When the grantee of a tax deed issued pursuant to a sale held on or prior to September 1, 1951, or any one claiming thereunder, has not perfected his title in accordance with Section 13-109 of the Code of Civil Procedure, it is lawful for the owner of the property or his agent or attorney to pay or tender to the tax title holder the moneys expended by the tax title holder upon the sale with 7% interest per year thereon, together with subsequent taxes and special assessments paid and the statutory fees and costs incurred. When the payment or tender is made the tax title holder shall reconvey the property to the owner thereof. The amount of the tender may be based upon an estimate prepared by the county clerk. However, the county clerk is not required to include any subsequent taxes or special assessments in his certificate of redemption, nor shall the payment thereof be a charge upon the property, unless the purchaser, assignee, or holder of the tax certificate has filed with the county clerk, before redemption, an official, original or duplicate tax collector's receipt for the payment of the subsequent taxes or special assessments, and the tax collector shall execute and furnish such duplicate tax receipts.
In preparing the estimates, the county clerk shall include, in addition to the amount of moneys herein provided for, the following fees to the tax title holder:
The county clerk may charge $5 for preparing the estimate which shall be prima facie evidence of the amount due the tax title holder.
