Montana Bad Faith Law: What Qualifies

Montana Code Annotated §33-18-201 defines unfair claim settlement practices. Under Montana law, bad faith includes:

Montana recognizes both statutory unfair claim practices and common law bad faith tort. Successful bad faith claims can result in compensatory damages, consequential damages, and in some cases punitive damages.

Step-by-Step: How to File a CSI Complaint

Step 1: Gather Your Documentation

Before filing, compile a complete documentation package. CSI complaints with strong evidence produce better outcomes.

  • Policy declarations page and relevant policy sections
  • Claim number and date of loss
  • All correspondence with the carrier (emails, letters, adjuster notes)
  • Carrier's estimate and any denial letters
  • Contractor estimates with line-item breakdowns
  • Photos and videos of damage
  • Timeline of key events (loss date, claim filed, adjuster visit, estimate received, demands sent, responses)
  • Any demand letters you've sent

Step 2: File Your Complaint Online or by Phone

Online (recommended): Visit csi.mt.gov/consumers/file-a-complaint. Complete the online form with:

  • Your contact information
  • Insurance company name and policy number
  • Claim number and date of loss
  • Detailed description of the problem (be specific: what happened, when, what you've tried, why the carrier's position is wrong)
  • Upload supporting documents (estimates, photos, correspondence)

By phone: Call 1-800-332-6148 or 406-444-2040. A CSI representative will help you file and may request documents by email or mail.

By mail: Download the complaint form from CSI's website, complete it, and mail with copies of supporting documents to the address above.

Step 3: CSI Reviews and Contacts the Carrier

After you file:

  1. CSI acknowledges receipt — Usually within 2-5 business days via email or mail
  2. CSI forwards complaint to carrier — Carrier has 21 days to respond in writing
  3. Carrier must provide written explanation — Must address each issue you raised and provide documentation
  4. CSI reviews carrier's response — Determines if carrier violated Montana law or policy terms

Step 4: CSI Investigation and Resolution

CSI may:

  • Require corrective action — If carrier violated law, CSI can order compliance
  • Facilitate settlement discussions — Regulatory pressure often prompts better offers
  • Close complaint if no violation found — CSI provides explanation
  • Refer to enforcement — Serious or repeated violations may result in fines or sanctions

You receive copies of all correspondence. Most complaints resolve within 30-90 days.

Days 30-45: If no movement, escalate to claims supervisor. Request written explanation of valuation or denial.

Days 45-60: If still no resolution, file CSI complaint. Regulatory pressure often changes carrier's position.

Days 60-90: CSI investigates. Carrier must respond. Many claims settle during this period.

Montana recognizes both statutory and common law bad faith claims.

How long does CSI take to resolve complaints?

Most CSI complaints receive initial response within 10-15 business days. Full investigation typically takes 30-90 days depending on complexity. The carrier must respond to CSI within 21 days of notification.

Can CSI force my insurance company to pay my claim?

CSI cannot order a specific settlement amount, but can investigate unfair practices and require the carrier to correct violations. Regulatory pressure often prompts better offers. For payment disputes, you may need appraisal or litigation.

What documentation do I need to file a CSI complaint?

Gather: policy documents, claim correspondence, adjuster estimates, contractor bids, photos of damage, timeline of events, and any demand letters sent. Strong documentation increases likelihood of favorable outcome.

Will filing a complaint affect my insurance rates?

No. Montana law prohibits carriers from raising rates or canceling policies in retaliation for filing complaints. If you experience retaliation, file an additional complaint with CSI.

What happens after I file a CSI complaint?

CSI reviews your complaint, contacts the carrier, and requests a written response. The carrier must respond within 21 days. CSI investigates and may require corrective action. You receive copies of all correspondence.

Can I file a complaint if my claim was denied?

Yes. If the denial was improper, lacked investigation, or violated policy terms, CSI can investigate. Include documentation showing why the denial was wrong and what policy language supports coverage.

Should I hire a lawyer before filing a CSI complaint?

Not required. Most policyholders file complaints themselves. However, if the claim involves significant money, bad faith, or complex coverage issues, consulting a Montana insurance attorney can help.

What is the deadline to file a CSI complaint?

No specific deadline, but file as soon as possible. Delays weaken your case. If you're considering litigation, note that Montana has an 8-year statute of limitations for breach of contract and 3 years for bad faith tort claims.
