Sec. 21-310. Sales in error.

(a) When, upon application of the county collector, the owner of the certificate of purchase, the holder of a 5% lien issued pursuant to Section 21-240, or a municipality which owns or has owned the property ordered sold, it appears to the satisfaction of the court which ordered the property sold that any of the following subsections are applicable, the court shall declare the sale to be a sale in error:

(1) the property was not subject to taxation, or all or any part of the lien of taxes sold has become null and void pursuant to Section 21-95 or unenforceable pursuant to subsection (c) of Section 18-250 or subsection (b) of Section 22-40;

(2) the taxes or special assessments had been paid prior to the sale of the property;

(3) there is a double assessment;

(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 material to the tax certificate at issue (other than an error of judgment as to the value of any property), provided, however, that a sale in error may not be declared upon application of the owner of the certificate of purchase under this paragraph (5) if the county collector provided notice in accordance with Section 21-118 that the same property received a previous sale in error on the same facts;

(5.5) the owner of the homestead property had tendered timely and full payment to the county collector that the owner reasonably believed was due and owing on the homestead property, and the county collector did not apply the payment to the homestead property; provided that this provision applies only to homeowners, not their agents or third-party payors;

(6) a voluntary or involuntary petition was filed by or against the legal or beneficial owner of the property requesting relief under the provisions of 11 U.S.C. Chapter 7, 11, 12, or 13, and the bankruptcy case was open on the date the collector's application for judgment was filed pursuant to Section 21-150 or 21-155 or the date of the tax sale;

(7) the property is owned by the United States, the State of Illinois, a municipality, or a taxing district; or

(8) the owner of the property is a reservist or guardsperson who is granted an extension of his or her due date under Sections 21-15, 21-20, and 21-25 of this Act.

(b) When, upon application of the owner of the certificate of purchase only, it appears to the satisfaction of the court which ordered the property 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 deed, and the bankruptcy case was open on the date the petition for a sale in error was filed.

(2) The improvements upon the property sold have been substantially destroyed subsequent to the tax sale and prior to the issuance of the tax deed; however, if the court declares a sale in error under this paragraph (2), the court may order the holder of the certificate of purchase to assign the certificate to the county collector if requested by the county collector. The county collector may, upon request of the county, as trustee, or upon request of a taxing district having an interest in the taxes sold, further assign any certificate of purchase received pursuant to this paragraph (2) to the county acting as trustee for taxing districts pursuant to Section 21-90 of this Code or to the taxing district having an interest in the taxes sold.

(3) There is an interest held by the United States in the property sold which could not be extinguished by the tax deed.

(4) The real property contains a hazardous substance, hazardous waste, or underground storage tank that would require cleanup or other removal under any federal, State, or local law, ordinance, or regulation, only if the tax purchaser purchased the property without actual knowledge of the hazardous substance, hazardous waste, or underground storage tank. The presence of a grease trap on the property is not grounds for a sale in error under this paragraph (4). This paragraph (4) applies only if the owner of the certificate of purchase has made application for a sale in error at any time before the issuance of a tax deed. If the court declares a sale in error under this paragraph (4), the court may order the holder of the certificate of purchase to assign the certificate to the county collector if requested by the county collector. The county collector may, upon request of the county, as trustee, or upon request of a taxing district having an interest in the taxes sold, further assign any certificate of purchase received pursuant to this paragraph (4) to the county acting as trustee for taxing districts pursuant to Section 21-90 of this Code or to the taxing district having an interest in the taxes sold.

(5) The certificate of purchase was issued prior to the effective date of this amendatory Act of the 104th General Assembly, the certificate's redemption period has expired, and the certificate has not been deeded, redeemed, vacated, or voided under Section 22-85.

Whenever a court declares a sale in error under this subsection (b), the State's attorney shall promptly notify the county collector in writing.

(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)(3), (a)(4), (a)(5.5), (a)(6), (a)(7), or (a)(8) of this Section, the county collector shall notify the last known owner of the tax certificate 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, except if the certificate was issued pursuant to a no-cash bid, promptly pay the amount of the tax sale, together with interest and costs as provided in Section 21-315, upon surrender of the original certificate of purchase.

(c-5) When the holder of the certificate of purchase is the county as trustee for taxing districts, upon request of or consent by the county as trustee, or its agent, if the county collector agrees, prior to the issuance of a tax deed, that a tax sale should not have occurred for one or more of the reasons set forth in subdivision (a)(1), (a)(2), (a)(3), (a)(4), (a)(5.5), (a)(6), (a)(7), (a)(8), or (b)(1) of this Section, or, with the consent of the chief county assessment officer, subdivision (a)(5), the county collector may declare an administrative sale in error. Such declaration shall be a written declaration, based on clear and convincing evidence, that the taxes were sold in error and the county collector shall deliver a copy thereto 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.

(d) If a sale is declared to be a sale in error for any reason set forth in Section 22-35, Section 22-50, or subdivision (a)(5), (b)(2), or (b)(4) of this Section, the tax certificate shall be forfeited to the county as trustee pursuant to Section 21-90 of this Code, unless the county collector informs the county and the county clerk in writing that the tax certificate shall not be forfeited to the county as trustee. The county clerk shall make entry in the tax judgment, sale, redemption and forfeiture record, that the property was erroneously sold and that the tax certificate is forfeited to the county pursuant to Section 21-90, and the county collector shall, on demand of the owner of the certificate of purchase, refund the amount paid, except for the nonrefundable $80 fee paid, pursuant to Section 21-295, for each item purchased at the tax sale, pay any interest and costs as may be ordered under Sections 21-315 through 21-335, and cancel the certificate so far as it relates to the property. The county collector shall deduct from the accounts of the appropriate taxing bodies their pro rata amounts paid.

(e) Whenever the collector declares an administrative sale in error under this Section, the collector must send a copy of the declaration of the administrative sale in error, and documentation sufficient to establish the reason why the sale should not have occurred, to the government entity responsible for maintaining assessment books and property record cards for the subject property. That entity must review the documentation sent by the collector, make a determination as to whether an update to the assessment books or property record cards is necessary to prevent a recurrence of the sale in error, and update the assessment books or property record cards as appropriate.

(f) Whenever a court declares a sale in error under this Section, the State's attorney must send a copy of the application and order declaring the sale in error to the county collector, the county clerk, and the government entity responsible for maintaining the assessment books and property record cards for the subject property. The collector, the county clerk, and the other government entity must each review the application and order sent by the State's attorney and make a determination as to whether an update to its respective records is necessary to prevent a recurrence of the sale in error, and update its records as appropriate.

The changes made to this Section by this amendatory Act of the 103rd General Assembly apply to matters concerning tax certificates issued on or after the effective date of this amendatory Act of the 103rd General Assembly.
