*504 PER CURIAM.
In these consolidated medical malpractice cases, defendants appeal by leave granted from the trial court's denial of their motions to set aside the entry of a default in each case. In each case, the trial court held that M.C.L. § 600.2912e mandated a default for defendants' failure to timely file an affidavit of meritorious defense. We reverse and remand.
A trial court's ruling on a motion to set aside an entry of default is reviewed by this Court for abuse of discretion. Alken-Ziegler, Inc. v. Waterbury Headers Corp., 461 Mich. 219, 227, 600 N.W.2d 638 (1999). Except when grounded on lack of jurisdiction over the defendant, a motion to set aside a default or a default judgment should be granted only if good cause is shown and an affidavit of facts showing a meritorious defense is filed. MCR 2.603(D)(1); Alken-Ziegler, Inc, supra at 229, 600 N.W.2d 638. Good cause sufficient to warrant setting aside a default may be shown by a substantial irregularity or defect in the proceeding that the default is based on or by a reasonable excuse for failure to comply with the requirements that created the default. Id. at 233, 600 N.W.2d 638. In addition, the court may set aside an entry of default in accordance with MCR 2.612. MCR 2.603(D)(3).
Both defendants argue that the entry of the default itself comprised a substantial defect or irregularity in the proceeding sufficient to show good cause. Defendants rely on the absence of a specific remedy in the statute and assert that because the courts are not expressly permitted to enter a default, they therefore are prohibited from so doing. However, an entry of a default does not create a defect in the proceedings regardless of the construction of the statute. If plaintiffs are correct and the statute mandates a default, then obviously defendants' arguments fail. On the other hand, if the statute prohibits entry of a default, then the trial court made a mistake of law. In that case, the trial court's mistaken belief that it had to enter a default is not a procedural error but a legal error. Likewise, if the statute neither mandates nor prohibits a default but allows the trial court discretion in fashioning a remedy, then the entry of a default is not a "substantial defect or irregularity in the proceeding"; rather, the court's failure to exercise its power of discretion constitutes a clear abuse of discretion. Komejan v. Suburban Softball, Inc., 179 Mich.App. 41, 49, 445 N.W.2d 186 (1989). We thus hold that, under any interpretation of the statute, the entry of a default was not a substantial irregularity or defect in the proceeding.
Both defendants also argue that they had "reasonable excuses" for failing to file their affidavits on time. However, the trial court did not explore the matter because of its belief that it had no choice but to enter a default. While the record available to us may not appear to support "reasonable excuses," the fact that the trial court denied the parties the opportunity to develop the record renders premature any conclusion on the subject.
The question, then, in these cases is whether the trial court erred in believing that it was required to enter a default in a medical malpractice case where the defendant failed to file an affidavit of meritorious defense within the time limit required by statute. We review a question of statutory interpretation de novo. Wilhelm v. Mustafa, 243 Mich.App. 478, 481, 624 N.W.2d 435 (2000). The relevant statute, M.C.L. § 600.2912e, reads in pertinent part:
(1) In an action alleging medical malpractice, within 21 days after the plaintiff *505 has filed an affidavit in compliance with section 2912d, the defendant shall file an answer to the complaint. Subject to subsection (2), the defendant or, if the defendant is represented by an attorney, the defendant's attorney shall file, not later than 91 days after the plaintiff or the plaintiff's attorney files the affidavit required under section 2912d, an affidavit of meritorious defense signed by a health professional who the defendant's attorney reasonably believes meets the requirements for an expert witness under section 2169.
The only exception to the time limits in subsection 1 is given in subsection 2, which applies if the plaintiff fails to allow access to medical records as required under M.C.L. § 600.2912b(6); that exception does not apply in these cases. The use of the word "shall" indicates that the requirement of the statute is mandatory. Wilhelm, supra at 482, 624 N.W.2d 435. Therefore, a defendant violates the statute by failing to file an affidavit of meritorious defense within ninety-one days of the plaintiff's filing an affidavit of merit.
The next question is what sanction or remedy is appropriate for the violation. M.C.L. 600.2912e is silent in regard to a sanction for noncompliance with the ninety-one-day time limit, and nothing in that statute expressly permits or forbids an extension of time. In contrast, the statutory provision governing a plaintiff's affidavit of merit, M.C.L. § 600.2912d, is silent concerning possible sanctions, but it expressly allows a plaintiff to have an additional twenty-eight days in which to file the affidavit of merit if good cause is shown.[1] The previous version of M.C.L. § 600.2912e, which was amended in 1993,[2] provided that the trial court could, in its discretion, strike the defendant's answer and enter a default if the defendant failed to comply with the requirements of that section of the statute. Wilhelm, supra at 484, 624 N.W.2d 435. That provision was eliminated when the statute was amended in 1993; also eliminated was a provision allowing a defendant to extend time for good cause.
As our Supreme Court stated in Sun Valley Foods Co. v. Ward, 460 Mich. 230, 236, 596 N.W.2d 119 (1999) (Corrigan, J.):
The rules of statutory construction are well established. The foremost rule, and our primary task in construing a statute, is to discern and give effect to the intent of the Legislature. This task begins by examining the language of the statute itself. The words of a statute provide "the most reliable evidence of its intent...." If the language of the statute is unambiguous, the Legislature must have intended the meaning clearly expressed, and the statute must be enforced as written. No further judicial construction is required or permitted. Only where the statutory language is ambiguous may a court properly go beyond the words of the statute to ascertain legislative intent. [Citations omitted].
See also McKenzie v. Auto Club Ins. Ass'n, 458 Mich. 214, 217, 580 N.W.2d 424 (1998) (Taylor, J.).
The language of M.C.L. § 600.2912e unambiguously does not require or recommend any particular sanction. That does not mean, however, that no remedy is available. Where a statute creates a right or duty not found in the common law, the remedies provided in the *506 statute are exclusive unless they are plainly inadequate or where the act provides no adequate means of enforcement of its provisions. General Aviation, Inc. v. Capital Region Airport Authority (On Remand), 224 Mich.App. 710, 715, 569 N.W.2d 883 (1997). Because M.C.L. § 600.2912e provides no remedy, this Court may infer one. Id.
In response to defendants' arguments that the sanction provision eliminated by the 1993 amendment should be presumed to reflect a change in the intent of the Legislature, People v. Wright, 432 Mich. 84, 92, 437 N.W.2d 603 (1989), citing Lawrence Baking Co. v. Unemployment Compensation Comm., 308 Mich. 198, 205, 13 N.W.2d 260 (1944), we note first that we are required to begin with the statute as written. Sun Valley Foods, supra. The Legislature chose to delete the sanction provision rather than rewrite it, indicating that it intended to leave the determination of a proper remedy to the discretion of the court. Second, the amendment also eliminated the provision permitting an extension of time, indicating the Legislature's intent to require strict adherence to the time limit. We cannot give weight to one change without giving weight to the other; the overall effect of the amendment is to compel compliance with the stated time limits but to allow the courts to assess the facts and fashion an appropriate remedy. Robinson v. Detroit, 462 Mich. 439, 459, 613 N.W.2d 307 (2000). We therefore hold that M.C.L. § 600.2912e neither prohibits nor requires a default when the defendant fails to timely file its affidavit of meritorious defense.
We next turn to the court rules to consider whether the trial court had the power to enter a default. MCR 2.603(A) authorizes the court to enter a default of a defendant who fails to "plead or otherwise defend" in an action. We note that this language encompasses more than a failure to answer. Defendants argue that filing of the affidavit of meritorious defense should not be considered "pleading or otherwise defending"; but the statutory timing of filing, the language of the court rule, and the purpose of the affidavits combine to convince us that both plaintiffs' and defendants' affidavits are part of the pleadings. MCR 2.112, which includes the requirement that in a medical malpractice case "each party must file an affidavit as provided in M.C.L. § 600.2912d, 600.2912e," is entitled "Pleading Special Matters." MCR 2.112(L) (emphasis added). The term "pleadings" includes only (1) a complaint, (2) a crossclaim, (3) a counterclaim, (4) a third-party complaint, (5) an answer to a complaint, cross-claim, counterclaim, or third-party complaint, and (6) a reply to an answer; thus, defendants' affidavits are part of the answer. MCR 2.110(A). Without the affidavit, the answer is incomplete and does not conform with the rules; under MCR 2.115(B), the court may strike the answer and enter a default. In medical malpractice cases, the purpose of the affidavits is to identify valid claims and defenses meriting discovery. See VandenBerg v. VandenBerg, 231 Mich.App. 497, 502, 586 N.W.2d 570 (1998). We therefore conclude that when a defendant fails to file an affidavit of meritorious defense, that defendant has failed to plead. Thus, under MCR 2.603(A), the trial court was authorized to enter a default against defendants.
Finally, we explore the appropriateness of entering a default in this case. This is an issue of first impression for this Court because the circumstances in each of the prior relevant medical malpractice cases were slightly, but significantly, different from the present case. In Wilhelm, supra at 485, 624 N.W.2d 435, where the defendant failed to timely file the affidavit, *507 the trial court did not enter a default because the plaintiff waived the issue by not raising it until the day of trial. In VandenBerg, supra, the plaintiff filed the affidavit three months after filing the complaint, but served the defendants with both the complaint and the affidavit at the same time. This Court held that dismissal was not required by the statute and was not appropriate because the defendants suffered no prejudice. Similarly, in Dorris v. Detroit Osteopathic Hosp. Corp., 460 Mich. 26, 47-48, 594 N.W.2d 455 (1999), the plaintiff failed to file the required affidavit before serving the defendant with the complaint. Our Supreme Court held that dismissal without prejudice was proper because the period of limitation had not expired. The Court developed the law further in Scarsella v. Pollak, 461 Mich. 547, 551-553, 607 N.W.2d 711 (2000), where it held the complaint alone was insufficient to commence the plaintiff's action and the suit was time-barred because the affidavit was not filed before the period of limitation expired. Although we apply the principles from these cases to the situation at hand, we find none of them directly analogous.
Defendants argue that this case is analogous to VandenBerg, supra, and that dismissal without prejudice is appropriate. However, the defendants in a medical malpractice case are not in the same situation as the plaintiffs. First, they are not racing the statute of limitations clock; their interest in prolonging the suit is very different from the plaintiffs' need to meet the statutory deadline. Second, the statutory provisions and language applying to the defendants is similar, but not identical, to that applying to the plaintiffs; for instance, the Legislature did not grant the defendants the right to extend the time allowed. Third, to permit the defendants to delay with impunity does nothing to encourage the parties to explore the merits of the case before trial. VandenBerg, supra at 502, 586 N.W.2d 570. The cooperation of both parties is necessary for the effective development of the meritorious issues; the plaintiff is not the only party whose involvement is necessary to ascertain the validity of the allegations made. While the focus in the past has been on the intent of the Legislature to prevent plaintiffs from bringing frivolous claims, the language of the statute is equally strict in requiring defendants to present a valid defense.
We therefore find that in each of these cases, although a default was a permissible remedy, the trial court erroneously believed that it was required by statute to enter a default and that it had no discretion to fashion any other appropriate sanction. Because the trial court did not exercise discretion in entering the default and did not consider the possibility of any other remedies, it erred in refusing to set aside the default. We reverse its orders and remand for exploration of the issues of setting aside the defaults for good cause and what remedies should be ordered. We recognize that the trial court may ultimately find a default to be appropriate, but it may reach its conclusion only after exercising its own discretion in the matter. In selecting a sanction both appropriate and effective in compelling compliance with the statute, the trial court may consider the reasons for defendants' delays, what other actions defendants took to apprise plaintiffs and the court of those reasons, any prejudice to plaintiffs resulting from the delays, and any other factors relevant to the determination.
Reversed and remanded. We do not retain jurisdiction.
