35 Miss. Code R. § 1-08-201
Payment of fines and other assessments within the municipal court system are due at the time assessed. If the individual cannot pay at that time, a record of the assessment should be made. The record should contain the date of the assessment, the reason for the assessment, the amount of the assessment, any amount paid against the assessment, and the name, address and phone number of the person assessed. After thirty (30) days, if payment has not been received, a letter requesting payment should be mailed to the last known address. If payment is not received after an additional thirty (30) days, a phone call should be made. These fines and other assessments are determined to be delinquent after ninety (90) days and may be turned over to a private attorney or private collection agency or agent.
