Mississippi Code Title 99. Criminal Procedure § 99-35-105

Appeals in criminal cases shall not stay the judgment or sentence appealed from unless the appellant shall prepay all of the costs in the lower court, including the cost of preparing the record of the proceedings in the trial court and the fee prescribed in Section 25-7-3, to the clerk of the lower court. If the appellant shall make affidavit that he is unable to prepay the costs, he shall have an appeal without prepayment of costs; and his appeal shall stay the judgment appealed from. It shall be the responsibility of the county in which the conviction was taken to timely prepay all costs when an indigent appellant makes an affidavit that he is unable to make such payments.

It shall be the duty and obligation of the county to reimburse a successful appellant in a criminal case for court costs, including the cost of preparing the record of the proceedings in the trial court.
