(a) Except as otherwise provided by existing court order, law, or other comptroller rule, a property owner shall use comptroller form 50-162 to designate an agent for property tax matters pursuant to Tax Code, §1.111(a). Except as provided in subsection (b) of this section, forms required to be used by this section shall be used as adopted by the comptroller, without changes in form or substance including, but not limited to, content, font size, and pagination. For the purposes of this section, the term "property owner" includes a person who claims a legal interest in the property.
(b) All appraisal districts shall prepare and make available copies of comptroller form 50-162 for property owners to use in designating agents for property tax matters. An appraisal district may pre-print the appraisal district's name and address in the spaces designated for such information on form 50-162; however, no other changes or modifications may be made. An appraisal district may, if approved in advance in writing by the comptroller, make non-substantive modifications to form 50-162 for purposes of facilitating electronic delivery.
(c) Designation of an agent to receive notices or other communications is not effective for any notice or other communication about a property that is mailed or sent by electronic means before the property owner's written notice is filed with the appraisal district in accordance with Tax Code, §1.111(f). A written statement filed pursuant to Tax Code, §1.111(j) is not effective for any notice or other communication about a property that is mailed or sent by electronic means before the written statement is filed with the protest in accordance with Tax Code, §1.111(j). No written designation or request for delivery of tax bills pursuant to Tax Code, §1.111(f) is required for a mortgage lender who is authorized by a deed of trust executed by the property owner to pay taxes on the property.
(d) For the purposes of the prohibition against designating more than one agent for a single item of property in Tax Code, §1.111(d), an item of property means the property included under a single appraisal district account number. Unless the appraisal district has separately listed an improvement or the property owner presents documentation to the appraisal district showing separate ownership of land and improvements, a property owner may not designate separate agents to represent land and improvements. A property owner may, however, designate a different agent for purposes of Tax Code, Chapter 41A, or any other matter as provided by law or other comptroller rule.
(e) If a property owner directs delivery of tax bills or notices to an agent after the date appraisal records are certified, the chief appraiser, as soon as practicable after the designation is filed, shall notify the affected taxing unit of the property owner's name, the account number of the property, and the name and address of the agent designated for notice.
(f) A property owner is not required to file a written designation of agent for a person who:
  (1) acts as a courier for the property owner;
  (2) prepares documents in a clerical capacity for the property owner;
  (3) is an employee of the owner or of a corporate parent, affiliate, or subsidiary of the owner and is authorized by the owner to represent him; or
  (4) is an attorney licensed to practice law in the State of Texas and retained by a property owner to represent him before the appraisal district or appraisal review board.
(g) A person who owns property in more than one county may file a reproduction of the original signed appointment form with each appraisal district. If the chief appraiser has reason to question the authenticity of the document, the chief appraiser may require the property owner or the agent to provide the original for inspection.
(h) Forms adopted by reference. The Comptroller of Public Accounts adopts by reference Appointment of Agent for Property Tax Matters (Form 50-162) and, for purposes of use as required by court order existing as of the date of amendment of this section, Appointment of Agent for Single-Family Residential Property Tax Matters (Form 50-241).
