Start with the problem you are trying to solve

A crash does not create one legal problem. It can create several at once: liability, insurance identification, insured status, medical treatment, first-party coverage, evidence preservation, claim handling, reimbursement and settlement. Start with the immediate question and then follow the linked pathway.

Core workflow: find the facts → find the insurance → read the policy → identify the law → preserve the evidence → document the damages → resolve reimbursement → only then make the claim final.

Montana auto-insurance law at a glance

Liability minimum 25 / 50 / 20

MCA § 61-6-103 establishes minimum bodily-injury and property-damage liability protection.

Permissive users Statutory protection

Montana's required owner policy protects the named insured and qualifying express or implied permissive users, subject to the governing statutes.

Uninsured motorist Included unless rejected

MCA § 33-23-201 requires UM bodily-injury protection unless the named insured rejects the coverage.

Underinsured motorist Check the policy

UIM is not generally mandated by § 33-23-201. Determine whether it was purchased and how the policy defines and limits the coverage.

Comparative negligence 50% may recover

Claimant negligence of 50% or less can reduce recovery proportionately. Negligence greater than the applicable opposing negligence bars recovery.

Medical damages 2021 law matters

MCA § 27-1-308 changed the measure and evidence of recoverable medical expenses for modern bodily-injury and death claims.

Claim practices UTPA

MCA § 33-18-201 regulates investigation, communication, coverage decisions and settlement conduct by insurers.

Statutory time-limited demand At least 60 days

A demand intended to qualify under § 33-18-251 must satisfy detailed statutory form, content, documentation and timing requirements.

Subrogation Made whole matters

Montana maintains substantial made-whole protections, but the analysis depends on the covered loss and can be altered by special statutory or federal reimbursement regimes.

A statutory minimum is a floor—not a coverage finding. The actual claim may involve higher liability limits, another owner policy, commercial insurance, umbrella coverage, UM/UIM, MedPay or multiple policies.
Source-control rule: current Montana statutes and official court opinions control. Verify the operative policy, statute, complete opinion and current treatment before legal reliance.

Browse the complete Montana library

Search by issue or filter by stage of the claim. The pages are deliberately connected so that a reader can move from a practical problem to the policy, statute, cases and next workflow.

Coverage, insured status & policy rights

Start here when the central question is what insurance exists and whether it applies.

A practical Montana crash-claim workflow

The order matters. Many avoidable claim problems arise because settlement, recorded statements or coverage conclusions occur before the underlying facts and insurance have been mapped.

Protect people and comply with crash duties. Address medical safety, law-enforcement reporting and immediate scene obligations first.
Preserve the evidence. Photograph the scene, locate witnesses, identify cameras and protect vehicle and electronic evidence before it disappears.
Identify the driver, owner and every potentially responsible party. Do not assume the person holding the insurance card is the only relevant insured, policy source or defendant.
Find every insurance policy. Search owner, driver, household, employer, commercial, umbrella, rental, rideshare and first-party coverage.
Obtain and read the complete policies. Use the declarations, definitions, insuring agreements, exclusions, conditions and endorsements together.
Determine who qualifies as an insured. Insured status can differ among liability, UM/UIM, MedPay, umbrella and commercial coverage.
Map liability and comparative fault. Test every actor's conduct against Montana law and the preserved evidence. Do not treat an adjuster's percentage as the final legal determination.
Build the medical and damages record. Track diagnosis, causation, treatment, amounts paid or owing, wage loss, future care, earning capacity and actual life consequences.
Evaluate insurer conduct separately from the underlying coverage dispute. A debatable policy question and an unreasonable investigation are not necessarily the same issue.
Protect UM/UIM before releasing the tortfeasor. Identify all liability insurance, provide appropriate notice and address subrogation and possible stacking before signing a liability release.
Resolve medical reimbursement. Identify MedPay, health insurance, Medicare, Medicaid, ERISA and workers' compensation interests before distributing settlement proceeds.
Make settlement the final step. Only after coverage, damages, future care, reimbursement, remaining defendants and release language are understood should the claim become final.

Move from citizen guidance to primary authority

VictimsGuide is designed to make legal research traceable. Each citizen page identifies the statutes and leading decisions behind the practical workflow so the reader can move from explanation to authority rather than relying only on an adjuster's summary or an internet article.

Montana Case Authority Library

Search leading Montana cases by doctrine: UM/UIM, stacking, policy interpretation, claims handling, duty to defend, agents, settlement, made whole, evidence, damages and wrongful death.

Start with mandatory coverage

For an unfamiliar Montana claim, begin with the statutory liability floor, then build outward to actual policy limits and additional coverage.

Research discipline: the statute in force on the relevant date, the complete insurance policy and the current treatment of the controlling case all matter. Older Montana cases may have been affected by later legislation—particularly stacking and medical-damages law.

Why this library exists

A serious crash places an ordinary citizen inside several professional systems at the same time: law enforcement, insurance claims, medical billing, health coverage, vehicle repair, evidence preservation and possibly litigation.

Each institution sees only part of the problem. The injured person is often the only person who must eventually understand how all of those parts fit together.

This Montana library is designed to make that process visible:

  • what insurance must exist;
  • what insurance may additionally exist;
  • who is protected;
  • what the policy actually says;
  • what the insurer must do;
  • what evidence should be preserved;
  • how Montana allocates fault;
  • how damages are proved;
  • who may claim reimbursement;
  • and what must be understood before a release makes the claim final.

Do not reduce a serious crash to a claim number.

Build the record. Find the insurance. Read the policy. Preserve the evidence. Identify the controlling Montana law. Document the actual loss. Resolve competing payment rights. Then decide whether settlement produces a fair and informed final result.

Public legal education only. VictimsGuide.com does not provide individual legal representation through this library, and use of these materials does not create an attorney-client relationship. Montana insurance and crash claims depend on the facts, policy language, applicable policy period, statutes, regulations, case law, procedural rules and current treatment of authorities. Government, commercial, interstate, federal, workers' compensation, ERISA, Medicare, Medicaid, wrongful-death and other specialized claims may involve additional rules and deadlines. Verify controlling authority before reliance.
