Marriage of Dilsaver: An Unvacated Default Defeats a Late Answer and Limits Hearing-Notice Rights

Supreme Court of Montana | November 4, 2026 | 2026 MT 267N | No. DA 25-0807

Precedential status: This is a noncitable memorandum opinion. The Court expressly stated that it does not serve as precedent. It applies settled procedural law rather than establishing a new legal rule.

1. Introduction

Marriage of Dilsaver concerns the procedural consequences of failing to respond to a petition for legal separation. Gregory C. Dilsaver, representing himself, appealed a decree granting Michelle L. Dilsaver legal separation, adopting her proposed parenting plan, and distributing the parties’ property and debts.

Gregory advanced two principal objections: the District Court failed to consider an answer he claimed to have timely filed, and it conducted the dispositive hearing without notifying him. He argued that these failures denied him a meaningful opportunity to participate and deprived him of property without due process.

The Montana Supreme Court rejected both arguments. Its analysis turned on Gregory’s procedural status: default had been entered before he attempted to answer, that default had never been set aside, and the Court determined that he had not appeared in the proceeding. His attempted answer did not restore his right to plead, and the applicable rules did not require notice of the hearing to a defaulted party who had never appeared.

2. Background and Procedural History

Michelle filed her petition on June 6, 2025. Attempts to serve Gregory personally at the physical address he supplied to her counsel were unsuccessful because he did not reside there. Michelle subsequently served him by publication and filed an affidavit documenting publication.

Gregory did not respond within the prescribed period. On September 29, 2025, the Clerk of District Court entered his default for failing to plead or otherwise defend.

Gregory later attempted to submit an answer. According to the District Court’s findings, the document was not filed because default had already been entered, he had not paid the $70 filing fee, and he had not supplied valid contact information beyond an address where he did not reside. He did not move to set aside the default.

At the October 16, 2025 hearing, Michelle testified under oath. The District Court took judicial notice of a permanent protection order entered in her favor against Gregory. It also received testimony concerning serious marital discord and Michelle’s Montana domicile for more than ninety days before filing. The parties had married in 1998 and had eight minor children.

The court adopted Michelle’s proposed parenting plan, finding it served the children’s best interests. The plan provided that the children would reside solely with Michelle and that Gregory’s contact would be supervised and arranged by agreement between the parents. The court also adopted Michelle’s proposed allocation of real property, personal property, and debts.

Notice of entry of judgment was mailed to Gregory at his St. Marys, Kansas address on October 17, 2025. The Supreme Court treated the decree’s reference to an October 16, 2024 hearing as a clerical error and used October 16, 2025 as the hearing date.

3. Summary of the Opinion

The Supreme Court unanimously affirmed the decree. Its principal conclusions were:

  1. The record did not support Gregory’s claim of a timely answer. The District Court expressly addressed his attempted submission and found that it occurred after default.
  2. The attempted answer did not undo the default. Gregory had not obtained relief from default under the procedures identified in Rules 55(c) and 60(b).
  3. The attempted filing had additional procedural defects. The Court relied on the unpaid filing fee, inadequate contact information, and failure to satisfy the filing and service requirements discussed under Rule 5(d).
  4. Advance notice of the hearing was not required on this record. Rules 5(a)(2) and 55(b)(2) did not require that notice for a party who was in default for failing to appear and who had never appeared personally or through a representative.
  5. The asserted due process violation was not established. The Court concluded that Gregory had received notice by publication and an opportunity to respond before default.

The Court characterized the appeal as controlled by settled law and the clear application of the governing standards, warranting disposition by noncitable memorandum opinion.

4. Analysis

A. Precedents Cited

In re Marriage of O'Moore

The Court cited In re Marriage of O'Moore, 2002 MT 31, ¶ 8, 308 Mont. 258, 42 P.3d 767, for the proposition that questions of law receive de novo review. Under that standard, the appellate court independently determines whether the lower court interpreted the law correctly.

This precedent supplied the framework for reviewing the operation of the procedural rules: whether Gregory’s post-default submission could function as an answer and whether his procedural status entitled him to hearing notice. It was not cited to establish standards for distributing marital property or determining children’s best interests.

The opinion provides no extended discussion of the earlier case’s facts. Its stated role here is therefore limited to the standard of review, not a factual analogy between the two marriages.

Greenup v. Russell

The Court relied on Greenup v. Russell, 2000 MT 154, ¶ 15, 300 Mont. 136, 3 P.3d 124, for the principle that self-represented litigants may receive some latitude, but not latitude so extensive that it prejudices the opposing party. All litigants may reasonably be expected to follow procedural rules.

This authority directly answered any suggestion that Gregory’s self-represented status required the District Court to overlook the late, unfiled, and procedurally deficient answer. The Court treated reasonable accommodation as distinct from exemption from deadlines, filing requirements, and the consequences of default.

The precedent thus reinforced procedural fairness to both parties. Flexibility toward one litigant does not require the court to disregard protections and orderly procedures on which the other litigant is entitled to rely. The Court did not use this case as an independent basis for resolving the constitutional notice issue.

B. Legal Reasoning

1. The procedural sequence controlled the result

The Court organized its reasoning around a sequence: service, an opportunity to respond, entry of default, and restricted participation unless default is set aside. It applied Rule 12(a)(1)(A)’s twenty-one-day answer requirement and concluded that Gregory had not responded within the permitted time.

Rule 55(a) then required the clerk to enter default upon the demonstrated failure to plead or otherwise defend. That entry occurred on September 29, 2025, before Gregory attempted to answer.

This chronology defeated his assertion that the District Court simply ignored a timely pleading. The decree expressly considered the attempted answer and explained why it was not treated as a filed responsive pleading.

2. A late answer was not a substitute for setting aside default

The decisive omission was Gregory’s failure to seek relief from the existing default. The Court stated that, once default is entered, further pleadings cannot be filed unless default is set aside under the applicable relief procedures.

The distinction matters because an answer and a motion to set aside default serve different purposes. An answer addresses the allegations in the petition. A motion to set aside default asks the court to remove the procedural barrier created by the failure to respond. Merely attempting the first does not accomplish the second.

Because Gregory never moved to set aside default, the Court did not decide whether he could have established grounds for that relief. The opinion therefore should not be understood as rejecting a properly supported request to reopen the proceeding; no such request was before it.

3. Filing defects reinforced the default analysis

The Court also emphasized that Gregory’s submission lacked the required filing fee and adequate contact information. It cited Rule 5(d)(2), concerning delivery to the clerk or a judge who agrees to accept a document for filing, and Rule 5(d)(1), concerning a certificate of service.

These requirements distinguish preparing or tendering a document from completing the procedural acts necessary for effective filing and service. Accurate contact information also enables courts and parties to communicate reliably with litigants.

Nevertheless, the existing default remained central. Even apart from the additional deficiencies, Gregory had not obtained the relief necessary to resume pleading. The opinion does not separately explore fee-waiver procedures or every circumstance in which a filing defect might be corrected.

4. Hearing notice depended on default and appearance status

The Court relied on two complementary rules. Rule 5(a)(2) provides that no service is required on a party in default for failing to appear. Rule 55(b)(2) requires notice of an application for default judgment when the defaulted party has appeared personally or through a representative.

These provisions make appearance status important: default alone does not mean that every defaulted litigant lacks a right to notice. A party who has appeared occupies a different procedural position from a party who has never appeared.

Here, the Court determined that Gregory had not appeared and did not treat his defective post-default submission as establishing a notice entitlement. It therefore concluded that the District Court was not required to notify him of the October hearing.

The opinion does not comprehensively define what conduct may constitute an appearance in other cases. Its reasoning should not be extended to conclude that every informal communication or defective submission is necessarily irrelevant to that inquiry.

5. Due process required an opportunity to participate, not unlimited renewed opportunities

Gregory framed the decree as a unilateral deprivation of property. The Court responded that due process requires notice and an opportunity to be heard within the procedural framework. It found those requirements satisfied by publication service and the prescribed opportunity to answer before default.

The distinction is between being denied an opportunity to participate and failing to use an available opportunity. On the record accepted by the Court, Gregory’s absence from the hearing resulted from the latter.

This reasoning does not establish that default cures invalid service. The opinion accepted publication service as effective but did not provide an extensive analysis of its authorization or constitutional adequacy. Nor does the later mailing of notice of judgment independently establish that earlier service was sufficient. The Court’s conclusion rested on its determination that Gregory had been properly notified before default.

6. Affirmance did not create substantive family-law rules

The decree affected substantial interests: parenting arrangements for eight children, real and personal property, and marital debts. The hearing nevertheless included sworn testimony and an express finding that the parenting plan served the children’s best interests. The proceeding was not described as a purely ministerial acceptance of the petition.

However, the appellate analysis addressed Gregory’s procedural objections rather than independently examining the merits of particular property allocations or parenting restrictions. The opinion supplies neither detailed valuation evidence nor a substantive analysis of the supervised-contact arrangement.

Accordingly, it does not establish that default automatically makes a proposed parenting plan appropriate or a proposed property distribution equitable.

C. Potential Impact and Limits

The decision has no precedential force. Under Section I, Paragraph 3(c) of the Montana Supreme Court’s Internal Operating Rules, it may not be cited and does not establish binding authority for future cases.

Its practical lessons nevertheless reflect the existing rules it applies:

  • Prompt response matters: failure to answer can produce consequences extending beyond the missed deadline.
  • Relief must match procedural posture: after default, a litigant must address the default rather than assume a late answer restores ordinary participation.
  • Appearance affects notice: courts must distinguish a nonappearing defaulted party from a defaulted party who has appeared.
  • Self-representation does not suspend procedural rules: reasonable latitude remains bounded by fairness to the opposing party.
  • Basic filing practices matter: fees, service documentation, and reliable contact information can materially affect participation.

Future disputes involving invalid service, a qualifying appearance, a motion to set aside default, or independently challenged parenting and property determinations would present questions not resolved by this opinion.

5. Complex Concepts Simplified

Entry of default
A formal recognition that a party failed to respond or defend. It is distinct from the later judgment granting relief.
Default judgment
A judgment entered after default that determines the relief awarded. Here, the court entered the separation decree after conducting a hearing.
Setting aside default
Obtaining a court order removing default so the case can proceed with renewed participation. A late answer does not itself provide that relief.
Appearance
Participation personally or through a representative that can affect procedural rights, including notice. The Court found no qualifying appearance here.
Service by publication
Notice through publication rather than personal delivery, when legally authorized. The Court accepted it as effective in this case.
De novo review
Independent appellate review of a legal question, without deference to the lower court’s legal interpretation.
Due process
The constitutional requirement of fair procedures, including legally adequate notice and an opportunity to be heard.
Noncitable memorandum opinion
A decision resolving the parties’ appeal without creating precedent and, under the rule invoked here, without permission to cite it.

6. Conclusion

Marriage of Dilsaver illustrates the consequences of an unvacated default. Gregory’s attempted late answer did not restore his pleading rights, and his status as a defaulted party who had never appeared defeated his claim to advance hearing notice. The Supreme Court therefore affirmed the separation decree.

The decision’s significance is practical rather than precedential: meaningful participation requires timely action and, after default, use of the procedures designed to obtain relief. It creates no new rule governing property division, parenting plans, or constitutional notice.
