How long do I have to sue over written contract in Massachusetts?
Answered for: Massachusetts
Section 2. Actions of contract, other than those to recover for personal injuries, founded upon contracts or liabilities, express or implied, except actions limited by section one or actions upon judgments or decrees of courts of record of the United States or of this or of any other state of the United States, shall, except as otherwise provided, be commenced only within six years next after the cause of action accrues.
The statute states 6 years for written contract. When that clock starts, and whether it can be paused, are separate questions this entry does not answer.
This answer is true in Massachusetts and nowhere else on this site. Another jurisdiction is another answer, or an honest gap: see what has been read for Massachusetts.
