(a) In this section, “appraised value” means the appraised value according to the most recent appraisal roll approved by the appraisal review board.
(b) This section may be invoked and used by one or more taxing units if there are delinquent taxes, penalties, interest, and attorney’s fees owing to a taxing unit on a parcel of real property, and:
(1) the total amount of delinquent taxes, penalties, interest, and attorney’s fees owed exceeds the appraised value of the parcel; or
(2) there are 10 or more years for which delinquent taxes are owed on the parcel.

(c) One or more taxing units may file a single petition for foreclosure under this section that includes multiple parcels of property and multiple owners. Alternatively, separate petitions may be filed and docketed separately for each parcel of property. Another taxing unit with a tax claim against the same parcel may intervene in an action for the purpose of establishing and foreclosing its tax lien without further notice to a defendant. The petition must be filed in the county in which the tax was imposed and is sufficient if it is in substantially the form prescribed by § 33.43 and further alleges that:
(1) the amount owed in delinquent taxes, penalties, interest, and attorney’s fees exceeds the appraised value of the parcel; or
(2) there are 10 or more years for which delinquent taxes are owed on the parcel.
(d) Simultaneously with the filing of the petition under this section, a taxing unit shall also file a motion with the court seeking an order approving notice of the petition to each defendant by certified mail in lieu of citation and, if the amount of delinquent taxes, penalties, interest, and attorney’s fees alleged to be owed exceeds the appraised value of the parcel, waiving the appointment of an attorney ad litem. The motion must be supported by certified copies of tax records that show the tax years for which delinquent taxes are owed, the amounts of delinquent taxes, penalties, interest, and attorney’s fees, and, if appropriate, the appraised value of the parcel.
(e) The court shall approve a motion under Subsection (d) if the documents in support of the motion show that:
(1) the amount of delinquent taxes, penalties, interest, and attorney’s fees that are owed exceeds the appraised value of the parcel; or
(2) there are 10 or more years for which delinquent taxes are owed on the parcel.
(f) Before filing a petition under this section, or as soon afterwards as practicable, the taxing unit or its attorney shall determine the address of each owner of a property interest in the parcel for the purpose of providing notice of the pending petition. If the title search, the taxing unit’s tax records, and the appraisal district records do not disclose an address of a person with a property interest, consulting the following sources of information is to be considered a reasonable effort by the taxing unit or its attorney to determine the address of a person with a property interest in the parcel subject to foreclosure:
(1) telephone directories, electronic or otherwise, that cover:
(A) the area of any last known address for the person; and
(B) the county in which the parcel is located;
(2) voter registration records in the county in which the parcel is located; and
(3) where applicable, assumed name records maintained by the county clerk of the county in which the parcel is located and corporate records maintained by the secretary of state.
(g) Not later than the 45th day before the date on which a hearing on the merits on a taxing unit’s petition is scheduled, the taxing unit or its attorney shall send a copy of the petition and a notice by certified mail to each person whose address is determined under Subsection (f), informing the person of the pending foreclosure action and the scheduled hearing. A copy of each notice shall be filed with the clerk of the court together with an affidavit by the tax collector or by the taxing unit’s attorney attesting to the fact and date of mailing of the notice.
(h) In addition to the notice required by Subsection (g), the taxing unit shall provide notice by publication and by posting to all persons with a property interest in the parcel subject to foreclosure. The notice shall be published in the English language once a week for two weeks in a newspaper that is published in the county in which the parcel is located and that has been in general circulation for at least one year immediately before the date of the first publication, with the first publication to be not less than the 45th day before the date on which the taxing unit’s petition is scheduled to be heard. When returned and filed in the trial court, an affidavit of the editor or publisher of the newspaper attesting to the date of publication, together with a printed copy of the notice as published, is sufficient proof of publication under this subsection. If a newspaper is not published in the county in which the parcel is located, publication in an otherwise qualifying newspaper published in an adjoining county is sufficient. The maximum fee for publishing the citation shall be the lowest published word or line rate of that newspaper for classified advertising. The notice by posting shall be in the English language and given by posting a copy of the notice at the courthouse door of the county in which the foreclosure is pending not less than the 45th day before the date on which the taxing unit’s petition is scheduled to be heard. Proof of the posting of the notice shall be made by affidavit of the attorney for the taxing unit, or of the person posting it. If the publication of the notice cannot be had for the maximum fee established in this subsection, and that fact is supported by the affidavit of the attorney for the taxing unit, the notice by posting under this subsection is sufficient.
(i) The notice required by Subsections (g) and (h) must include:
(1) a statement that foreclosure proceedings have been commenced and the date the petition was filed;
(2) a legal description, tax account number, and, if known, a street address for the parcel in which the addressee owns a property interest;
(3) the name of the person to whom the notice is addressed and the name of each other person who, according to the title search, has an interest in the parcel in which the addressee owns a property interest;
(4) the date, time, and place of the scheduled hearing on the petition;
(5) a statement that the recipient of the notice may lose whatever property interest the recipient owns in the parcel as a result of the hearing and any subsequent tax sale;
(6) a statement explaining how a person may contest the taxing unit’s petition as provided by Subsection (j) and that a person’s interest in the parcel may be preserved by paying all delinquent taxes, penalties, interest, attorney’s fees, and court costs before the date of the scheduled hearing on the petition;
(7) the name, address, and telephone number of the taxing unit and the taxing unit’s attorney of record; and
(8) the name of each other taxing unit that imposes taxes on the parcel, together with a notice that any taxing unit may intervene without further notice and set up its claims for delinquent taxes.
(j) A person claiming a property interest in a parcel subject to foreclosure may contest a taxing unit’s petition by filing with the clerk of the court a written response to the petition not later than the seventh day before the date scheduled for hearing on the petition and specifying in the response any affirmative defense of the person. A copy of the response must be served on the taxing unit’s attorney of record in the manner required by Rule 21a, Texas Rules of Civil Procedure. The taxing unit is entitled on request to a continuance of the hearing if a written response filed to a notice of the hearing contains an affirmative defense or requests affirmative relief against the taxing unit.
(k) Before entry of a judgment under this section, a taxing unit may remove a parcel erroneously included in the petition and may take a voluntary nonsuit as to one or more parcels of property without prejudicing its action against the remaining parcels.
(l) If before the hearing on a taxing unit’s petition the taxing unit discovers a deficiency in the provision of notice under this section, the taxing unit shall take reasonable steps in good faith to correct the deficiency before the hearing. A notice provided by Subsections (g)-(i) is in lieu of citation issued and served under Rule 117a, Texas Rules of Civil Procedure. Regardless of the manner in which notice under this section is given, an attorney ad litem may not be appointed for a person with an interest in a parcel with delinquent taxes, penalties, interest, and attorney’s fees against the parcel in an amount that exceeds the parcel’s appraised value. To the extent of any additional conflict between this section and the Texas Rules of Civil Procedure, this section controls. Except as otherwise provided by this section, a suit brought under this section is governed generally by the Texas Rules of Civil Procedure and by Subchapters C and D of this chapter.
(m) A judgment in favor of a taxing unit under this section must be only for foreclosure of the tax lien against the parcel. The judgment may not include a personal judgment against any person.
(n) A person is considered to have been provided sufficient notice of foreclosure and opportunity to be heard for purposes of a proceeding under this section if the taxing unit follows the procedures required by this section for notice by certified mail or by publication and posting or if one or more of the following apply:
(1) the person had constructive notice of the hearing on the merits by acquiring an interest in the parcel after the date of the filing of the taxing unit’s petition;
(2) the person appeared at the hearing on the taxing unit’s petition or filed a responsive pleading or other communication with the clerk of the court before the date of the hearing; or
(3) before the hearing on the taxing unit’s petition, the person had actual notice of the hearing.
