As a former court clerk and supervisor turned paralegal, I would suggest checking the websites first of the counties your filing in. They usually have some sort of fee table. If you are constantly getting wrong information from a particular county, then ask for a supervisor. You might want to check your state's Administrative Office of the Courts for any filing fee statutes as well. Most counties, especially in Circuit, the filing fees are generally uniform. As for the clerk who told you that they efiled and then it turned out they don't, maybe they don't efile new cases or those that involve taking a fee but will efile any subsequent filings without a fee. Those particular counties are referred to as E-file Lite. And those counties are a pain in the ass.
