Whenever the time of payment of any assessment, installment or portion thereof has been extended as provided in this Article and the extended assessment or installment includes an assessment, installment or portion thereof which is past due and has been certified to the County Collector as delinquent, or the delinquent property has been forfeited to the State for the non-payment of such assessment, installment or portion, the court shall, in its order extending the time of payment, direct that such tract be removed from the delinquent list or direct that such tract be released from such judgment and forfeiture by proper entry upon the tax sale, judgment and forfeiture record of the county in which the land is situated, without charge to the district or the bondholders.
Where the amount of the assessment to be withdrawn from the delinquent list or to be released from the tax sale, judgment and forfeiture record is less than the whole amount of the assessment or installment for which the property has been certified delinquent or forfeited, only that portion of the assessment or installment the time of payment of which has been extended shall be so released or withdrawn, and in withdrawing or releasing such land, the records shall clearly indicate that only that portion of the assessment or installment the time of payment of which has been extended has been withdrawn or released. The balance of the assessment or installment shall remain delinquent or forfeited, as the case may be, and be collected in the manner provided by law for the collection of such delinquencies or forfeitures.
