Petitioner appeals as of right from an order quashing her petition for allowance of a disputed claim and denying her petition for leave to file a delayed claim that requested leave to amend the petition. We reverse and remand.

background

Petitioner cared for Reverend Robertson Gordon from 1986, when he was paralyzed by a stroke, until his death on March 30, 1993. On July 14, 1993, petitioner filed against the estate a claim for services rendered. The personal representative sent a notice of disallowance of the claim on December 2, 1993, and again on December 13, 1993. The notices advised petitioner that her claim would be disallowed unless “you start a civil action by filing a complaint against the fiduciary. Your complaint must be filed with a district, *150circuit or probate court not later than 63 days after the mailing of this notice.” On January 28, 1994, petitioner filed a “petition for allowance of disputed claim” with the probate court. The personal representative then filed a motion to quash the petition, arguing that petitioner failed to commence a civil action by complaint, as required by § 717(1) of the Revised Probate Code (hereafter rpc) and the probate court rules. MCL 700.717(1); MSA 27.5717(1); MCR 5.101. In her reply, petitioner urged that her petition conformed with the RPC and court rule, but also requested leave to amend her petition to cure any alleged procedural defects.

Following a hearing, the probate court quashed the petition, holding that petitioner’s pleading did not conform with the procedural requirements in the RPC and court rule. The court then dismissed her claim in its entirety, concluding that, because petitioner’s timely filed petition had been quashed and the limitation period had passed by the time of the hearing, petitioner could not now contest the notice of disallowance within the time permitted. The court also denied petitioner’s request for leave to amend, reasoning that the RPC did not authorize the court to extend the time for filing a claim after the time for filing the claim had expired.

On appeal, petitioner argues that her petition for allowance of a disputed claim was authorized by § 717(1) and MCR 5.101(C). Alternatively, petitioner argues that the probate court should have allowed her to amend her petition to correct any technical defects because the personal representative had notice of the nature of her claim.

*151The personal representative responds that dismissal of the petition was proper because both the RPC and the court rule require filing a complaint. It is the personal representative’s contention that the procedural requirements in the court rule supersede the RPC procedural provisions, emphasizing further that MCR 5.101(C) clearly states that a civil action must be filed in response to a notice of disallowance. Similarly, the personal representative maintains that the RPC also required that petitioner file a complaint once petitioner received notice of disallowance that “warned of the impending bar” to her claim. See MCL 700.717(1); MSA 27.5717(1). Finally, and alternatively, the personal representative contends that petitioner’s action was properly dismissed for failure of service.

A

PROCEDURAL CONFLICT: § 717(1) VERSUS MCR 5.101(C)

Under the RPC, after the personal representative receives a creditor’s claim against the estate, the personal representative is authorized to disallow the claim by mailing a notice of disallowance to the claimant. MCL 700.717(1); MSA 27.5717(1). The notice of disallowance effectively bars the claim against the estate unless the claimant acts to contest the notice. Id. Section 717(1) provides that a claimant may contest the disallowance by petitioning the court to allow the claim or by commencing a proceeding against the personal representative not later than sixty-three days from the date the notice of disallowance was mailed, if the notice “warns the claimant of the impending *152bar.”1 MCL 700.717(1); MSA 27.5717(1). Thus, the RPC provides a claimant with two alternative procedures in the event the personal representative disallows a claim.2

By contrast, MCR 5.101(C) requires that after a notice of disallowance has been issued, a petition filed by a claimant must be titled a “civil action” and *153commenced by filing a “complaint.”3 Further, the rule provides that the filing of such an action is governed by the court rules applicable to civil actions in the circuit court. MCR 5.101(C). The rule effectively eliminates one of the RPC alternatives (i.e., filing a petition with the court to contest a disallowed claim), thus creating a direct conflict between § 717(1) and the court rule.

Conflict between the procedural rules of the court rule and the RPC raises an issue of first impression — Is a claimant’s response to a personal representative’s notice of disallowance governed by § 717(1) or by MCR 5.101(C)?

Generally, the Supreme Court’s rule-making power is constitutionally supreme in matters of practice or procedure. Const 1963, art 6, § 5. However, the Supreme Court’s rule-making power is constitutionally supreme in matters of practice and procedure only when the conflicting statute embodying putative procedural rules reflects no legislative policy consideration other than judicial dispatch of litigation. 3 Honigman & Hawkins, Michigan Court Rules Annotated (2d ed), p 404; Kirby v Larson, 400 Mich 585, *154598; 256 NW2d 400 (1977) (Williams, J.). Thus, while purely procedural matters are constitutionally delegated to the Supreme Court, a court rule promulgated by that Court cannot intrude upon substantive legislated policy matters such as the restriction or expansion of the jurisdiction of the probate court. In re Hillier Estate, 189 Mich App 716, 719; 473 NW2d 811 (1991); see also In re Kasuba Estate, 401 Mich 560, 566; 258 NW2d 731 (1977) (the Supreme Court cannot expand the jurisdiction of the probate court without legislative consent). Consequently, in resolving the conflict between the court rule and the RPC, our task is to determine whether the procedures prescribed in the rpc reflect a substantive legislative policy beyond “judicial dispatch of litigation.” Kirby, supra.

The conflict between the rpc and the court rule was created after the Legislature amended the rpc in 1989 to expand the probate court’s jurisdiction to include concurrent jurisdiction with the circuit court over civil claims. 1989 PA 69, MCL 700.21; MSA 27.5021, MCL 700.22; MSA 27.5022. The Legislature failed to amend the procedural requirements specified in § 717(1) to conform with the new jurisdictional amendments. To fill the breach, the Supreme Court amended the probate court rules in 1992 in recognition of the probate court’s expanded jurisdiction. 439 Mich clxii; see also Comment to MCR 5.101.4 Specifically, MCR 5.101 was modified to recognize two types of actions that could be conducted in the probate court (“proceedings” and “civil actions”) and, as noted above, to extend application of the circuit court *155rules to civil claims that would now be litigated in probate.5 MCR 5.101(A), (C).

The RPC provisions at issue do not address jurisdictional issues or any other identifiable substantive legislative policy consideration, but merely procedural issues concerning how to initiate the probate court’s review of a disallowed claim. Moreover, the amendments of MCR 5.101 do not touch upon substantive or jurisdictional issues and are consistent with procedural considerations attendant to the legislative expansion of the probate court’s jurisdiction to litigate civil claims. Consequently, we hold that the court rule governs the procedure to be followed when a claimant responds to a notice of disallowance by the personal representative. Thus, the court rule supersedes the RPC procedural requirements such that a petition filed after a notice of disallowance must be labeled a “civil action” and a complaint must be filed in accordance with MCR 5.101(C).

DISMISSAL Of PETITIONER’S PETITION

Although petitioner’s petition, on its face, does not conform with MCR 5.101(C), we hold that it was improper for the probate court to quash petitioner’s pleading for these procedural defects. MCR 5.101(C) provides that the “civil actions” concerning claim dis-allowance disputes now legislatively authorized to be litigated in the probate court are governed by the *156court rules applicable to actions brought in the circuit court. Accordingly, under those rules, a party filing a defective pleading can seek leave to amend the pleading. See MCR 2.118. MCR 2.118(A) provides that “leave to amend shall be freely given where justice requires.”

Petitioner’s pleading was labeled a “petition,” but it was drafted in the form of a civil complaint, which included one count of oral contract, another count of implied contract, and a jury demand. Also, petitioner requested leave to file a delayed claim pursuant to MCL 700.712(2); MSA 27.5712(2). Though made under the procedure set forth in the RPC, petitioner’s request was consistent with a request to amend pursuant to MCR 2.118 and should have been treated as such by the probate court. This is particularly so, because, in her request, petitioner sought leave to correct the procedural defects in her petition, arguing that her pleading was timely filed and that the personal representative had not been prejudiced by the alleged procedural defects. Significantly, when denying the petitioner’s request for leave to amend, the probate court found that petitioner, in good faith, filed a pleading within the time limitation prescribed, that dismissal of the petition would be unjust, and that the personal representative had not been prejudiced by the defects in the petition.6 Therefore, petitioner’s request to *157amend to cure the defects in her original petition should have been granted under MCR 2.118(A).7

DEFECTIVE SERVICE

The personal representative alternatively maintains that petitioner’s pleading should have been dismissed because she failed to serve a summons with a complaint in the manner prescribed by MCR 2.105. Generally, defective service of process will not warrant dismissal of a party’s pleading unless the service failed to notify the defendant of the action “within the time prescribed for service.” MCR 2.105(J)(3). However, a complete failure of service, e.g., failure to serve the *158summons with the complaint within the time for service, warrants dismissal for improper service of process. Holliday v Townley, 189 Mich App 424, 426; 473 NW2d 733 (1991). Still, a party who enters a general appearance and contests a cause of action on the merits submits to the court’s jurisdiction and waives service of process objections. Penny v ABA Pharmaceutical Co (On Remand), 203 Mich App 178, 181; 511 NW2d 896 (1993).

There is no dispute that the personal representative was notified of the action within the time prescribed. Disputed facts remain regarding whether the absence of a summons was due to petitioner’s act or omission,8 or whether the personal representative, as the administrator of a probated estate, has submitted to the court’s jurisdiction.9 Consequently, on remand, the probate court must review whether any defects in service can be excused or whether dismissal without prejudice is warranted in accordance with MCR 2.102(E).

*159We reverse and remand for proceedings consistent with this opinion. We do not retain jurisdiction.
