Deadline to Sue Over a Contract in Idaho
How long you have to sue over a broken written contract in Idaho, 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 Idaho
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 Idaho | What it means |
|---|---|---|
| Standard deadline | 5 years | The general limitations period to file a written-contract claim. |
| Statute | Idaho Code §5-216 | The controlling statute for the limitations period. Read the full text through the source link below. |
When it starts
The five years generally runs from the breach, when the other side fails to perform, not from when you discover the problem. Idaho treats an ordinary contract claim as accruing at breach, so a breach found late usually does not reset the clock.
Discovery rule No general rule
Narrow. Idaho generally starts the clock at breach for ordinary written contracts rather than at discovery. A delayed start can apply where a claim sounds in fraud or where fraudulent concealment hides the breach, but the default under §5-216 is accrual at breach.
Statute of repose: None
No general statute of repose for ordinary written contracts. The five-year period under §5-216 runs from breach. Specialized claims such as construction or improvements to real property carry their own outer limits, but those are not the general contract clock.
| Deadlines that can differ | Period | What it means |
|---|---|---|
| Oral or unwritten contract | 4 years | An action on a contract not founded on a writing must be filed within four years under Idaho Code §5-217, one year shorter than the written period. Whether your agreement counts as written can decide which deadline applies. |
| Sale of goods (UCC) | 4 years | A contract for the sale of goods runs on Idaho Code §28-2-725: four years from when the breach occurs, with warranty claims accruing at delivery regardless of your knowledge. Parties may agree to shorten it to no less than one year but may not extend it. |
What you can do right now
Concrete, neutral steps if a contract was broken in Idaho and the clock is running. This is legal information, not legal advice.
- Fix the breach date and confirm the contract is written
Write down when the other side broke the agreement and confirm you have a signed writing. In Idaho a written contract carries five years under §5-216, but an oral one is only four under §5-217, so the paper trail matters.
- Count from the breach, not from discovery
Idaho generally starts the five years at the breach, not when you found out. Unless fraud or concealment applies, a late-found breach will not reset the clock, so act as soon as you learn of it.
- If goods were sold, check the UCC clock
A sale of goods runs on Idaho Code §28-2-725, a four-year rule that accrues at delivery for warranty claims. Confirm whether your deal is a sale of goods rather than a services or general contract.
- Talk to an Idaho attorney before the deadline
Whether a contract is written, when it was breached, and whether any exception applies all turn on your facts. A licensed Idaho attorney can confirm your exact deadline, and the Idaho State Bar can refer you to one.
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 Idaho contract claimants get wrong
The costly mistake in Idaho is assuming every agreement carries the same deadline. A written contract gives you five years under Idaho Code §5-216, but an oral or unwritten one gives you only four under §5-217. That one-year gap is smaller than in many states, yet it still decides whether a claim near the edge is alive or dead, so whether your deal counts as founded on a writing matters. The clock generally starts at the breach, when the other side fails to perform, not when you learn of the problem. Idaho does not apply a broad discovery rule to ordinary contracts, so a late-found breach usually does not reset the five years unless fraud or concealment is involved. One more wrinkle catches people out. A sale of goods runs on Idaho Code §28-2-725, a separate four-year rule with its own accrual at delivery, not the general §5-216 clock. If your deadline is close, pin down the breach date and the form of the contract first.
Common questions
What is the statute of limitations on a written contract in Idaho?
Five years from the breach, under Idaho Code §5-216, for an action on a contract founded on a written instrument. 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 Idaho?
Four years, under Idaho Code §5-217, one year shorter than the five-year written-contract period. Because the periods differ, whether your agreement counts as written or oral can decide whether your claim is still timely.
Does the five years start at the breach or when I found out?
Generally at the breach. Idaho starts the clock when the contract was broken for ordinary written contracts under §5-216. A later start can apply only in narrow situations such as fraud or concealment.
Is a contract to buy goods still five years in Idaho?
No, it is four years under a different statute. A sale of goods is governed by Idaho Code §28-2-725, a four-year period that accrues at delivery for warranty claims regardless of your knowledge. Parties can shorten it to no less than one year but cannot extend it.
