This action arises out of an accident on October 11, 1977, in which an automobile driven by Kathleen Flaherty collided with a truck driven by Nelson Verbeek. Both drivers were killed. Citizens Insurance Company of America was Verbeek’s primary insurer under a policy with a liability limit of $100,000. Celina Mutual Insurance Company was Verbeek’s insurer under a policy which made Celina responsible for liability in excess of that covered by Citizens’ policy up to a limit of $1,000,000. The parties settled for $265,000, including costs and interest, in an action brought by the estate of Flaherty against the estate of Verbeek. In this action, Celina sought to recover from Citizens the interest included in the settlement of the other action attributable to Citizens’ $100,000 liability. Citizens sought by counterclaim to recover from Celina the interest on its $100,000 accruing after an offer of judgment it made and a portion of its costs and actual attorney fees incurred in the defense of the action. After a nonjury trial on stipulated facts, the circuit court denied recovery to either party. Celina appeals by right, and Citizens cross-appeals.
In
Denham v Bedford,
In
Commercial Union Ins Co v Shelby Mutual Ins Co,
The language of a stipulation may not be construed to effect the waiver of a right not plainly intended to be relinquished.
In re Cole Estate,
In
Michigan Milk Producers Ass’n v Commercial Union Ins Co,
We do not agree with the result in
Michigan Milk Producers.
It is contrary to earlier Michigan cases such as
Cates v Moyses,
Citizens argues that Celina should be liable for the prejudgment interest accruing after its offer of *660 judgment was made. However, the offer of judgment by Citizens provided:
"Now come the defendants, by their attorneys, Hill-man, Baxter & Hammond, and pursuant to the terms of Rule 519.1 of the Michigan General Court Rules of 1963 offer to allow judgment to be taken against them in favor of the plaintiff, Daniel Flaherty, executor of the estate of Kathleen Mary Flaherty, deceased, in this matter for the sum of one hundred thousand and 00/ 100 ($100,000.00) dollars, including interest and costs accrued to the date of this offer.” (Emphasis added.)
A subsequent letter sent by Citizens to the counsel for the estate of Flaherty provided:
"By your letter of December 19, you indicate that you would have your client accept the $100,000.00 payment by Citizens in advance of trial, but allow absolutely no consideration for that, including the waiving of interest or costs on that portion. In light of that position, together with the continued insistence by Celina on Citizens providing a defense, there is absolutely no reason for Citizens to pay you $100,000.00.” (Emphasis added.)
The emphasized language, when read in light of Denham v Bedford, shows that Citizens did not offer its policy limits. Citizens therefore cannot claim that subsequent accrual of prejudgment interest was caused by Celina. We note that this is not a case in which the evidence shows that bad faith or negligent conduct on the part of either insurer unnecessarily prolonged the underlying action.
Citizens also argues that Celina should pay part of its costs and attorney fees. In
Aetna Casualty & Surety Co v Certain Underwriters at Lloyds of London, England,
56 Cal App 3d 791; 129 Cal Rptr
*661
47 (1976), the Court applied the principle of equitable subrogation to hold that a primary insurer continued to defend the insured against liability in excess of that covered by its policy was entitled to reimbursement from the excess insurer. An analogous issue is presented in
Foremost Life Ins Co v Waters (On Remand),
Cases from other jurisdictions besides California holding that the primary insurer is entitled to contribution from the excess insurer where both have a duty to defend include
Universal Underwriters Ins Co v Wagner,
367 F2d 866 (CA 8, 1966);
American Fidelity Ins Co v Employers Mutual Casualty Co,
3 Kan App 2d 245;
*662
Here, Celina’s policy obligated it to defend the insured if the primary coverage was exhausted. However, an insurer’s obligation to defend does not depend on its eventual liability to pay; it must defend when the pleadings show that the action is within the policy coverage,
Guerdon Industries, Inc v Fidelity & Casualty Co of New York,
We recognize that ordinarily an insurer has no duty to defend an insured absent a request to defend. See
American Mutual Liability Ins Co v Michigan Mutual Liability Co,
We hold that Celina must pay a pro-rata share of the cost of defense, including attorney fees, based on the amount of the settlement it was required to pay. On remand, the circuit court shall determine the amount of interest this opinion requires Citizens to pay and the amount of the cost of defense this opinion requires Celina to pay.
Reversed and remanded for further proceedings consistent with this opinion. We retain no jurisdiction.
