Deadline to Sue Over a Contract in Wyoming
How long you have to sue over a broken written contract in Wyoming, the statute of limitations, plus when the clock starts, the shorter deadline for oral contracts, and the four-year UCC rule for a sale of goods. Cited to the statute.
How the deadline works in Wyoming
When the clock starts, whether a discovery rule can delay it, and the deadlines that differ for oral contracts and a sale of goods.
| How the clock works | In Wyoming | What it means |
|---|---|---|
| Standard deadline | 10 years | The general limitations period to file a written-contract claim. |
| Statute | Wyo. Stat. §1-3-105(a)(i) | The controlling statute for the limitations period. Read the full text through the source link below. |
When it starts
The ten years generally runs from when the breach occurs. Wyoming measures from accrual at breach for an ordinary contract, so the clock starts when performance was due and missed, not when you later discover the loss.
Discovery rule Yes
Limited. Wyoming recognizes a discovery rule for some claims, delaying accrual until the plaintiff knew or reasonably should have known of the injury, but for an ordinary written contract the default is accrual at breach. Treat delayed discovery as a fact-specific exception rather than the norm.
Statute of repose: None
No general statute of repose for ordinary written contracts. The ten-year period runs from breach or accrual. Improvements to real property carry a separate outer limit under a different statute, but that is not the general §1-3-105 contract clock.
| Deadlines that can differ | Period | What it means |
|---|---|---|
| Oral or unwritten contract | 8 years | A contract not in writing gets eight years under Wyo. Stat. §1-3-105(a)(ii), two years shorter than the written period. Whether an agreement counts as written can shift the deadline, though even the oral window here is long by national standards. |
| Sale of goods (UCC) | 4 years | A contract for the sale of goods runs on Wyo. Stat. §34.1-2-725: four years from when the breach occurs, far shorter than the general contract periods. Warranty claims accrue at delivery regardless of your knowledge, and parties may shorten the period to no less than one year but may not extend it. |
| Long windows, but the UCC is short | 10 or 8 years versus 4 years | Wyoming gives general contracts unusually long deadlines, which makes the short four-year UCC clock easy to overlook. Confirm whether your deal is a sale of goods before you assume ten or eight years. |
What you can do right now
Concrete, neutral steps if a contract was broken in Wyoming and the clock is running. This is legal information, not legal advice.
- Confirm the contract is written
Wyoming gives a written contract ten years under §1-3-105(a)(i), but an oral one eight under §1-3-105(a)(ii). Both are long, yet confirming you have a writing still fixes the right period.
- Fix the breach date
Write down when the other side broke the agreement. The clock generally runs from that breach, not from when you found out, even though Wyoming’s long windows give you more room than most states.
- If goods were sold, check the short UCC clock
A sale of goods runs on Wyo. Stat. §34.1-2-725, only four years and much shorter than the general contract periods. Confirm whether your deal is a sale of goods, because the long ten-year window will not apply.
- Talk to a Wyoming attorney before the deadline
Whether your contract is written, when it accrued, and whether the UCC governs all turn on your facts. A licensed Wyoming attorney can confirm your exact deadline before it runs.
This is general legal information, not legal advice. Deadlines turn on the specific facts of your case, and exceptions cut both ways, so confirm your date with a licensed attorney before relying on it.
What Wyoming contract claimants get wrong
Wyoming gives contract claims some of the longest deadlines in the country, and that generosity is exactly what makes the short exception dangerous. A written contract carries ten years under §1-3-105(a)(i), and even an oral one gets eight under §1-3-105(a)(ii), so the written-versus-oral split matters less here than almost anywhere else. The clock generally starts at the breach, when performance was due and missed, not when you discover the loss. Wyoming recognizes a discovery rule for some claims, but for an ordinary written contract the default is accrual at breach. The trap sits in the sale-of-goods rule: a UCC claim under §34.1-2-725 runs only four years, far shorter than the ten or eight you might expect, and it accrues at delivery for warranty claims regardless of your knowledge. If your dispute involves goods, do not lean on the long general windows. Otherwise, Wyoming gives you unusually generous time, but confirm the breach date all the same.
Common questions
What is the statute of limitations on a written contract in Wyoming?
Ten years from the breach, under Wyo. Stat. §1-3-105(a)(i), one of the longest written-contract periods in the country. The clock generally runs from when the contract was broken, not from when you discovered it.
How long do I have to sue on an oral contract in Wyoming?
Eight years, under Wyo. Stat. §1-3-105(a)(ii), two years shorter than the written-contract period. Even the oral window is long by national standards, but confirming the form of the contract still fixes the right deadline.
When does the ten-year clock start in Wyoming?
Generally at the breach, when performance was due and missed. Wyoming recognizes a discovery rule for some claims, but for an ordinary written contract the default is accrual at breach.
Is a contract to buy goods still ten years in Wyoming?
No. A sale of goods is governed by Wyo. Stat. §34.1-2-725, a four-year UCC period that accrues at delivery for warranty claims regardless of your knowledge. It is far shorter than the general ten-year contract window.
