Courts mention (through their websites) the process in which to remove/expunge criminal records. Depending on the county or court venue, it is generally a petition or lawsuit to the court. Misdemeanors are often treated differently from felony convictions. There aren't any guarantees that the petition will be granted, at the least not by the courts. You will usually need legal representation, however, there doesn't seem to be any restrictions against self representation. There are advocate groups or legal services such as the Council on Crime and Justice which will be very helpful, even by simply reading their content they put out for the public.
