Yes. Every jurisdiction has deadlines for filing lawsuits in court. These can be complex depending on the type of injury, whether it happened to an adult or a child, and whether it was caused by a government employee, corporation, or a private person. That’s one of the reasons why it is important to consult a lawyer soon after you feel you may have a claim. The most basic rule is called the statute of limitations. We have extensive explanations on our website of the legal deadlines for suing in the District of Columbia, Virginia and Maryland. But the best way to know for sure if you can still bring a claim is to get in touch with an attorney who practices in the jurisdiction where it happened.
