How long do I have to sue over oral contract in Wisconsin?
Answered for: Wisconsin
an action upon any contract, obligation, or liability, express or implied ... shall be commenced within 6 years after the cause of action accrues or be barred.
In Wisconsin you have 6 years to sue over oral contract. When that clock starts, and whether anything can pause it, are separate questions this entry does not answer.
This answer is true in Wisconsin and nowhere else on this site. Another jurisdiction is another answer, or an honest gap: see what has been read for Wisconsin.
