The Tennessee Financial Affidavit (CJA-23) is a form used to determine a person's ability to pay court costs and attorney fees. It is used most commonly in criminal cases. This affidavit is required by the Tennessee state courts and must be filled out completely and accurately by the defendant. The information provided on this form is used to determine the defendant's financial status, so the court can make an informed decision about court costs and attorney fees. This form must be signed and notarized by the defendant and submitted to the court. There are two types of Tennessee Financial Affidavit (CJA-23): the CJA-23A and the CJA-23B. The CJA-23A is used for those defendants who are able to pay their own court costs and attorney fees. The CJA-23B is used for those defendants who are not able to pay their own court costs and attorney fees and are seeking a court-appointed attorney.
