I want to know if I can get help with filing a lawsuit for unlawful arrest.
Yes there was and I don't know the exact date I was arrested. Some time in November but my case was dismissed April 1st.
Attorney Answer
Yes — an arrest without probable cause, followed by dismissed charges, can support a civil rights claim against the officers and the government agency involved, and the deadline for that federal claim is longer than the one-year notice rule you may have heard about.
42 U.S.C. § 1983 allows you to sue a person acting under color of state law — including a police officer — for violating your Fourth Amendment right to be free from arrest and seizure without probable cause.
The dismissal helps you. The U.S. Supreme Court held in Thompson v. Clark, 596 U.S. 36 (2022) — binding nationwide — that you need only show your prosecution ended without a conviction; no affirmative indication of innocence is required. A dismissal fits that standard. And if officers procured the legal process and your resulting seizure using a statement they knew was untrue or recklessly disregarded as untrue, that can independently support a claim, as the Tenth Circuit — which covers Utah, making it binding here — recognized in Sanchez v. Hartley, 810 F.3d 750 (10th Cir. 2016).
Now the notice-of-claim rule, because it does not reach as far as it looks. If you add Utah state-law claims — false arrest, false imprisonment, malicious prosecution — against a Utah city, county, or state agency or its employees, Utah Code § 63G-7-401 and § 63G-7-402 require a written notice of claim filed with that entity within one year after the claim arises, and missing that deadline can bar those state claims entirely. It does not bar your federal claim. In Felder v. Casey, 487 U.S. 131 (1988), the U.S. Supreme Court held that state notice-of-claim requirements are preempted as inconsistent with federal law when applied to claims under 42 U.S.C. § 1983. So even if that one-year notice window has already closed, your § 1983 claim against the officers is still alive: in Utah it borrows the state's four-year residual limitations period, Utah Code § 78B-2-307 (Fratus v. DeLand, 49 F.3d 673 (10th Cir. 1995); Garza v. Burnett, 672 F.3d 1217 (10th Cir. 2012)). Dates still matter, though — a Fourth Amendment false-arrest claim generally starts running when you were first held under legal process, not when the charges were dismissed — so pinning down the exact arrest and arraignment dates is worth doing now.
What you can do
1) Contact a Utah civil-rights attorney soon — the one-year notice of claim needed for any state-law claims against a city, county, or agency is short and generally cannot be extended once it passes, even though your federal § 1983 claim has longer to run.
2) Pin down the exact arrest date using the police report, booking records, or court file, since that date likely controls your deadline.
3) Request the complete police report, any body camera footage, and the dismissal order from the court.
4) Write down everything you remember about the arrest — what officers said, the stated reason for the arrest, and any witnesses present — while it is still fresh.
5) Do not sign anything from the city, county, or their insurer, and do not accept a settlement, before speaking with an attorney.
Time limits: Utah's governmental-immunity rules — written notice of claim to the entity within one year after the claim arises, then a waiting period before suit — govern Utah state-law claims against a governmental entity, not your federal claim. A § 1983 claim in Utah borrows the state's four-year residual limitations period, Utah Code § 78B-2-307. Exactly which date starts each of those clocks in your case is a fact-specific legal question, so get an individual case review from a Utah attorney now.

Frequently Asked Questions
What must I prove for a Fourth Amendment false-arrest claim under Section 1983?
Generally, that a person acting under color of state law — such as a police officer — arrested or seized you without probable cause, in violation of your Fourth Amendment rights.
Does my criminal case need to have ended with a declaration of innocence to sue for wrongful prosecution?
No. The U.S. Supreme Court has held that a plaintiff only needs to show the criminal prosecution ended without a conviction, not that it ended with some affirmative indication of innocence.
What is a "notice of claim" and why does it matter when suing a Utah government agency?
It is a formal written notice that Utah law requires be filed with a governmental entity before suing the entity or its employees on a state-law claim, generally within one year after the claim arises, and missing it can bar that state claim regardless of its merit. It does not apply to a federal claim under 42 U.S.C. § 1983: in Felder v. Casey, 487 U.S. 131 (1988), the Supreme Court held state notice-of-claim requirements are preempted when applied to § 1983 claims, which in Utah borrow the state's four-year residual limitations period, Utah Code § 78B-2-307.
