
§§ 443, 448 (1964). On the other hand, Utica’s laissez-faire attitude might merely reflect corporate ineptitude. We cannot decide as a matter of law whether Utica’s conduct could reasonably have been taken as a manifestation that it had no intent to perform under the terms of its liability contract with Anderson.
See Diamos v. Hirsch,
2. Anderson’s Violation of the Cooperation Clause
The Utica liability insurance contract contained a standard cooperation clause, which provided:
The insured shall cooperate with [Utica] and at [Utica’s] request ... shall assist ... in the conduct of suits and defense thereof. The insured shall not, except at his own cost, make any admission of liability ... assume any obligation or incur any expenses without the written consent of [Utica].
Utica argues that Anderson breached this clause by failing to notify the company when he received the Holts’ complaint, by failing to ask Utica to defend him, by retaining separate counsel and by giving his written consent to entry of a default judgment. The Holts counter that Anderson rightfully took steps to protect himself when Utica breached the contract by declining to defend him.
An insurance cooperation clause protects the insurer’s right to a fair adjudication of the insured's liability, preventing collusion between the injured person and the insured. 8 J. APPLEMAN,
supra
§ 4771, at 213. Normally, if an insured breaches the cooperation clause, a prejudiced insurer is relieved from liability under the insurance policy.

Annotation,
Liability insurance: insured’s submission to service of process as breach of co-operation clause,
Whether an insured has justifiably contravened the cooperation clause is an intensely factual question. The determination depends first upon a breach of the insurer’s duty to defend, and second upon the propriety of the insured’s consequent prophylactic measures.
See Helme,
As noted earlier, in the present case there are genuine issues of material fact whether Utica breached its duty to defend. Further, it is unclear whether Anderson’s actions were a properly measured response to Utica’s inaction. 2 That question must be resolved by factual inquiry, and not by legal induction. Based on the record before us, summary judgment in favor of either party on the issue of breach of the cooperation clause was improper.
3. Substantial Prejudice to the Insurer
Even if an insured breaches a cooperation clause, the insurer may not use that fact as a defense unless the breach has caused substantial prejudice.
See generally
Annotation,
Modem status of mies requiring liability insurer to show prejudice to escape liability because of insured’s failure or delay in giving notice of accident or claim, or in forwarding suit papers,
The court of appeals concluded that Anderson’s alleged breach of the cooperation clause had caused substantial prejudice to Utica as a matter of law.
The record on this question also is too sparse to permit adjudication of this case as a matter of law. Anderson failed to provide the Holts with the insurance policy which they had purchased. As a result, the Holts were uninsured against Mendicino’s claim. Mendicino obtained a default judgment against the Holts in the amount of $45,000, plus $45 court costs. Utica had an opportunity to appear for the Holts in that action to protect its interests and mitigate damages. Utica apparently chose not to do so. It is not now in a position to make a collateral attack on the Mendicino judgment against the Holts. Blomfield, supra.
Thus, if Anderson was negligent in failing to provide the Holts with the promised policy, then he is apparently liable to the Holts in the sum of $45,045, the exact amount of the Holts’ consent judgment against Anderson. Therefore, even assuming that Anderson breached the cooperation clause by failing to notify Utica that he had actually been served and by allowing the Holts to take judgment, this record does not show how Utica suffered any prejudice. We disagree that “prejudice automatically follows from , the denial” of an opportunity to defend against a claim.
CONCLUSION
The three factual issues posed by the Holts must be resolved at the trial court level. The record does not allow their disposition by summary judgment. We vacate the court of appeals’ opinion and re *485 verse the trial court’s summary judgment. We remand for further proceedings consistent with this opinion.
Notes
. The Holts have not sought review of the court of appeals’ ruling that Utica could challenge the default judgment against Anderson at the garnishment hearing.
See
Annotation,
Liability insurer’s right to open or set aside, or contest matters relating to merits of, judgment against insured, entered in action in which insurer did not appear or defend,
. We note that the record contains no explanation of why neither the Holts' nor Anderson’s attorney apparently made any attempt to contact Utica and ascertain its position between the date a copy of summons and complaint in Holt v. Anderson was sent to the insurer and the date on which the insurer finally learned of entry of the default judgment. Utica argued that there had been obvious collusion to deprive the company of its right to an adjudication of its insured’s liability. Resolution of that issue must also await a fuller exposition of the facts.
