Unauthorized Partner Consent Cannot Create Personal Jurisdiction Over an Out-of-State Partnership (Rule 60(b)(4) Vacatur of Domesticated Foreign Judgment)

Case: In the Matter of the Estate of Ann Lafferty Pfeifer-Murphy, Deceased, 2026 MT 136 (Mont. June 30, 2026)
Court: Supreme Court of Montana
Core holding: A foreign judgment domesticated in Montana must be vacated as void under M. R. Civ. P. 60(b)(4) when the rendering court lacked personal jurisdiction, and purported “consent” by a partner binds the partnership only if within the ordinary course of business or authorized/ratified under § 35-10-301, MCA.

1. Introduction

Estate of Pfeifer-Murphy arises from Idaho probate litigation in which the Estate’s beneficiaries sought to recover substantial funds misappropriated by Karin Cook (the Idaho-appointed personal representative) to benefit herself, her husband Gerald Cook, and their company Pneumex, Inc. The controversy reached Montana when an Idaho judgment—entered by stipulation and later domesticated in Montana—was enforced against a separate entity: the Cook-Reynolds Partnership (CRP), a Montana farmland partnership co-owned by Gerald and Linda Reynolds (the managing partner).

The central legal question was jurisdictional: Did the Idaho court have personal jurisdiction over CRP, an out-of-state partnership with no Idaho business, where Gerald (without Linda’s authorization) signed a settlement and stipulation purportedly consenting to Idaho jurisdiction and confessing liability on CRP’s behalf? A second, closely related question addressed the procedural gatekeeping for setting aside judgments: Was CRP’s Rule 60(b)(4) motion made “within a reasonable time” despite being filed about four years after the Idaho judgment was entered?

New operational rule crystallized by the Opinion

  • No “consent-by-rogue-partner” jurisdiction: A partner’s purported consent to personal jurisdiction and confession of judgment against the partnership does not bind the partnership if the conduct was outside the ordinary course of partnership business and was not authorized or ratified under § 35-10-301(2), MCA.
  • No res judicata shield absent real litigation: Even though res judicata can apply to jurisdictional questions, Montana courts may collaterally examine personal jurisdiction when the issue was not “fully and fairly litigated” in the rendering court.
  • Reasonable-time flexibility for voidness challenges: A multi-year delay may still be “within a reasonable time” under M. R. Civ. P. 60(c)(1) for Rule 60(b)(4) relief when the movant lacked meaningful notice/knowledge and the judgment creditor shows no prejudice.

2. Summary of the Opinion

The Montana Supreme Court reversed the District Court’s deemed denial of CRP’s Rule 60(b)(4) motion and held the Idaho judgment void as to CRP for lack of personal jurisdiction. The Court vacated the portion of the domesticated Idaho judgment that imposed joint-and-several liability on CRP, while leaving the judgment intact against the other debtors (including Karin, Gerald, and Pneumex-related entities).

The Court reasoned that: (1) Idaho personal jurisdiction over an out-of-state partnership required satisfaction of Idaho’s long-arm statute or a valid voluntary appearance/waiver; (2) Gerald lacked authority under CRP’s Partnership Agreement (and Montana partnership law) to submit CRP to Idaho jurisdiction or confess liability; (3) Linda did not ratify Gerald’s acts; (4) without business contacts or tortious acts in Idaho attributable to CRP, Idaho’s long-arm statute was not met; and (5) CRP’s four-year delay in seeking Rule 60(b)(4) relief was reasonable given lack of prejudice to the Estate and Linda’s testimony about not learning of the judgment until enforcement began.

3. Analysis

3.1 Precedents Cited (and how they shaped the result)

A. Rule 60(b)(4) framework and standard of review

  • Essex Ins. Co. v. Moose's Saloon, Inc. — Established that the standard of review depends on the Rule 60(b) ground, and that voidness under Rule 60(b)(4) is reviewed de novo as a legal conclusion. This case underwrote the Court’s independent, non-deferential re-examination of jurisdiction.
  • Flathead Lakers Inc. v. Mont. Dep't of Nat. Res. & Conservation — Confirmed that a deemed denial is still reviewable “for error on its merits,” allowing the Supreme Court to address the substance even though the District Court failed to rule within the time constraints.
  • Greater Missoula Area Fed'n of Early Childhood Educators v. Child Start, Inc. — Reinforced the principle that a judgment is “void” under Rule 60(b)(4) when the court lacked jurisdiction, anchoring the remedy CRP sought.
  • Koch v. Billings Sch. Dist. No. 2 — Confirmed the “reasonable time” requirement for Rule 60(b)(4) motions under Rule 60(c)(1), framing the timeliness inquiry as fact-sensitive rather than a strict deadline.

B. Foreign judgments, collateral attack, and the UEFJA

  • Carr v. Bett — A cornerstone for Montana’s treatment of foreign judgments: Montana must give full faith and credit, but a foreign judgment may be challenged for invalidity, including lack of personal jurisdiction; a Rule 60(b) motion is the appropriate procedural vehicle; and § 25-9-503, MCA (UEFJA) permits such challenges. The Court in Estate of Pfeifer-Murphy essentially applied Carr’s blueprint.

C. Res judicata and “fully and fairly litigated” jurisdiction

  • Underwriters Nat'l Assurance Co. v. N.C. Life & Accident & Health Ins. Guar. Ass'n — Provided the controlling limitation: res judicata can preclude relitigation of jurisdiction only if the issue was “fully and fairly litigated” in the rendering court.
  • Genuine Parts Co. v. Rascal's Auto Parts, Inc. — Illustrated when the “fully and fairly litigated” threshold is met (i.e., the party actually raised personal jurisdiction in the rendering court), thereby barring a collateral attack. The Court used Genuine Parts as a contrast: CRP never had a genuine opportunity to litigate jurisdiction because Gerald’s purported consent was unauthorized.
  • In re Child Support of Mason — Reinforced that extensive briefing and identical argument in the rendering court can bar relitigation. Again, the Court contrasted Mason with this case’s absence of jurisdiction litigation in Idaho.

D. Idaho law on personal jurisdiction via voluntary appearance

  • Telford v. Smith County — Supplied the Idaho-law proposition that a voluntary general appearance waives personal jurisdiction objections. The Montana Supreme Court accepted this framework but held CRP never validly “appeared” because Gerald lacked authority to do so for CRP.

E. Partnership authority: “ordinary course,” apparent authority, and authorization/ratification

  • Rock Island Plow Co. v. Cut Bank Implement Co. and New Hope Lutheran Ministry v. Faith Lutheran Church of Great Falls, Inc. (noting partial overruling in Warrington v. Great Falls Clinic, LLP) — Used to cabin the evidentiary presumption in § 26-1-602(20), MCA: a presumption that “ordinary course of business has been followed” does not define what the ordinary course is, nor does it establish that a challenged act fits within it.
  • Baltrusch v. Baltrusch and Rodgers v. Saunders — Provided practical examples distinguishing acts within and outside a partnership’s ordinary course. The Court relied on these analogies to characterize Gerald’s Idaho probate maneuvering and confession of judgment as outside CRP’s ordinary agricultural-leasing business.
  • Schrammeck v. Fed. Sav. & Loan Ins. Corp. — Helped frame the inquiry into whether documents purported to bind the partnership and how partner authority is assessed under § 35-10-301, MCA. The Court used similar reasoning to discount Gerald’s promissory notes (they did not reference CRP or a representative capacity).
  • Est. of Pruyn v. Axmen Propane, Inc. (noting partial overruling in Associated Mgmt. Servs., Inc. v. Ruff) — Supported the proposition that apparent authority is not established where the instrument does not identify the principal or representative capacity; this helped the Court reject the Estate’s attempt to attribute Gerald’s promissory notes to CRP.
  • Associated Mgmt. Servs., Inc. v. Ruff, Scott D. Erler, D.D.S. Profit Sharing Plan v. Creative Fin. & Invs., L.L.C., and Safeco Ins. Co. v. Lovely Agency — Supplied Montana’s modern ratification doctrine: ratification requires acceptance of benefits, full knowledge, and circumstances indicating intent to adopt the unauthorized act; mere acquiescence is not necessarily enough. This triad was central to rejecting the Estate’s “Linda ratified Gerald” theory.

F. Timeliness: “reasonable time” and prejudice

  • In re Marriage of Waters — Provided the Montana lens for “reasonable time” and emphasized prejudice (or lack thereof) as a key factor. The Court invoked Waters to support a finding of reasonableness despite extended delay where the opposing party is not harmed.
  • United States v. Holtzman — Provided persuasive federal guidance considering prejudice and reasons for delay; the Court analogized CRP’s situation to delayed discovery/understanding and lack of harm to the opposing party.
  • Bahm v. Southworth — Served as a limiting contrast: delay can be unreasonable when the movant had early knowledge and other timely Rule 60 avenues were available. The Court distinguished CRP’s case because Linda testified she did not know of the judgment until enforcement in 2024.
  • In re Wilson and Fischer v. Barnett Bank of S. Fla. — Cited by the Estate to argue neglect in monitoring mail, but the Court distinguished them on their facts: those parties had stronger reason to anticipate litigation mail or had initiated proceedings, unlike Linda, who had not been served and had no reason to expect a confessed judgment against CRP.
  • Est. of Harris v. Reilly — Reaffirmed the Court’s insistence that parties must develop arguments and provide legal support; it was used to reject the Estate’s effort to impute Gerald’s knowledge to Linda/CRP without authority or legal grounding.

3.2 Legal Reasoning

A. The Court’s sequencing: full faith and credit → permissible collateral attack → jurisdiction analysis

The Opinion follows a disciplined sequence. It begins with the constitutional premise—full faith and credit—then immediately invokes the established exception: Montana may examine the rendering court’s personal jurisdiction when a foreign judgment is domesticated (via UEFJA and Rule 60). This is doctrinally important because it frames the analysis as a validity inquiry rather than an impermissible “appeal” from Idaho.

B. Res judicata did not bar the challenge because Idaho never “fully and fairly” decided jurisdiction over CRP

The Estate’s res judicata argument depended on treating Gerald’s stipulation as if it were CRP’s genuine litigation position. The Court rejected that premise: if Gerald lacked authority to act for CRP, then CRP never truly appeared, never truly waived, and never had a meaningful chance to litigate. Because the Idaho court entered judgment on the stipulation without briefing or findings about CRP-specific jurisdiction and partner authority, the issue was not “fully and fairly litigated” under Underwriters Nat'l Assurance Co. v. N.C. Life & Accident & Health Ins. Guar. Ass'n.

C. Partner authority turned on “ordinary course” versus “authorized by other partners” under § 35-10-301, MCA

The heart of the case is the Court’s choice of the controlling statutory prong:

  • If Gerald was “apparently carrying on in the ordinary course of the partnership business,” § 35-10-301(1), MCA might bind CRP unless the third party knew of limits.
  • If he was not, then § 35-10-301(2), MCA applies: he could bind CRP only if the act was authorized by the other partners.

The Court concluded Gerald’s conduct—participation in Idaho probate restraint proceedings and later confessing a seven-figure judgment against a Montana agricultural partnership for misappropriations committed in Idaho—was not within CRP’s ordinary course (leasing and managing Montana farmland). Therefore, § 35-10-301(2), MCA controlled, and authorization (including ratification) was required.

D. No authorization; no ratification

The Court found no evidence that Linda, the managing partner, authorized Gerald to: (1) appear for CRP; (2) consent to Idaho jurisdiction for CRP; or (3) confess CRP’s liability. On ratification, the Court applied the Associated Mgmt. Servs., Inc. v. Ruff / Scott D. Erler, D.D.S. Profit Sharing Plan v. Creative Fin. & Invs., L.L.C. framework and held the Estate failed on the crucial elements of full knowledge and intent to adopt. Courtesy emails in March 2020 about a temporary restraint were not knowledge of (and could not retroactively approve) an August 2020 confession of judgment.

E. Idaho long-arm not satisfied as to CRP

With “consent jurisdiction” off the table, Idaho’s long-arm statute controlled. The Court held the record demonstrated CRP did not transact business in Idaho and did not commit tortious acts there. Accordingly, Idaho Code § 5-514(a), (b) (2020) did not extend jurisdiction over CRP.

F. Timeliness: four years can still be “reasonable” for Rule 60(b)(4) where there is no prejudice and a credible explanation

The Court treated “reasonable time” as a context-specific inquiry (drawing from In re Marriage of Waters and United States v. Holtzman): it weighed (1) prejudice to the Estate and (2) CRP’s reason for delay. The Estate showed no enforcement efforts until late 2024 and no detrimental reliance. Linda testified credibly that she did not learn of the Idaho judgment until execution efforts began and explained why she did not open accumulated mail in 2020. The Court held CRP acted promptly once the judgment was actually pressed against it.

3.3 Impact

A. For judgment creditors seeking to bind partnerships

The decision is a cautionary precedent: creditors cannot safely rely on a single partner’s signature to obtain a binding confession of judgment against a partnership, especially where the partnership agreement restricts authority and the act is outside ordinary operations. Creditors who want enforceable judgments should: (1) ensure proper service and appearance by an authorized agent; (2) verify authority under the partnership agreement; and (3) obtain express consent/ratification from the managing partner(s) when acts are extraordinary (e.g., confessions of liability, submission to foreign jurisdiction).

B. For Montana partnerships (and their governance documents)

Estate of Pfeifer-Murphy gives real litigation force to governance allocations in partnership agreements under § 35-10-106(1), MCA. When a partnership agreement centralizes management authority, courts may treat extra-ordinary litigation decisions—such as confessing judgment or consenting to foreign jurisdiction— as requiring explicit authorization.

C. For domesticated judgments and Rule 60(b)(4) practice

The Opinion reinforces that domestication does not immunize a foreign judgment from jurisdictional scrutiny in Montana. It also signals that “reasonable time” under Rule 60(c)(1) is not a mechanical clock, especially for voidness challenges where enforcement begins years later. Practically, parties seeking to enforce old domesticated judgments should expect courts to examine (and require proof of) jurisdictional validity if the debtor plausibly lacked notice and did not truly appear.

D. For probate-related litigation strategies

Probate proceedings often involve emergency restraints and negotiated resolutions. This decision warns that expanding a settlement to include an out-of-state entity (like a partnership holding valuable land) requires careful attention to personal jurisdiction and to who may bind that entity. “Global” settlements can fracture at enforcement if authority and jurisdiction are assumed rather than established.

4. Complex Concepts Simplified

  • Domesticated foreign judgment: A judgment from State A filed in State B for enforcement. Under the UEFJA, it is treated like a local judgment for enforcement, but can still be attacked as invalid (e.g., for lack of personal jurisdiction).
  • Personal jurisdiction: A court’s power to bind a specific defendant. It can come from sufficient contacts under a long-arm statute or from a valid voluntary appearance/waiver.
  • Rule 60(b)(4) “void” judgment: A judgment is void if the court lacked jurisdiction (not merely mistaken). If void, the judgment cannot stand.
  • Res judicata: A doctrine preventing relitigation of issues already decided. For jurisdiction issues, it applies only if the jurisdiction question was “fully and fairly litigated.”
  • Ordinary course of partnership business: The routine activities that match the partnership’s purpose and usual operations. Extraordinary acts (like confessing judgment) typically fall outside this scope.
  • Apparent authority vs. actual authority: Apparent authority depends on what a third party reasonably believes from the principal’s manifestations; actual authority comes from real permission given by the partnership/other partners.
  • Ratification: Later approval of an unauthorized act, requiring knowledge of material facts and conduct showing an intent to adopt the act (often by accepting benefits).
  • Deemed denial: A motion is automatically denied by operation of rule if the court does not decide it within a prescribed time.

5. Conclusion

Estate of Pfeifer-Murphy establishes a clear guardrail for cross-border enforcement: a foreign judgment against a Montana partnership is void and must be vacated under Rule 60(b)(4) where the rendering court lacked personal jurisdiction, and that defect cannot be cured by an unauthorized partner’s stipulation or confession of judgment. The decision also meaningfully limits res judicata in the jurisdiction setting by insisting on a genuinely “fully and fairly litigated” opportunity and clarifies that “reasonable time” to seek voidness relief may extend for years when enforcement is delayed and prejudice is absent.

The broader significance is institutional: the Court preserves the integrity of partnership governance allocations, reinforces jurisdictional due process in the domestication context, and signals to litigants that enforceability depends not only on having a judgment, but on having a judgment entered against the right party through lawful jurisdictional means.
