Ala. Code § 12-22-195

The burden shall be upon the convicted defendant or petitioner to satisfy the trial judge that said defendant or petitioner is without said sufficient funds and has no reasonable way to procure the same. If the trial judge is in doubt after such investigation as he deems proper, he shall deny such petition, in whole or in part, and state his reasons therefor and cause the same to be entered on the minutes of the court.
