Is there a time limit in which you have to make the claim?

It depends on what "happened in 2001 and 2002."  Most cases have statutes of limitations, meaning that you cannot file a lawsuit if it has been over a certain amount of years.  For example, in North Carolina, there is likely a 3 year statute of limitations for medical malpractice claims.  However, some state laws give you additional time if you did not find out about the harm/damage until years later.  However, most are 7 years or 9 years, but each state varies.  If the case involves libel/slander, the statute of limitations is likely 1 year; and if it involves wrongful death, it is likely 2 years. However, some crimes do have extended (or no) statutes of limitations, like sexual assault crimes.  Determining the statute of limitations is very fact dependent and depends on your state laws.  Thus, you may want to consult a local attorney in your area who may handle the type of case you need advice.  I am sorry I am not able to provide you with additional information due the lack of details you provided.  Best of luck.
