Whenever, in a proceeding under Sections 9-2-120 through 9-2-124, the refunding of securities and the extending of the time of payment of any assessment or installments thereof include an assessment or installments past due and the property against which the past due assessment or installments or any part thereof were levied has been sold at a sale of property to enforce the collection of the past due assessment to the municipality levying the assessment and the municipality has not paid the purchase price at that sale and a certificate of purchase has been issued and delivered to the municipality, this past due assessment or installments or any part thereof shall be extended, and the securities issued to anticipate their collection shall be refunded, as in the case of an assessment returned delinquent, withdrawn, or forfeited, and the lien of the original assessment and of the certificate of purchase shall be continued and preserved by the assessment as extended.
In such a case the court in which the proceeding is pending, in the order extending the time of payment and authorizing the refunding of the securities, shall order the municipality levying the assessment to present its certificate of purchase to the county clerk. The county clerk shall cancel this certificate by endorsing thereon the words "cancelled by assessment as extended" and shall enter a note of such cancellation upon his tax, judgment, sale redemption, and forfeiture record. Where this certificate or evidence thereof has been recorded with the recorder of deeds or registered with the registrar of titles the court shall order the county clerk to issue a certificate to the municipality showing the legal description of all lots, blocks, tracts, and parcels of land against which a certificate or evidence thereof has been recorded or registered and reciting the cancellation of the certificate of purchase by virtue of the extension of the assessment and refunding of the securities. This certificate shall be filed by the municipality with the recorder or the registrar of titles, as the case may be. Thereupon the lien of that assessment as extended shall stand in lieu of the lien of the original assessment and of the certificate of purchase, and the assessment as extended shall be collected in the same manner as the original assessment.
The county clerk shall receive for his services rendered as set forth in this section a fee of 35 cents for each certificate so cancelled. This fee, together with the fees of the recorder and of the registrar of titles shall be paid by the security holders.
