If the party is confined in any prison or is in the custody of any civil officer, the court or judge granting the writ shall certify thereon the sum to be paid for the expense of bringing the party from the place where the party is imprisoned or restrained. The officer to whom the same is directed shall not be bound to obey it, unless that sum is paid or tendered to the officer. This section is subject to section 607-3, pursuant to which prepayment of the expense may be waived, or the sum required may be reduced or remitted.
