The time limit a person has to file a lawsuit is determined either by the specific federal law that is at issue or the types of claims raised in the lawsuit. This information is legal advice and the Pro Se Intake Unit cannot tell you how long you may have to file a lawsuit. In order to find out how long you may have to file a case, you must do legal research. Many federal laws specifically state the statute of limitations period. Generally, if the federal law at issue does not include a statute of limitations, you must look to the statute of limitations period listed in state law for the most similar type of claim.
