CJA 20/30 Voucher is a legal document created to provide payment to court appointed attorneys for their services. The voucher is issued by the United States Courts, and is used to compensate attorneys who have been appointed to represent criminal defendants, witnesses, or litigants in civil cases that are funded by the federal government. A CJA 20/30 Voucher is typically issued in two types: a CJA 20 Voucher and a CJA 30 Voucher. A CJA 20 Voucher is used to compensate attorneys for services rendered in a criminal case. This includes services such as pre-trial preparation, trial, and post-trial proceedings. A CJA 20 Voucher is usually issued to attorneys who are appointed to represent defendants who have been charged with federal offenses. A CJA 30 Voucher is used to compensate attorneys for services rendered in a civil case. This includes services such as pre-trial preparation, trial, and post-trial proceedings. A CJA 30 Voucher is usually issued to attorneys who are appointed to represent litigants in civil cases that are funded by the federal government. Both types of CJA 20/30 Vouchers are created with similar language, but provide different amounts of compensation based on the type of case. In order to create a CJA 20/30 Voucher, a judge must sign and approve the voucher, and the U.S. Courts must issue the voucher. The voucher must include the name of the judge, the case number, the amount of compensation, and the date on which the voucher was issued.
