Many people want to know how long a personal injury lawsuit takes in Montana, but the answer depends on where the matter begins and how it develops. A personal injury claim starts with the insurance company. A personal injury lawsuit begins in court if the parties cannot reach a fair settlement. Some personal injury cases settle in a few months, while others take much longer, depending on the injuries, treatment, and dispute over fault.
At Brann Law Firm, we help clients across Flathead County and beyond understand the process from the start. In Montana, most personal injury lawsuits must be filed within 3 years of the date of the accident, though some claims against government entities may have shorter deadlines. This guide explains the typical timeline for a personal injury claim, what can delay a case, and what to expect at each stage of the legal process.
Early Stages: Filing a Claim and Pre-Lawsuit Timeline
The process starts with notice to the at-fault party’s insurer and your own insurer, if underinsured or med-pay insurance coverage might apply. Your injury claim file opens, and an adjuster is assigned. From there, we gather evidence of fault and damages.
Solid evidence collection builds value and can help a personal injury case timeline move more efficiently. Helpful items include the following:
- Police or crash reports, 911 logs, and any citations issued at the scene
- Medical records, billing statements, diagnostic images, and treatment plans
- Witness names, contact details, and written statements or recordings
- Photos or video of the scene, vehicle damage, and visible injuries
If the claim comes from a car accident, early records can make a major difference in how the insurer evaluates liability and exposure. Getting medical attention right away also helps connect your injuries to the event and creates a cleaner treatment history for your personal injury lawyer and legal team to use later.
Reaching maximum medical improvement (MMI) matters for timing. Settling before your condition stabilizes can shortchange future medical treatment, medical costs, lost wages, lost income, or lasting symptoms. Minor injuries may allow a claim to settle after only a few weeks or months of treatment, while serious, catastrophic, or permanent injuries may prolong the case because the injured person may need ongoing medical care, specialist evaluations, and frequent follow-up appointments.
Once the medical picture is steady, we prepare a formal demand letter or full demand package that explains the facts, the law, and your losses. This package often includes medical records, bills, proof of outstanding medical bills, wage loss information, and an explanation of why you are seeking compensation. The insurer reviews it and responds with an offer, a request for more records, or a denial. If a fair number is not on the table, filing a lawsuit becomes the next step.
This early work sets the foundation for everything that follows, and a thorough file often leads to faster, stronger outcomes at the negotiating table.
The Lawsuit Phase: Filing, Discovery, and Pre-Trial Steps
A claim becomes a lawsuit when we file a Complaint in the proper Montana district court and serve the defendant. Under Montana rules, a defendant typically has 21 days after service to file an Answer. The court then issues a scheduling order that sets deadlines for discovery and motions.
Discovery is the process by which each side tests the case. This discovery phase is a key part of the litigation process. Expect written questions, document requests, depositions, and, if needed, an independent medical exam. In many cases, we also exchange professional reports on medical issues, vocational losses, or accident reconstruction. If liability is disputed, we may also work with accident reconstructionists or other professionals.
Pre-trial motions can speed up or slow down the calendar. Motions to compel discovery, to exclude certain evidence, or for summary judgment can add weeks or months. From filing through the end of discovery, the timeline is typically 6 to 12 months, and complex cases can take longer, especially if the claim involves multiple parties, unclear fault, or substantial financial exposure.
Here is a simple look at common phases and how long they often take in Montana courts.
| Phase | What Happens | Typical Time Range |
| Claim Setup and Records | Open a claim, gather medical and accident proof | 6 to 16 weeks, longer with serious injuries |
| Demand and Negotiation | Send demand, review offers, and counter | 3 to 12 weeks |
| Lawsuit Filing and Answer | File Complaint, serve parties, receive Answer | 4 to 10 weeks |
| Discovery | Exchange documents, depositions, and professional reports | 6 to 12 months, or longer if complex |
| Motions and Pre-Trial | Evidence motions, mediation, final trial prep | 1 to 4 months |
| Trial | Jury selection, testimony, verdict | 2 days to 2 weeks, sometimes more |
| Post-Trial | Judgment entry, post-trial motions, potential appeal | 1 month to over a year if appealed |
With those building blocks in mind, the next question is whether your personal injury case resolves through the settlement process or continues until the case goes to trial.
Settlement Timeline vs. Going to Trial
Most personal injury cases settle without a trial. Settlement can happen before suit, during discovery, or shortly before a trial date. The sweet spot often comes after both sides have seen the key evidence and the risk has become clearer.
Mediation is a structured settlement meeting with a neutral mediator. Sessions often last a full day, with a week or two of prep and document exchange leading up to it. Back-and-forth negotiations outside mediation can span several rounds over 30 to 90 days. In many cases, personal injury cases settle once both sides have a better sense of medical damages, liability risk, and likely jury appeal.
When a case resolves, the parties usually sign a settlement agreement and proceed to the final settlement stage. That often includes addressing medical liens, resolving outstanding medical bills, and making sure settlement funds are distributed correctly.
Cases that go to trial take longer for two reasons: more preparation and court scheduling. Witnesses, professional testimony, exhibits, and motions require extensive coordination. Pre-suit settlements often occur within 3 to 9 months, while litigation cases can take 9 to 18 months to resolve, and cases that go to trial can add extra time. If the case goes to trial, the injured party and their legal team should expect more formal preparation and a longer overall timeline.
If the settlement fails, the case moves forward to a judge and jury to decide liability and damages.
Trial and Post-Trial Timeline in Montana
The trial starts with jury selection, then opening statements. Each side presents witnesses and exhibits, followed by closing arguments. The jury deliberates and returns a verdict, which the court records as a judgment.
Many personal injury lawsuits that reach trial run 3 to 7 days. Multi-vehicle crashes, brain injuries, or claims involving multiple parties and heavy professional testimony can run longer. Court calendars in Flathead County and nearby districts can also push a trial date by several weeks or more.
Post-trial steps include entry of judgment and possible motions to adjust the verdict or seek a new trial. An appeal prolongs the case, often for many months. Payment of a settlement or judgment can also take additional time if liens or subrogation claims must be resolved before the client receives settlement funds.
Understanding what affects timing helps you plan, which brings us to the factors that affect how long an injury lawsuit may last.
Factors That Affect How Long a Case Takes
Injury severity plays a big role. If you need surgery or long-term therapy, we often wait until MMI to capture future costs and permanent effects. Early settlements, while treatment is still evolving, can undervalue your claim.
Timing shifts when there are multiple parties, unclear fault, or low policy limits. If the insurance company does not admit fault, or if the claim involves multiple parties, deeper discovery and more professionals are often needed. Limited insurance can lead to faster tenders or to underinsured motorist claims that add months.
Delays often stem from slow record retrieval, incomplete medical charts, or insurer tactics such as piecemeal requests. Clear and complete documentation helps close those gaps. Here are common slowdowns to watch for:
- Missing medical bills or duplicate records that require re-requests
- Gaps in treatment that make the insurer question causation or damages
- Late witness interviews leave unanswered questions about fault
- Scheduling conflicts for depositions or professional exams
Certain factors can also affect how long a case takes, including whether liability is clear, whether the other party disputes liability for damages, whether the injured person has reached maximum medical improvement, and whether the case involves serious or minor injuries. These are some of the main things that affect how long a claim may take to settle.
You can take steps that keep your case moving. These practical actions help reduce back-and-forth and keep the focus on resolution:
- Get care early and follow your treatment plan without long breaks
- Save every bill, EOB, prescription receipt, and mileage log for medical visits
- Respond quickly to requests for information, signatures, or appointments
- Avoid broad social media posts about the crash or your recovery
- Track missed work, job duty changes, and out-of-pocket costs in a simple spreadsheet
Montana’s timeline rules also matter. Most injury lawsuits carry a three-year filing deadline, and special notice rules can apply to government defendants. Different timing rules apply in medical negligence cases, including those involving minors, so early legal guidance from an experienced personal injury attorney is wise.
