Montana Coverage Disclosure & Insurer Duties

Montana imposes substantial duties concerning truthful coverage representations, investigation, coverage decisions and settlement. Those duties do not create one universal rule requiring every liability insurer to produce every adverse insured's complete policy and limits before litigation. The source of the asserted duty and the procedural stage must be identified precisely.

Current-law review: Sept. 12, 2026 Request ≠ statutory right Pre-suit ≠ formal discovery

Separate three different legal questions

Coverage transparency is not one legal issue. A useful Montana analysis separates accuracy, claim handling, and production of the insurance contract.

Question one

Must the insurer tell the truth about coverage?

Yes. MCA § 33-18-201(1) prohibits misrepresentation of pertinent facts or policy provisions relating to coverages at issue.

Question two

Must the insurer investigate and take a coverage position?

Montana regulates claim investigation, timing of coverage decisions, reasonably clear liability, payment practices and explanations of claim positions.

Question three

Must the insurer produce the complete policy and limits?

That depends on who is requesting the information, the relationship to the policy, whether a specialized statute applies, and whether formal litigation discovery has begun.

Procedural stage

Before suit and after suit are different

An informal third-party pre-suit request does not operate under the same legal mechanism as Rule 26 insurance discovery after litigation begins.

A request for policy information is not the same thing as a statutory right to obtain it. A written request can still be useful and important, but the legal basis for compelling production should not be overstated.

An insured's own policy stands on a different footing

MCA § 33-15-412 requires an issued insurance policy, subject to the statute's conditions, to be mailed or delivered to the insured or other person entitled to receive it within a reasonable period after issuance.

That insured-policy relationship is materially different from a third-party claimant asking an adverse liability insurer to disclose another person's policy before suit.

If you are investigating your own coverage: request the complete policy, declarations, endorsements, renewal documents, coverage-selection materials, UM rejection records where relevant, and any other policy forms applicable to the date of loss.

Montana's UTPA regulates the integrity of claim handling

MCA § 33-18-201 identifies numerous unfair claim settlement practices. Several are directly relevant to coverage information and claim evaluation.

§ 33-18-201(1)

Coverage misrepresentation

An insurer may not misrepresent pertinent facts or 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)

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)

Reasonably clear liability

An insurer may not neglect good-faith efforts toward prompt, fair and equitable settlement when liability has become reasonably clear.

§ 33-18-201(10)

Identify certain claim payments

Certain payments to insureds or beneficiaries must be accompanied by a statement identifying the coverage under which the payment is made.

§ 33-18-201(14)

Explain denial or compromise

Montana requires a reasonable explanation of the policy basis in relation to the facts or applicable law for denial of a claim or an offer of compromise settlement.

Coverage information that is actually communicated must be accurate. The absence of a universal pre-suit policy-production rule does not permit an insurer to affirmatively misrepresent the coverage at issue.

Not every UTPA prohibition has the same private remedy

MCA § 33-18-242 creates an independent statutory action for insureds and third-party claimants, but only for specified subsections of § 33-18-201.

§ 33-18-201 provision Independent § 33-18-242 action? Subject
(1) Yes Misrepresentation of pertinent facts or policy provisions.
(4) Yes Refusal without reasonable investigation.
(5) Yes Failure to timely affirm or deny coverage.
(6) Yes Failure to attempt prompt, fair and equitable settlement when liability is reasonably clear.
(9) Yes Attempting settlement based on an application altered without notice, knowledge or consent of the insured.
(13) Yes Delaying one portion of coverage to influence settlement under another portion.
(10) No independent § 33-18-242 claim Identification of coverage for certain claim payments.
(14) No independent § 33-18-242 claim Explanation of denial or compromise settlement.
Do not convert the entire UTPA into one private cause of action. Section 33-18-201 contains more prohibited practices than the six subsections currently identified in § 33-18-242(1).

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

The statute further specifies the procedural timing of a third-party claimant's action: the underlying claim must first be settled or judgment entered in the claimant's favor. The current limitations period for that third-party statutory action is generally one year from settlement or entry of judgment.

Pre-suit third-party policy disclosure requires careful wording

A third-party claimant can and often should make a focused written request for available liability insurance information. The request creates a record, may produce voluntary disclosure, and can identify disputed coverage issues.

But the request should not be described as invoking a universal Montana statute requiring every liability carrier to turn over the complete policy or limits merely because the claimant asks.

Publication-safe rule: request the information, preserve the response, identify any affirmative representation, and continue the independent coverage investigation—but do not represent Montana as presently having a universal pre-suit third-party policy-limit disclosure statute.

Bateman: misrepresentation is not the same thing as nondisclosure

In Bateman v. National Union Fire Insurance Co. of Pittsburgh, Pa., 423 F. App'x 763 (9th Cir. 2011), a nonprecedential federal appellate decision applying Montana law, the Ninth Circuit rejected an asserted § 33-18-201(1) disclosure theory where the claimants did not allege an affirmative misrepresentation.

The court explained that the misrepresentation subsection did not itself impose the asserted duty to disclose an explanation of coverage, policy limits and defense expenditures merely because third-party claimants requested them.

Bateman is federal authority applying Montana law. It is important persuasive authority, but it is not a Montana Supreme Court opinion.

Amberg: the District of Montana followed Bateman in 2025

In Amberg v. Travelers Casualty & Surety Co. of America, No. 2:24-cv-00070-DLC (D. Mont. July 1, 2025), the federal court again distinguished an affirmative misrepresentation from an asserted failure to volunteer policy information.

Applying Bateman, the court rejected the theory that § 33-18-201(1) itself imposed the claimed generalized disclosure duty.

Amberg is persuasive, not controlling Montana Supreme Court authority. It nevertheless provides an important current federal application of Montana's UTPA disclosure law.

Wilkie did not decide the substantive disclosure question

In Wilkie v. Hartford Underwriters Insurance Co., 2021 MT 221, 405 Mont. 259, 494 P.3d 892, Paul Wilkie was injured when Hartford's insured struck him with a truck. Hartford concluded that its insured's liability was reasonably clear and began making Ridley medical payments.

Wilkie's counsel requested the policy or, alternatively, the applicable liability limit. Hartford declined to provide it, and Wilkie filed a declaratory action seeking a ruling that Montana law required disclosure before litigation.

The insureds later produced the policy. The District Court dismissed the disclosure action as moot.

The Montana Supreme Court reversed because the voluntary-cessation exception to mootness had not been properly applied.

The Supreme Court expressly did not reach the merits. Wilkie should not be cited as holding that every Montana liability insurer must disclose every liability policy or policy limit to every third-party claimant before suit.

After litigation begins, insurance becomes a formal discovery subject

Montana Rule of Civil Procedure 26(b)(5) permits discovery of the existence and contents of an insurance agreement under which an insurer may be liable to satisfy all or part of a judgment or to indemnify or reimburse payments made to satisfy that judgment.

This is a formal legal mechanism different from an informal pre-suit request. Once litigation begins, qualifying insurance agreements are expressly discoverable under the Montana Rules of Civil Procedure.

The Rule also provides that insurance information is not made admissible at trial merely because it is discoverable.

Discovery and admissibility are separate questions. Information can be important and discoverable for litigation and settlement planning without itself becoming trial evidence.

Coverage duties and payment duties can arise before final settlement

Ridley: qualifying medical expenses may require advance payment

Ridley v. Guaranty National Insurance Co., 286 Mont. 325, 951 P.2d 987 (1997), is an important Montana authority construing § 33-18-201(6) and (13).

Under the circumstances addressed by the decision, when liability was reasonably clear, the carrier could not simply withhold qualifying medical expense payments until the claimant accepted a global final settlement.

“Liability reasonably clear” is issue-specific. Responsibility for causing the crash does not automatically establish that every medical treatment, charge, causation question or damage component is reasonably clear.

Watters: mandatory limits and a demanded global release

Watters v. Guaranty National Insurance Co., 2000 MT 150, 300 Mont. 91, 3 P.3d 626, extended the Montana analysis in the particular circumstances before the Court.

Where liability was reasonably clear and damages undisputedly exceeded the mandatory minimum automobile-liability limits, the insurer could not condition payment of those owed mandatory limits on a full and final release of all liability.

Do not generalize Watters beyond its holding. The decision expressly involved Montana's mandatory automobile-liability protection and its particular facts.

Current Montana law also imposes duties on insureds and claimants

MCA § 33-18-243, enacted in 2023, expressly requires an insured or third-party claimant to cooperate with the insurer concerning the claim and to comply with reasonable requests during investigation and handling.

The statute also requires delivery of claim information sufficient to give the insurer a fair and reasonable opportunity to investigate and evaluate each claim.

Cooperation

Reasonable investigative requests

Claimants and insureds must cooperate with reasonable requests connected to investigation and handling of the claim.

Claim information

Provide reasonably available evidence

The statutory definition includes reasonably available information relating to damages and liability.

A breach does not create a separate insurer cause of action under § 33-18-243. But the conduct may be evidence concerning the insurer's investigative opportunity and reasonable-basis defense, and can operate as an affirmative defense to specified claims.

Time-limited settlement demands have their own information rules

MCA § 33-18-251 creates a detailed procedure for a claimant who wants a settlement demand to qualify as a statutory time-limited demand.

Among other requirements, the demand must:

  • reference § 33-18-251
  • be in writing
  • be labeled “time sensitive” at the top of the first page
  • be sent by certified mail, return receipt requested
  • identify the allegedly responsible party
  • remain open at least 60 days
  • state the settlement amount and other consideration requested
  • identify the occurrence
  • describe known injuries, damages and losses
  • identify parties to be released
  • identify claims to be released
  • provide required Medicare, Medicaid, lien and assignment information
  • include supporting records sufficient for fair investigation
An artificially short deadline is not a substitute for statutory compliance. Section 33-18-251 expressly regulates the timing, content, delivery and supporting documentation for a qualifying time-limited demand.

The statute also allows the insurer to request clarification, additional information or proposed settlement/release language without that request automatically constituting a rejection or counteroffer. Such a request can extend the response period under the statutory formula.

A demand that does not strictly comply may not be treated as the statutory reasonable settlement opportunity supporting the extracontractual consequences described in § 33-18-251.

Rideshare claims have a specialized information-exchange rule

MCA § 69-12-345 creates more specific duties during a TNC claims coverage investigation.

Transportation network carriers and insurers potentially providing liability or optional coverage must cooperate to exchange relevant information with directly involved parties and applicable insurers.

Montana expressly reaches the digital timeline. The information exchange includes the precise times the driver logged on and off the TNC digital network during the 12 hours immediately before and the 12 hours immediately after the crash.

The TNC and potentially applicable insurers also must disclose to one another a clear description of the coverage, exclusions and limits provided under the TNC insurance arrangement.

Specific statutes can create specific disclosure duties. The absence of a universal pre-suit liability-policy disclosure statute does not mean Montana lacks specialized insurance-information mechanisms.

Coverage-information workflow

Build a written record and identify the legal source for each item of information requested.

Determine whether you are the insured or a third-party claimant. Your relationship to the policy materially affects the disclosure analysis.
Identify the known insurance policy. Preserve the carrier, policy number, named insured, policy period, involved vehicle and claim number.
Request the information in writing. Seek the policy, declarations, applicable limits, excess or umbrella insurance, endorsements and any coverage position relevant to the claim.
Do not overstate the legal basis. If you are a third-party claimant before suit, distinguish a focused request from a claimed universal statutory disclosure right.
Preserve every representation. Record affirmative statements about policy limits, exhaustion, coverage, exclusions, insured status and reservations.
Require a traceable coverage position. A denial should identify the policy language and material facts supporting the result.
Continue the independent coverage investigation. Silence or refusal to volunteer information is not proof that no additional insurance exists.
Provide reasonably available claim information. Comply with reasonable investigative requests so the insurer has a fair opportunity to evaluate liability and damages.
Use specialized statutory mechanisms where they apply. TNC claims and statutory time-limited demands have separate information rules.
If litigation begins, use Rule 26 insurance discovery. Move from informal requests to the formal discovery mechanism for potentially judgment-satisfying insurance agreements.
Maintain one coverage-disclosure record. Track each request, response, representation, refusal, policy received, limit disclosed and unresolved insurance lead.

Maintain a coverage disclosure record

Question Record
Policy identified? Yes / No / Under investigation.
Information requested? Date, recipient, delivery method and exact request.
Complete policy received? Date received and policy period.
Limits disclosed? Amount, coverage, source and date.
Coverage accepted? Preserve written acceptance and applicable coverage.
Coverage denied? Preserve policy provision, factual basis and explanation.
Reservation of rights? Preserve complete letter and all cited provisions.
Excess or umbrella investigated? Confirmed / Denied / Unknown.
Other policies investigated? Owner / driver / employer / commercial / household / TNC.
Representation made? Record exact statement concerning coverage, limits, exhaustion, exclusions or other insurance.
Formal discovery available? Track litigation status and Rule 26 request.

Common coverage-disclosure mistakes

  • Assuming a request automatically creates a legal right to disclosure.
  • Assuming Montana has a universal pre-suit policy-limit disclosure statute.
  • Citing Wilkie as though it decided the underlying disclosure question.
  • Failing to distinguish Montana Supreme Court authority from federal predictions.
  • Confusing nondisclosure with an affirmative coverage misrepresentation.
  • Assuming every § 33-18-201 subsection creates a § 33-18-242 private action.
  • Ignoring the insured's own policy-delivery rights.
  • Failing to obtain a coverage denial or reservation in writing.
  • Failing to preserve affirmative statements about limits or exhaustion.
  • Treating one payment as settlement of every coverage.
  • Ignoring reciprocal claimant-cooperation duties under § 33-18-243.
  • Using an artificially short settlement deadline instead of § 33-18-251.
  • Ignoring special TNC information-exchange rules.
  • Failing to use formal insurance discovery after suit begins.
  • Treating refusal to volunteer insurance information as proof that no other policy exists.

Frequently asked questions

Does Montana require every adverse auto insurer to give me its policy limits before suit?

Montana should not presently be described as having one universal statute imposing that requirement on every liability insurer merely because a third-party claimant requests the information.

Should I still request the complete policy and limits?

Often yes. A focused written request can produce voluntary disclosure, identify the carrier's position, preserve affirmative representations and create a useful claim record. The request itself should not be mischaracterized as proof of a universal statutory disclosure right.

Does Wilkie establish a universal pre-suit disclosure duty?

No. Wilkie reversed a mootness dismissal because the voluntary-cessation doctrine had not been properly applied. The Montana Supreme Court expressly stated that it was not deciding the merits of Wilkie's asserted disclosure duty.

What do Bateman and Amberg say?

Those federal decisions applying Montana law distinguish an affirmative misrepresentation from nondisclosure and reject using § 33-18-201(1) itself as a generalized duty requiring disclosure of requested third-party policy information. They are federal persuasive authority rather than Montana Supreme Court decisions.

If I am the insured, can I obtain my own policy?

The insured's relationship to the policy is materially different. MCA § 33-15-412 addresses delivery of the issued policy to the insured or person entitled to receive it.

Can I formally discover insurance after filing suit?

Yes. Montana Rule of Civil Procedure 26(b)(5) expressly permits discovery of qualifying insurance agreements that may satisfy or reimburse payment of a judgment.

Does every violation of § 33-18-201 support a private lawsuit?

No. The independent action under § 33-18-242 presently identifies only subsections (1), (4), (5), (6), (9), and (13).

Does the claimant have duties during the insurer's investigation?

Yes. Section 33-18-243 requires cooperation with reasonable investigative requests and delivery of reasonably available claim information sufficient to allow fair evaluation.

Can I give an insurer only ten days to accept a policy-limits demand?

A claimant may make settlement proposals, but a demand intended to qualify under MCA § 33-18-251 must comply with that statute, including a response period of at least 60 days and detailed content and documentation requirements.

Are rideshare claims different?

Yes. Montana's TNC statutes contain specialized insurance-investigation provisions requiring exchange of app-status and coverage information that do not apply identically to ordinary private-auto claims.

Coverage transparency is a chain of duties—not one disclosure rule.

Identify who is asking. Identify the policy relationship. Request the information. Preserve every affirmative representation. Require a traceable coverage position. Continue the independent insurance search. Use specialized statutes when they apply. If litigation begins, use formal Rule 26 discovery.

Public legal education only. This page does not create an attorney-client relationship and is not individualized legal advice. Coverage-information rights depend on whether the requesting person is an insured or third-party claimant, the type of insurance, the policy relationship, the claim stage, applicable specialized statutes, reasonably available claim information and whether litigation has begun. Wilkie should not be cited as establishing a universal Montana pre-suit liability-policy disclosure rule. Federal decisions applying Montana law are persuasive rather than controlling state authority. Verify current statutes, court rules, complete official opinions and the operative policy before legal reliance.
