The statute of limitations for most personal injury lawsuits in New Jersey is two years from the date of the accident that caused your injuries. That two-year limitations period may be extended under several sets of special circumstances. For example, in a medical malpractice personal injury lawsuit, the statute of limitations may not begin to run until the date that you discovered (or should have discovered) that the malpractice occurred. For minors, the limitations period may not begin to arise until the minor reaches age 18.
