CONNOR, P.J.

Plaintiff appeals as of right from the trial court's order granting garnishee defendant's motion for summary disposition pursuant to MCR 2.116(C)(7) and denying plaintiff's motion for summary disposition pursuant to MCR 2.116(C)(9) and (C)(10). We affirm.

This appeal stems from an accident that occurred in September of 1988 in which Yvette Guthery was injured when her moped collided with a car driven by defendant Rodney Edwards and owned by defendant Erisline Hale. Plaintiff commenced an action against Edwards and Hale in July of 1990, and was granted a default judgment against them in April 1991. In October of 1992, plaintiff filed a writ of garnishment against garnishee defendant. One month later, garnishee defendant responded by filing a disclosure, wherein it admitted a policy existed covering defendant Hale. The disclosure also stated it was unknown whether that policy applied to any claim by plaintiff.

Plaintiff filed interrogatories, and garnishee defendant answered in November of 1992. In response to a request to expand on the reasons why the policy did not apply, garnishee defendant stated:

Garnishee Defendant does not know whether the policy is applicable to plaintiff's claims because the plaintiff has never bothered to tell Garnishee Defendant what the claim consists of.

In a response to a request to state affirmative defenses, garnishee defendant stated:

Unable to state any affirmative defenses for the reason that we have no idea what the plaintiff's claim is about. We reserve the right to provide affirmative defense once the plaintiff provides us with some basis for the claim.

Thereafter, the parties filed their motions for summary disposition.

We find the trial court did not err in granting garnishee defendant's motion for summary disposition because garnishee defendant did not have timely notice of the lawsuit and was prejudiced by the lack of notice.

The scope of residual liability insurance coverage for an accident that occurs in Michigan is determined by the Michigan financial responsibility act, MCL 257.501 et seq.; MSA 9.2201 et seq.; Kleit v Saad, 153 Mich. App. 52, 56; 395 N.W.2d 8 (1985). The section of the act addressing the liability of an insurer in an action by a judgment creditor provides:

The insurance carrier shall not be liable on any judgment if it has not had prompt notice of and reasonable opportunity to appear in and defend the action in which such judgment was rendered. . . . [MCL 257.520(f)(6); MSA 9.2220(f)(6).]

The Kleit Court held that the failure of an insured to notify its insurer, the garnishee defendant, of the lawsuit relieves the garnishee defendant of liability. Kleit, supra, 57. Thus, in order for a garnishee defendant insurer to be relieved of liability because of lack of notice, it (1) must not have received timely notice of the lawsuit, and (2) must have been prejudiced by the lack of notice. Id. at 57-58.

In the present case, it is undisputed that garnishee defendant did not receive notice of the lawsuit until the filing of the writ of garnishment in October of 1992, which was seventeen months after the entry of the default judgment and twenty-seven months after the filing of the complaint. Accordingly, we deem the notice untimely.

The affidavits submitted by both parties below reveal that a claims adjuster for plaintiff's insurer contacted garnishee defendant and inquired into coverage of defendant Hale in September of 1988, but did not file a claim. Thereafter, in March of 1989, the claims adjuster contacted the agent of record and was told that defendant Hale was covered by garnishee defendant under a policy different from that about which garnishee defendant informed the claims adjuster. We conclude that these March 1989 contacts were insufficient to mitigate the prejudice caused by the lack of timely notice. Delays in notification can prejudice an insurer when the insurer is prevented from investigating the accident. Kleit, supra, 58; Henderson v Biron, 138 Mich. App. 503, 506-507; 360 N.W.2d 230 (1984). While garnishee defendant may have been able to infer from the call that an accident had taken place, there was no indication that a claim or a lawsuit was planned. Summary disposition was properly granted in favor of garnishee defendant.

Plaintiff obtained a valid default judgment against garnishee defendant's insured. However, because garnishee defendant presented a valid defense to liability, specifically, lack of timely notice, the trial court correctly denied plaintiff's motion for summary disposition pursuant to MCR 2.116(C)(10).

Finally, we find the trial court properly denied plaintiff's motion for summary disposition pursuant to MCR 2.116(C)(9). In a disputed garnishment action, the garnishment affidavit serves as the complaint and the disclosure serves as the answer. MCR 3.101(M)(2). The issues in a garnishment dispute are to be tried in the same manner as other civil actions. MCR 3.101(M)(1). Plaintiff infers from this rule that a garnishee must plead its defenses in the disclosure or waive them as dictated by MCR 2.111(F)(2). Case law not cited by plaintiff supports this proposition. See Westland Park Apartments v Ricco Inc, 77 Mich. App. 101, 104; 258 N.W.2d 62 (1977), citing Clark v Hacker, 345 Mich. 751, 755-756; 76 N.W.2d 806 (1956).

However, the court rule regarding the contents of a disclosure requires only that the garnishee reveal its liability to the principal defendant and claim any setoff. MCR 3.101(H)(1)(a). Moreover, MCR 3.101(M)(2) provides, "[e]xcept as the facts stated in the verified statement are admitted by the disclosure, they are denied." Accordingly, a general denial of liability is sufficient to preserve a garnishee defendant's right to litigate its liability. Admiral Ins Co v Columbia Casualty Ins Co, 194 Mich. App. 300, 309; 486 N.W.2d 351 (1992).

We find that absent an admission to the contrary in the disclosure, the failure to plead specifically a defense does not waive the defense. In the present case, the disclosure filed by garnishee defendant acknowledged the existence of a policy covering its insured, but stated, "[i]t is unknown by garnishee defendant whether said policy applies to any claim by the Plaintiff." Because garnishee defendant could not determine its defenses until the facts underlying the dispute were developed and an amendment of the pleadings would have corrected any deficiency, plaintiff's motion was properly denied.

Affirmed.
