Utah Personal Injury Statute of Limitations: How Long You Have to Sue
Short answer: Most Utah personal injury claims — car accidents, slip and falls, and similar negligence-based injuries — generally must be filed within 4 years of the injury under Utah Code §78B-2-307. Some claim types have shorter deadlines, most notably claims against a government entity, which can require formal notice within a matter of months — far shorter than the general 4-year window.
Who this guide is for
Anyone in Utah with a personal injury and wants to understand the deadline for filing a lawsuit — not just for settlement negotiations, which can continue informally, but for the hard legal deadline to actually sue.
The general rule: 4 years
For most negligence-based personal injury claims, Utah Code §78B-2-307 sets a 4-year deadline from the date of the injury. This is the default that applies to most car accident, slip-and-fall, and similar cases.
Why "4 years" isn't the end of the analysis
Several important exceptions and variations can change this general rule:
- Claims against government entities (a city, county, or state agency) generally require a formal notice of claim within a much shorter window — commonly cited as around one year — before a lawsuit can even be filed. Missing this notice deadline can bar the claim entirely, regardless of the general 4-year statute.
- Minors — if the injured person was under 18 at the time, the deadline may be tolled (paused) until they turn 18, giving them time after reaching adulthood to file, depending on the specific circumstances.
- Medical malpractice and certain other specialized claim types can have their own distinct, shorter deadlines and discovery rules, separate from the general personal injury statute.
- Wrongful death claims have their own statute of limitations, generally measured from the date of death rather than the date of the underlying injury — see Utah Wrongful Death Claims.
Why this deadline matters so much
Missing the statute of limitations generally means permanently losing the right to sue, regardless of how strong the underlying claim was. This isn't a soft guideline — courts generally enforce it strictly, and an insurance company negotiating in apparent good faith right up until the deadline passes doesn't extend it.
Don't rely on ongoing settlement talks to protect your deadline
A common and costly mistake: assuming that because an insurance company is still discussing your claim, the deadline to sue isn't approaching. Settlement negotiations and the statute of limitations are separate tracks — if negotiations stall or the deadline is approaching, you may need to file suit to preserve your rights, even while continuing to negotiate.
Frequently asked questions
Does the 4-year clock start from the accident date or when I discovered my injury? For most claims, it generally starts from the date of the injury itself — though some situations involve a "discovery rule" that can affect when the clock actually starts, particularly for injuries not immediately apparent.
What if I'm still receiving medical treatment when the deadline approaches? Ongoing treatment doesn't extend the filing deadline — this is exactly the kind of situation where consulting an attorney well before the deadline matters, so a lawsuit can be filed to preserve your rights even if treatment and damages are still evolving.
How do I find out if my specific claim involves a government entity with a shorter deadline? If your injury involved a government vehicle, government property, or a government employee acting in their official role, treat this as a strong signal to get legal advice immediately, given how much shorter and more procedurally strict government claim deadlines generally are.
