    Sec. 255. Sales in error.
    (a) When, upon application of the county collector, the owner of the certificate of purchase, or a municipality that owns or has owned the mobile home ordered sold, it appears to the satisfaction of the court that ordered the mobile home sold that any of the following subsections are applicable, the court shall declare the sale to be a sale in error:
        (1) the mobile home was not subject to taxation,
        (1.5) the mobile home has been moved to a different location,
        (2) the taxes had been paid prior to the sale of the mobile home,
        (3) there is a double computation of the tax,
        (4) the description is void for uncertainty,
        (5) the assessor, chief county assessment officer, board of review, board of appeals, or
    
other county official has made an error (other than an error of judgment as to the value of any mobile home),
        (5.5) the owner of the mobile home had tendered timely and full payment to the county
    
collector that the owner reasonably believed was due and owing on the mobile home, and the county collector did not apply the payment to the mobile home; provided that this provision applies only to mobile home owners, not their agents or third-party payors,
        (6) prior to the tax sale a voluntary or involuntary petition has been filed by or
    
against the legal or beneficial owner of the mobile home requesting relief under the provisions of 11 U.S.C. Chapter 7, 11, 12, or 13, or
        (7) the mobile home is owned by the United States, the State of Illinois, a
    
municipality, or a taxing district.
    (b) When, upon application of the owner of the certificate of purchase only, it appears to the satisfaction of the court that ordered the mobile home sold that any of the following subsections are applicable, the court shall declare the sale to be a sale in error:
        (1) A voluntary or involuntary petition under the provisions of 11 U.S.C. Chapter 7, 11,
    
12, or 13 has been filed subsequent to the tax sale and prior to the issuance of the tax certificate of title.
        (2) The mobile home sold has been substantially destroyed or rendered uninhabitable or
    
otherwise unfit for occupancy subsequent to the tax sale and prior to the issuance of the tax certificate of title.
    (c) When the county collector discovers, prior to the expiration of the period of redemption, that a tax sale should not have occurred for one or more of the reasons set forth in subdivision (a)(1), (a)(2), (a)(6), or (a)(7) of this Section, the county collector shall notify the last known owner of the certificate of purchase by certified and regular mail, or other means reasonably calculated to provide actual notice, that the county collector intends to declare an administrative sale in error and of the reasons therefor, including documentation sufficient to establish the reason why the sale should not have occurred. The owner of the certificate of purchase may object in writing within 28 days after the date of the mailing by the county collector. If an objection is filed, the county collector shall not administratively declare a sale in error, but may apply to the circuit court for a sale in error as provided in subsection (a) of this Section. Thirty days following the receipt of notice by the last known owner of the certificate of purchase, or within a reasonable time thereafter, the county collector shall make a written declaration, based upon clear and convincing evidence, that the taxes were sold in error and shall deliver a copy thereof to the county clerk within 30 days after the date the declaration is made for entry in the tax judgment, sale, redemption, and forfeiture record pursuant to subsection (d) of this Section. The county collector shall promptly notify the last known owner of the certificate of purchase of the declaration by regular mail and shall promptly pay the amount of the tax sale, together with interest and costs as provided in Sections 260 through 280, upon surrender of the original certificate of purchase.
    (d) If a sale is declared to be a sale in error, the county clerk shall make entry in the tax judgment, sale, redemption and forfeiture record, that the mobile home was erroneously sold, and the county collector shall, on demand of the owner of the certificate of purchase, refund the amount paid, pay any interest and costs as may be ordered under Sections 260 through 280, and cancel the certificate so far as it relates to the mobile home. The county collector shall deduct from the accounts of the appropriate taxing bodies their pro rata amounts paid.
