S.C. Code § 17-25-350
In any offense carrying a fine or imprisonment, the judge or magistrate hearing the case shall, upon a decision of guilty of the accused being determined and it being established that he is indigent at that time, set up a reasonable payment schedule for the payment of such fine, taking into consideration the income, dependents and necessities of life of the individual. Such payments shall be made to the magistrate or clerk of court as the case may be until such fine is paid in full. Failure to comply with the payment schedule shall constitute contempt of court; however, imprisonment for contempt may not exceed the amount of time of the original sentence, and where part of the fine has been paid the imprisonment cannot exceed the remaining pro rata portion of the sentence.
No person found to be indigent shall be imprisoned because of inability to pay the fine in full at the time of conviction.
Entitlement to free counsel shall not be determinative as to defendant's indigency.
