How Montana\'s framework works in practice

Montana has never adopted a no-fault auto-insurance system. Every Montana-registered driver carries liability coverage in the statutory minimum amount of 25/50/20, and claims against that policy require proof of fault.

Without no-fault, Montana claims move through traditional tort procedure: medical bills are pursued against the at-fault liability carrier, fault is contested, and comparative-negligence rules determine the final recovery. The system places more weight on the plaintiff's ability to document fault.

MedPay coverage in Montana

Montana insurers must offer MedPay coverage but drivers can decline it. The downstream consequence: more Montana crash claims involve medical-lien negotiations, ERISA reimbursement disputes, and balance-billing arguments because there is no statutory first-payer.

Minimum-liability coverage in Montana

Montana statutory minimum coverage is 25/50/20. Many Montana drivers carry only the minimum, which is why uninsured- and underinsured-motorist coverage on the plaintiff's own policy is the single most important coverage to verify in serious injury cases.

The Montana claim process: from accident to recovery

The standard Montana claim process treats the at-fault carrier as the first source of recovery. If that policy is inadequate, secondary sources include the plaintiff's own UM/UIM coverage, any applicable umbrella policies, and (in third-party-defendant cases) the assets of co-defendants. Each tier requires separate notice, separate documentation, and separate negotiation strategy. Missing a notice deadline on any tier can extinguish that source of recovery entirely.

Montana auto-insurance carrier landscape

The carriers operating in Montana apply different claim-handling protocols depending on the policy type, the insured's tenure, and the claim severity. Soft-tissue claims under $25,000 typically go to a fast-track adjuster; claims over that threshold and any with permanent-injury indicators move to a senior adjuster or a litigation-prep team. Knowing which adjuster handles which case type helps plaintiffs' lawyers route demands to the right person.

How Montana's framework looks in real cases

A common Montana scenario involves a slip-and-fall at a chain retailer where the defendant initially denies liability based on the "open and obvious" defense. The plaintiff's case is built through surveillance-video preservation letters (sent within seven days of the fall), photographs of the unsafe condition before it is repaired, witness statements from store employees, and Montana's premises-liability case law on the storekeeper's duty of care. Cases that look unwinnable based on initial police-report-style summaries often resolve at six- or seven-figure values once a complete record is built.

Common mistakes that reduce Montana case value

Plaintiffs in Montana commonly underestimate the procedural complexity of personal-injury litigation. Common oversights include failing to identify all potential defendants (especially in commercial-vehicle cases where the driver, owner, and employer are often different entities), failing to preserve electronic evidence (text messages, GPS data, telematics), and failing to comply with policy-condition deadlines (e.g., examinations under oath for UM claims). Each oversight is recoverable if caught early but irreversible if caught late.

What this means for case value

In at-fault Montana, your case value depends on (1) the at-fault driver's liability limits, (2) UM/UIM coverage on your own policy when those limits are inadequate, and (3) the comparative-fault rule that reduces recovery by your percentage of fault.
