How Long Does a Car Accident Lawsuit Take in Colorado?

Short answer

There is no single timeline. Many Colorado car accident claims settle through insurance within a few months to about a year. If a lawsuit is filed and the case goes all the way to trial, expect roughly 12 to 36 months, with complex cases or appeals adding more time.


In Denver and across the Front Range, the pace depends on medical treatment, the clarity of fault, how busy the court is, and whether the case resolves in mediation. A local attorney can help you balance timing and value so you are not rushed into a low offer.

Key legal deadline to remember

Statute of limitations. Colorado generally gives people injured in motor vehicle crashes three years to file a lawsuit for bodily injury or property damage related to the use or operation of a motor vehicle (C.R.S. 13-80-101(1)(n)). Many other personal injury claims in Colorado carry a two-year deadline.


Government claims. If the at-fault driver was a government employee or the vehicle was owned by a city, county, or the State of Colorado, special rules apply. You must serve a formal notice of claim within 182 days under the Colorado Governmental Immunity Act. Do not wait to get advice if your crash involved a public entity in Denver, Aurora, Lakewood, or nearby communities.

What affects how long a Colorado car accident case takes

  • Severity and complexity of injuries. Ongoing treatment or uncertain prognosis usually extends the timeline.
  • Liability disputes. Clear fault speeds things up, while contested fault slows them down.
  • Number of parties and insurers. Multi-vehicle crashes or commercial policies add layers.
  • Expert needs. Medical experts or accident reconstruction can lengthen discovery.
  • Court backlog. Urban courts like Denver District Court may have heavier dockets.
  • Cooperation on records. Delays in getting medical records or billing slow negotiations.
  • Government defendants. Short notice deadlines and immunity issues create extra steps.
  • Willingness to mediate. Early, realistic mediation can resolve a case sooner.

Typical stages and timeframes

These are general ranges. Every case is different, but this is what we see in Denver, Jefferson, Arapahoe, and Adams County courts.

  1. Immediate post-accident steps (days to weeks)
    Get medical care, follow treatment plans, report the crash to police and your insurer, and preserve evidence like photos, witness contacts, and damage estimates.
  2. Pre-suit insurance negotiations (weeks to months)
    Insurers often investigate and make early offers within a few weeks to a few months. Minor injury claims can settle in 1 to 6 months. Ongoing treatment or low offers can extend this phase.
  3. Filing a lawsuit if settlement stalls (about 1 to 3 months to get started)
    Your lawyer files the complaint, the defendant is served, and an answer is due in a few weeks. The court issues a scheduling order with deadlines.
  4. Discovery (often 6 to 12 months or more)
    Both sides exchange documents, take depositions, secure medical records, and may use experts or independent medical exams. This is often the longest phase.
  5. Motions and pretrial rulings (1 to 6 months)
    The court may consider motions like summary judgment or efforts to limit expert testimony. Briefing and hearings take time.
  6. Mediation or other ADR
    Many Colorado district courts encourage or require mediation. A large share of cases settle at or after mediation.
  7. Trial (often 12 to 36 months from filing)
    Setting a trial date depends on the court’s calendar. Trials in car accident cases typically last 1 to 10 days, with longer trials for complex or catastrophic injuries.
  8. Post-trial and appeals (months to years)
    Post-trial motions and appeals can add significant time. An appeal to Colorado’s appellate courts often takes at least a year.

How long insurance claims take without a lawsuit

  • Quick liability and minor injury. A few weeks to a few months.
  • Moderate injuries with ongoing care. About 3 to 12 months.
  • Disputed or complex claims, including UM/UIM. Many months to years if there are coverage fights or bad-faith issues. UM/UIM stands for uninsured or underinsured motorist coverage.

Common Colorado case examples

  • Minor soft-tissue injury, clear fault. Settles with the insurer in 1 to 4 months.
  • Moderate injury with one surgery, single defendant. Settlement often within is oftenSettlement often 6 to 18 months. If filed and tried, about 12 to 24 months to reach trial.
  • Catastrophic injury, multiple defendants. Two to four years or more through trial, with appeals adding more time.

Costs and attorney fees

Most Colorado car accident attorneys work on a contingency fee. You pay a percentage of the recovery, with a typical fee around one third for settlements and a higher percentage if the case goes to trial.


Cases also have costs such as medical records, filing fees, deposition transcripts, and expert work. Many firms advance these costs and recover them from the settlement or verdict. Longer cases tend to cost more, so a thoughtful strategy weighs timing against value.

Practical tips to keep your case moving

  • Seek prompt medical care and follow your treatment plan.
  • Keep organized records of bills, pay stubs, mileage for appointments, and photos.
  • Respond quickly to your lawyer’s requests for documents and information.
  • Provide full provider lists so medical record requests do not miss anything.
  • Consider early mediation if a fair settlement looks achievable.
  • Be cautious with early low offers before you know your long-term needs.
  • If a government vehicle was involved, speak with counsel right away about the 182-day notice.

Frequently asked questions

Will my case go to trial?

Most Colorado car accident cases settle. Clear liability and well-documented damages make settlement more likely.

Should I wait to settle until I finish treatment?

Often it helps to understand your maximum medical improvement and future care. Waiting too long risks missing deadlines, so track the statute and discuss options with counsel.

What if my insurer denies coverage?

You can sue an at-fault driver and, when appropriate, bring claims against your own insurer for UM/UIM benefits or bad faith. These cases add time but may be necessary to secure full compensation.

What this means for Denver and nearby communities

If your claim is straightforward, you could resolve it through insurance within months. If a lawsuit is needed in Denver, Aurora, Lakewood, Arvada, or Littleton, plan for roughly a year or more to reach trial, often 12 to 36 months depending on the court’s calendar and the complexity of your medical proof.


The best first step is a focused plan that protects deadlines, preserves evidence, and positions you for a fair settlement when the timing is right.
