Deadline to Sue Over a Contract in Montana
How long you have to sue over a broken written contract in Montana, 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 Montana
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 Montana | What it means |
|---|---|---|
| Standard deadline | 8 years | The general limitations period to file a written-contract claim. |
| Statute | Mont. Code Ann. §27-2-202(1) | The controlling statute for the limitations period. Read the full text through the source link below. |
When it starts
The eight years generally runs from the breach, when the other side fails to perform, not from when you learn of it. For an installment or continuing obligation, a fresh eight-year clock can run from each missed performance. A late-found breach usually does not reset the clock outside a narrow discovery exception.
Discovery rule Yes
Limited. Montana accrues a contract claim at the breach by default. A discovery exception can delay accrual where the facts of the claim are concealed or otherwise not knowable, but it is narrow and the ordinary contract clock runs from the breach itself.
Statute of repose: None
No general statute of repose for ordinary written contracts, so the eight-year clock runs from the breach. Claims over construction and improvements to real property carry their own separate outer limit under Montana law, but that repose does not govern the general contract deadline.
| Deadlines that can differ | Period | What it means |
|---|---|---|
| Oral or unwritten contract | 5 years | A contract, account, or promise not founded on a written instrument runs five years under Mont. Code Ann. §27-2-202(2), shorter than the eight-year written period. Whether an agreement counts as founded on a writing can therefore decide your deadline. |
| Sale of goods (UCC) | 4 years | A sale of goods runs on Mont. Code Ann. §30-2-725, four years from the breach, with warranty claims accruing at delivery regardless of your knowledge. That is shorter than both the eight-year and five-year contract periods, so confirm whether your deal is a sale of goods. |
| Account or open account | 5 years | An action on an open account that is not founded on a written instrument falls under the five-year period in §27-2-202(2), not the eight-year written rule. Confirm whether your dispute rests on a signed writing before assuming eight years. |
What you can do right now
Concrete, neutral steps if a contract was broken in Montana and the clock is running. This is legal information, not legal advice.
- Confirm the contract is founded on a writing
Montana gives eight years under §27-2-202(1) only to a contract founded on a written instrument. If your deal was oral or an open account, it drops to five years under §27-2-202(2), so the written form is what unlocks the longer period.
- For installment deals, count from each missed payment
If the contract calls for ongoing performance, each separate breach can start its own eight-year clock. That can keep newer claims alive while barring older ones, so map every date before assuming the whole dispute is timely.
- If goods were sold, check the UCC clock
A sale of goods runs on Mont. Code Ann. §30-2-725, 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, because it is shorter.
- Talk to a Montana attorney before the deadline
Whether your agreement is founded on a writing, and when it was breached, turn on your facts. A licensed Montana attorney can confirm your exact deadline before the eight years 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 Montana contract claimants get wrong
Montana gives written contracts an unusually generous eight years, and that length is exactly why the written-versus-oral line matters here. A contract founded on a written instrument carries eight years under Montana Code Annotated section 27-2-202(1), while a contract, account, or promise not founded on a writing gets only five years under section 27-2-202(2). Whether your agreement counts as founded on a writing can therefore add or subtract three years from your deadline. The clock usually starts at the breach, when the other side fails to perform, not when you discover it, and Montana applies only a narrow discovery exception for concealed or unknowable facts. A sale of goods is the short outlier, running four years under section 30-2-725 with accrual at delivery for warranty claims. If your deadline is approaching, pin down whether the deal rests on a signed writing and fix the exact breach date before relying on the full eight years.
Common questions
What is the statute of limitations on a written contract in Montana?
Eight years from the breach, under Mont. Code Ann. §27-2-202(1), for a contract founded on a written instrument. That is one of the longer written-contract deadlines in the country, and the clock generally runs from when the contract was broken.
How long do I have to sue on an oral contract in Montana?
Five years, under Mont. Code Ann. §27-2-202(2), for a contract, account, or promise not founded on a written instrument. That is three years shorter than the written period, so the form of the deal matters.
When does the eight years start in Montana?
Generally at the breach. Montana measures from when the contract was broken, not from discovery, and applies only a narrow discovery exception where the facts were concealed or otherwise not knowable.
Is a contract to buy goods still eight years in Montana?
No, it is four years under the UCC. A sale of goods is governed by Mont. Code Ann. §30-2-725, a four-year period that accrues at delivery for warranty claims regardless of your knowledge, shorter than the general contract periods.
