In general, the Statute of Limitations in Massachusetts for negligence actions is three years. If the victim is a minor, that Statute of Limitations does not run out until his 21 st birthday.
However, there are some exceptions. If the claim is being made against the Federal Government, Commonwealth of Massachusetts or an organization such as the M.B.T.A., there are shorter time limits. Sometimes, the Statute can be extended if the Defendant concealed the wrong doing or if the relation of the injury to the accident could not reasonably be known to the victim.
