Texas Tax Code - TAX § 26.081. Petition Signatures

(a) A voter's signature on a petition filed in connection with an election under this chapter is not required to appear exactly as the voter's name appears on the most recent official list of registered voters for the signature to be valid.

(b) If the governing body reviewing the petition is unable to verify the validity of a particular voter's signature, and the petition does not contain any reasonable means by which they might otherwise do so, such as the voter's registration number, home address, or telephone number, the governing body may then require the organizer of the petition to provide such information for that particular voter if the organizer wishes for the signature to be counted.
