Montana Insurance Claims Handling & Bad Faith

Montana closely regulates how insurers investigate, evaluate, communicate, decide coverage and settle claims. “Bad faith” remains useful public shorthand, but current Montana law requires the legal analysis to identify the specific statutory violation, contract claim or fraud theory actually authorized.

Current-law review: Sept. 12, 2026 Primary remedy: MCA § 33-18-242 Reasonable investigation matters

“Bad faith” is shorthand—not the current cause-of-action label

Montana's Legislature now expressly identifies which claim-handling legal theories an insured or third-party claimant may pursue against an insurer.

Insured

Current authorized theories

Under MCA § 33-18-242, an insured who suffers damages from handling of an insurance claim may pursue breach of the insurance contract, fraud, or the independent statutory action provided by § 33-18-242.

Third-party claimant

Current authorized theories

A third-party claimant who suffers damages from claim handling may pursue fraud or the independent statutory action under § 33-18-242, subject to its procedural requirements.

Current § 33-18-242 expressly bars a separate bad-faith cause of action arising from claim handling. Older Montana opinions using common-law bad-faith terminology remain historically important, but the present statute controls identification of today's causes of action.

Montana's core insurer claim-handling duties

MCA § 33-18-201 lists numerous prohibited claim practices. Six of those subsections currently support the independent private action created by § 33-18-242.

§ 33-18-201(1)

Truthful coverage information

An insurer may not misrepresent pertinent facts or insurance-policy provisions relating to coverages at issue.

§ 33-18-201(4)

Reasonable investigation

An insurer may not refuse payment without conducting a reasonable investigation based on all available information.

§ 33-18-201(5)

Timely coverage decision

An insurer may not fail to affirm or deny coverage within a reasonable time after proof-of-loss statements have been completed.

§ 33-18-201(6)

Prompt, fair and equitable settlement

When liability has become reasonably clear, the insurer must make good-faith efforts toward prompt, fair and equitable settlement.

§ 33-18-201(9)

No altered-application settlement

The insurer may not attempt to settle a claim based on an application altered without proper notice to or knowledge or consent of the insured.

§ 33-18-201(13)

No improper coverage leverage

When liability is reasonably clear, one portion of coverage may not be withheld in order to influence settlement under another portion.

Not every § 33-18-201 prohibition creates the same private remedy. Requirements such as subsection (14)'s reasonable explanation for a denial remain statutory claim-handling duties, but subsection (14) is not presently one of the six provisions independently actionable under § 33-18-242.

How the current statutory action works

Issue Current Montana rule
Actionable UTPA provisions § 33-18-201(1), (4), (5), (6), (9), and (13).
General business practice A plaintiff under § 33-18-242 does not have to prove violations occurred frequently enough to establish a general business practice.
Insured's theories Breach of insurance contract, fraud, or § 33-18-242 statutory action.
Third-party claimant's theories Fraud or § 33-18-242 statutory action.
Separate bad-faith action Not authorized in connection with handling the insurance claim under current § 33-18-242.
Damages Damages proximately caused by an actionable statutory violation.
Insurer defense No liability under § 33-18-242 if the insurer had a reasonable basis in law or fact for contesting the claim or amount at issue.

Who can file—and when?

Insured

May file with other claims

An insured may bring the § 33-18-242 action together with other causes of action the insured is authorized to assert against the insurer, subject to possible bifurcation where justice requires.

Third-party claimant

Statutory action generally comes later

A third-party claimant may not file the § 33-18-242 action until the underlying liability claim has settled or judgment has been entered in favor of the claimant.

Current limitation periods

Plaintiff § 33-18-242 limitations period
Insured Generally within two years from the date of the § 33-18-201 violation.
Third-party claimant Generally within one year from settlement of the underlying claim or entry of judgment.
Document the conduct while the underlying claim is still active. A third-party statutory action may not yet be fileable, but claim-handling evidence can disappear or become difficult to reconstruct later.

The insurer has a statutory reasonable-basis defense

Montana does not impose statutory liability merely because the insurer eventually loses a coverage, causation or valuation dispute.

Section 33-18-242 provides that an insurer may not be held liable under that section if it had a reasonable basis in law or fact for contesting the claim or the amount of the claim.

A genuinely debatable claim may be contested. The UTPA does not require automatic payment whenever a demand is made. The issue is whether the position taken had a reasonable legal or factual basis when the claim was actually being handled.

Dean: factual reasonableness often belongs to the fact finder

Dean v. Austin Mutual Insurance Co., 263 Mont. 386, 869 P.2d 256 (1994), explains that where the insurer's reasonableness depends on disputed evidence and credibility, the question ordinarily belongs to the trier of fact.

That is not an absolute rule. Later Montana cases recognize circumstances in which reasonable basis can be resolved as a matter of law, particularly when the question turns only on the legal landscape and no material factual dispute remains.

The legal landscape is measured when the claim was adjusted

Montana's reasonable-basis analysis looks to the law and information available during the relevant claim-handling period—not merely to a legal argument developed after litigation begins.

Timing matters. Reconstruct what the adjuster and insurer knew, what authority existed, what investigation had been completed, and what factual basis supported the position at the time the decision was made.

A later payment does not automatically cure an earlier unreasonable investigation

McVey v. USAA Casualty Insurance Co., 2013 MT 346, is particularly important for automobile claims.

USAA eventually paid McVey the available UM/UIM limits after further investigation. The Montana Supreme Court held that eventual payment was not enough, by itself, to preclude scrutiny under § 33-18-201(4) of whether the insurer's earlier investigation had been reasonable.

Ultimate payment does not necessarily erase earlier claim handling. The investigation can be evaluated as a separate statutory issue.

The operative question remains whether the insurer actually conducted the reasonable investigation Montana law required before taking the disputed claim position.

Ridley: reasonably clear liability can require payment before global settlement

Ridley v. Guaranty National Insurance Co., 286 Mont. 325, 951 P.2d 987 (1997), remains one of Montana's most significant automobile claim-handling decisions.

Under the circumstances addressed there, the UTPA did not permit the liability insurer simply to withhold qualifying medical expenses until the injured third-party claimant agreed to settle every component of the case.

Ridley is not an automatic-payment rule for every medical bill. Causation, necessity, reasonableness, amount, comparative fault and other genuine factual disputes can remain. The question is whether liability for the particular component has become reasonably clear.

Shilhanek: Ridley is not confined to compulsory minimum limits

In Shilhanek v. D-2 Trucking, Inc., 2003 MT 122, 315 Mont. 519, 70 P.3d 721, the Montana Supreme Court rejected an argument that Ridley's UTPA analysis applied only within Montana's compulsory minimum automobile-liability limits.

The Court explained that Ridley arises from Montana's UTPA rather than only from the motor-vehicle financial-responsibility statute.

Watters: mandatory limits cannot always be held for a global release

Watters v. Guaranty National Insurance Co., 2000 MT 150, 300 Mont. 91, 3 P.3d 626, involved reasonably clear automobile liability and damages that undisputedly exceeded the applicable mandatory limits.

Under those circumstances, the Montana Supreme Court held that conditioning payment of the owed mandatory limits on a full and final release constituted an unfair trade practice.

Watters should not be converted into a universal rule governing every excess limit or every settlement dispute. Its holding expressly addressed the mandatory automobile limits and facts before the Court.

Watters also demonstrates the reasonable-basis defense

Although the Court announced the substantive rule, it concluded that the insurer had relied on then-existing Montana precedent that provided a reasonable basis in law for its earlier position.

The case therefore demonstrates both sides of Montana's statutory system: a substantive insurer duty and a distinct reasonable-basis defense.

The claimant's cooperation now matters expressly

MCA § 33-18-243, enacted in 2023, expressly requires insureds and third-party claimants to cooperate with an insurer concerning an insurance claim and comply with reasonable requests in the investigation and handling of the claim.

They also must deliver reasonably available claim information sufficient to provide the insurer a fair and reasonable opportunity to investigate and evaluate the claim.

Insurer

Reasonably investigate

Seek and evaluate material liability, coverage and damage information before refusing payment or taking a claim position.

Insured / claimant

Provide reasonably available information

Cooperate with reasonable requests and provide information sufficient to create a fair investigative opportunity.

A claimant's breach does not create a separate insurer damages action under § 33-18-243. But it can be considered as evidence and may support an affirmative defense to specified § 33-18-242 claims concerning investigation, coverage timing or reasonably clear settlement.

Claims-handling audit

Reconstruct the claim chronologically. The central question is what the insurer knew, what it did with that information, and whether its position remained reasonable as the record developed.

Identify every applicable coverage. Determine which insurer, policy, insured and coverage part is responding.
Build the information timeline. Record when each important liability, coverage and damages fact reached the insurer.
Examine the investigation. Determine what evidence the insurer sought, what it possessed and what it failed to investigate.
Separate each disputed component. Liability for causing the crash, medical causation, treatment necessity, property loss and future damages may become reasonably clear at different times.
Identify every stated reason for the insurer's position. Separate legal basis, factual basis, coverage dispute and valuation dispute.
Test whether that basis was reasonable when asserted. Compare the stated justification with the information and law actually available during the claim-handling period.
Identify what changed over time. A position that was reasonable at one stage may require reassessment when new medical, liability, coverage or legal information arrives.
Evaluate insured or claimant cooperation. Determine what information was reasonably requested, what was supplied, what was unavailable and whether any omission materially affected the investigation.
Identify any coverage leverage. Determine whether one portion of coverage was delayed or withheld to influence settlement of another.
Identify the damages caused by the alleged statutory violation. Section 33-18-242 requires proximate causation between the actionable violation and the damages sought.

  • settlement offers

  • excess-exposure communications

Damages require causation

Section 33-18-242 authorizes recovery of damages proximately caused by an actionable violation of § 33-18-201.

A statutory violation and damages are separate elements. Identify what loss resulted from the particular actionable conduct rather than assuming that every claim-handling error automatically produces the full value of the underlying insurance claim as statutory damages.

Punitive damages require a separate showing

Section 33-18-242 allows exemplary damages only in accordance with Montana's punitive-damages law. A UTPA violation does not automatically establish entitlement to punitive damages.

Punitive damages require the separate proof demanded by MCA § 27-1-221, including actual fraud or actual malice under the statutory standard.

Estate of Gleason: UTPA damages and punitive damages are distinct questions

Estate of Gleason v. Central United Life Insurance Co., 2015 MT 140, illustrates why contract benefits, statutory claim-handling damages and punitive-damages proof should not be collapsed into one inquiry.

First-party and third-party claims require different records

First-party claim

The insured versus the insured's own carrier

Track the contractual benefit, the claim investigation, the insurer's stated basis, any breach of contract, any independently actionable UTPA violation, any supported fraud theory and damages attributable to each alleged wrong.

Third-party claim

The injured claimant versus the liability insurer

Track when liability became reasonably clear, which damages became reasonably clear, what information was supplied, what remained disputed, settlement conduct, any release demand and the ultimate settlement or judgment.

“Reasonably clear liability” is not synonymous with maximum possible damages. Montana's statute protects fair treatment of amounts that have become reasonably clear while preserving legitimate disputes over causation, comparative fault, necessity of treatment and amount of damages.

Common claims-handling mistakes

  • Calling every insurance dispute “bad faith” without identifying the legal claim.
  • Using an older common-law case without checking current § 33-18-242.
  • Assuming every § 33-18-201 subsection creates a private action.
  • Failing to distinguish contract damages from UTPA damages.
  • Assuming denial automatically establishes unreasonable conduct.
  • Assuming ultimate payment automatically cures an earlier inadequate investigation.
  • Treating liability for the crash as proof that every damage item is reasonably clear.
  • Ignoring the insurer's reasonable-basis defense.
  • Judging the insurer only with information learned after the claim decision.
  • Failing to document when important evidence reached the carrier.
  • Ignoring claimant cooperation under § 33-18-243.
  • Ignoring which requested information was reasonably available.
  • Failing to preserve settlement demands and responses.
  • Conditioning analysis solely on whether policy limits were eventually paid.
  • Assuming a UTPA violation automatically establishes punitive damages.

Montana authority map

Primary Law · MCA § 33-18-201 Unfair claim settlement practices

Montana's principal claim-practices statute. It regulates misrepresentation, communications, investigation, coverage decisions, settlement conduct and other insurer practices.

Primary Law · MCA § 33-18-242 Independent statutory cause of action

Authorizes actual damages caused by violations of § 33-18-201(1), (4), (5), (6), (9), or (13); identifies available legal theories; creates the reasonable-basis defense; establishes third-party filing timing and limitations periods; and permits exemplary damages only under Montana's punitive-damages statute.

Primary Law · MCA § 33-18-243 Insured and claimant cooperation duties

Requires cooperation with reasonable investigative requests and delivery of reasonably available claim information, while allowing qualifying breaches to be used as evidence and specified affirmative defenses.

Montana Supreme Court Klaudt v. Flink, 202 Mont. 247, 658 P.2d 1065 (1983)

Historically foundational third-party UTPA authority. It predates Montana's current express statutory cause-of-action framework and should be read as part of the doctrine's development.

Montana Supreme Court Dean v. Austin Mutual Insurance Co., 263 Mont. 386, 869 P.2d 256 (1994)

Important reasonable-basis authority recognizing that reasonableness depending on disputed evidence and witness credibility commonly presents a fact question.

Montana Supreme Court Ridley v. Guaranty National Insurance Co., 286 Mont. 325, 951 P.2d 987 (1997)

Landmark reasonably-clear-liability decision recognizing that qualifying medical expenses may become payable before final settlement of an entire third-party bodily-injury claim.

Montana Supreme Court Watters v. Guaranty National Insurance Co., 2000 MT 150, 300 Mont. 91, 3 P.3d 626

Holds that under its mandatory-limit facts, owed minimum automobile liability limits could not be conditioned on a complete release once liability was reasonably clear and damages undisputedly exceeded those limits. Also illustrates the reasonable-basis defense.

Montana Supreme Court Shilhanek v. D-2 Trucking, Inc., 2003 MT 122, 315 Mont. 519, 70 P.3d 721

Confirms that Ridley's UTPA rule is not confined to Montana's compulsory minimum automobile limits, while separately applying the reasonable-basis defense to the insurer's earlier settlement position.

Montana Supreme Court Lorang v. Fortis Insurance Co., 2008 MT 252, 345 Mont. 12, 192 P.3d 186

Important claims-handling and damages authority. Later Montana cases rely on Lorang for the principle that subsequent payment does not necessarily cure an earlier failure to investigate reasonably.

Montana Supreme Court McVey v. USAA Casualty Insurance Co., 2013 MT 346

Auto-insurance investigation authority holding that eventual payment of UM/UIM benefits did not automatically shield the carrier from a § 33-18-201(4) claim based on the adequacy of its earlier investigation.

Montana Supreme Court Estate of Gleason v. Central United Life Insurance Co., 2015 MT 140

Modern authority emphasizing that the insurer's conduct and reasonable basis must be evaluated against the law and information available when the underlying claim was being adjusted; also addresses the relationship among contract recovery, UTPA findings and punitive damages.

Source-control rule: current Montana statutes and official Montana Supreme Court opinions control. Older decisions using broad common-law bad-faith terminology should not be assumed to state the causes of action presently authorized by MCA § 33-18-242.

Frequently asked questions

Can I sue a Montana insurer for “bad faith”?

“Bad faith” remains useful public terminology, but current MCA § 33-18-242 expressly limits claim-handling theories. An insured may pursue breach of contract, fraud, or the statutory action; a third-party claimant may pursue fraud or the statutory action. The statute bars a separate bad-faith claim arising from handling the insurance claim.

Which UTPA violations can support the statutory action?

Current § 33-18-242 identifies § 33-18-201(1), (4), (5), (6), (9), and (13).

Does the plaintiff have to prove that the insurer routinely does this to many people?

No. Section 33-18-242 expressly states that a plaintiff in the independent statutory action does not have to prove violations occurred frequently enough to establish a general business practice.

Can an insurer contest a disputed claim without violating the UTPA?

Yes. Section 33-18-242 provides a defense when the insurer had a reasonable basis in law or fact for contesting the claim or amount at issue.

If the insurer eventually pays, does that end an unreasonable-investigation claim?

Not automatically. McVey holds that later payment does not itself cure or erase an earlier failure to conduct the reasonable investigation required by § 33-18-201(4).

Does Ridley require immediate payment of every medical bill?

No. Ridley applies when liability for the particular expense has become reasonably clear. Causation, reasonableness, necessity, amount and other legitimate disputes can remain.

Can a third-party claimant file the UTPA suit while the injury case is still pending?

The § 33-18-242 damages action generally cannot be filed until the underlying claim is settled or judgment has been entered in the claimant's favor. The conduct should nevertheless be documented as it occurs.

How long does an insured have to file a § 33-18-242 action?

The statute presently provides two years from the date of the § 33-18-201 violation for an insured's statutory action.

How long does a third-party claimant have?

The current statute generally provides one year from settlement of the underlying claim or entry of judgment.

Does a claimant have to cooperate with the insurer?

Yes. MCA § 33-18-243 imposes express cooperation and claim-information duties. Failure to comply does not create an insurer's independent damages action, but it can affect evidence and specified statutory defenses.

Does proving a UTPA violation automatically produce punitive damages?

No. Exemplary damages require the separate showing required by Montana's punitive-damages statute.

A claims-handling case is built from the timeline.

Identify what coverage applied. Reconstruct what the insurer knew and when. Examine the investigation. Determine when liability or particular damages became reasonably clear. Identify the carrier's contemporaneous legal or factual basis. Evaluate claimant cooperation. Then connect any actionable statutory violation to the damages it actually caused.

Public legal education only. This page does not create an attorney-client relationship and is not individualized legal advice. Montana insurance claim-handling law depends on the current statutory text, the complete policy, claim chronology, information available to the insurer, claimant cooperation, the legal and factual basis for disputed positions, causation and resulting damages. Montana's statutes governing available causes of action changed materially in 2023. Older decisions describing common-law “bad faith” should not be assumed to identify the legal theories currently permitted by MCA § 33-18-242. Verify current statutes, complete official opinions and current treatment before legal reliance.
