Deadline to Sue Over a Contract in Wisconsin
How long you have to sue over a broken written contract in Wisconsin, 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 Wisconsin
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 Wisconsin | What it means |
|---|---|---|
| Standard deadline | 6 years | The general limitations period to file a written-contract claim. |
| Statute | Wis. Stat. §893.43 | The controlling statute for the limitations period. Read the full text through the source link below. |
When it starts
The six years generally runs from when the breach occurs. Wisconsin measures from accrual at breach for ordinary contracts, so if a payment is missed on a due date the clock starts then, not when you later notice the loss.
Discovery rule Yes
Limited. Wisconsin recognizes a discovery rule for some claims, delaying accrual until the injury is discovered or reasonably should have been, but for an ordinary contract the default is accrual at breach. Treat delayed discovery as a fact-specific exception rather than the general rule.
Statute of repose: None
No general statute of repose for ordinary contracts. The six-year period runs from breach or accrual. Improvements to real property carry a separate outer limit under Wis. Stat. §893.89, but that is not the general §893.43 contract clock.
| Deadlines that can differ | Period | What it means |
|---|---|---|
| Oral or unwritten contract | 6 years | Wisconsin does not shorten oral contracts. Section 893.43 covers an action upon any contract, express or implied, so written and oral agreements share the same six-year period and the written-versus-oral gap does not apply here. |
| Sale of goods (UCC) | 6 years | Wisconsin is unusual: its UCC sale-of-goods statute, Wis. Stat. §402.725, uses a six-year period rather than the four years most states apply. It still runs from when the breach occurs, with warranty claims accruing at delivery regardless of your knowledge. |
| Professional services fees | 6 years | Section 893.43 expressly reaches actions to recover fees for professional services, keeping them on the same six-year contract clock. Confirm your claim is a contract action rather than a tort, which may carry a different period. |
What you can do right now
Concrete, neutral steps if a contract was broken in Wisconsin and the clock is running. This is legal information, not legal advice.
- Fix the breach date
Write down when the other side broke the agreement, such as a missed payment due date. In Wisconsin the six years runs from that breach, not from when you later noticed the loss.
- Know that oral and written match
Section 893.43 gives written and oral contracts the same six years, so you are not racing a shorter oral deadline. Still confirm your claim is a contract action rather than a tort.
- If goods were sold, note the six-year UCC clock
Unlike most states, Wisconsin gives sale-of-goods claims six years under Wis. Stat. §402.725, not four. Confirm whether your deal is a sale of goods and count six years from the breach.
- Talk to a Wisconsin attorney before the deadline
Whether §893.43 or another statute governs, and when your claim accrued, turn on your facts. A licensed Wisconsin attorney can confirm your exact deadline before the six 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 Wisconsin contract claimants get wrong
Wisconsin keeps its contract deadline unusually even, and the wrinkles are not where most people look. Section 893.43 gives you six years for an action upon any contract, express or implied, so written and oral agreements carry the same period and the written-versus-oral trap that catches Californians does not exist here. The clock runs from when the cause of action accrues, generally the date of the breach, such as a payment missed on its due date, not the day you later noticed the loss. The real surprise sits in the sale-of-goods rule: while nearly every state caps UCC claims at four years, Wisconsin gives them six under §402.725, so a goods dispute here lasts longer than you might expect. Wisconsin recognizes a discovery rule for some claims, but for an ordinary contract the default is accrual at breach. If a breach is aging toward six years, treat the deadline as firm and confirm which statute governs.
Common questions
What is the statute of limitations on a written contract in Wisconsin?
Six years from the breach, under Wis. Stat. §893.43, for an action upon any contract, express or implied. The clock generally runs from when the contract was broken, not from when you discovered it.
Is an oral contract the same deadline as a written one in Wisconsin?
Yes. Section 893.43 covers any contract, express or implied, so oral and written agreements share the same six-year period. Wisconsin does not impose the shorter oral deadline many other states use.
When does the six-year clock start in Wisconsin?
Generally at the breach, such as a payment missed on its due date. Wisconsin recognizes a discovery rule for some claims, but for an ordinary contract the default is accrual at breach.
Is a contract to buy goods four years in Wisconsin?
No. Wisconsin is unusual: its UCC sale-of-goods statute, Wis. Stat. §402.725, uses a six-year period rather than the four years most states apply. It still accrues at delivery for warranty claims.
