If the defendant fails to make an installment payment when due, he/she must be given an opportunity to be heard as to the refusal or neglect to pay the installment when due. If no satisfactory explanation is given at the hearing on failure to pay, the defendant may then be incarcerated. If a defendant has the ability to pay but due to exigent circumstances or misfortune fails to make payment of a particular installment when due, he/she may be given further opportunity to satisfy the fine and/or costs, at the discretion of the court, to be governed by the facts and circumstances of each particular case.
