A defendant who has been required to pay a fine or costs, including a requirement to pay fine or costs as a condition of probation, or a prosecutor, may at any time petition the sentencing court for a remission or revocation of the fine or costs or any unpaid portion of it. If it appears to the satisfaction of the court that the circumstances which warranted the imposition of the fine or costs no longer exist, that it would otherwise be unjust to require payment, or that the proper administration of justice requires resolution of the case, the court may remit or revoke the fine or costs or the unpaid portion in whole or in part or may modify the method of payment. (1977, c. 711, s. 1.)
