Tex. Property Code § 221.089

(a) A meeting of the members of the association must be held annually after the termination of the period of developer control under Section 221.083. Special meetings of the members of the association may be called by the president, by a majority of the board, or by owners having at least 25 percent of the votes allocated to timeshare interests in the association or any lower percentage specified in the project instrument.

(b) Unless the project instrument provides otherwise, the association or managing entity must send notice of the meeting to the mailing address of each owner on record with the association:

(1) not later than the 30th day or earlier than the 90th day before the date of an annual meeting; and

(2) not later than the 10th day or earlier than the 60th day before the date of a special meeting.

(c) The notice of a meeting of the owners must state the date, time, and place of the meeting. The notice of a special meeting of the owners must also state the purpose of the meeting. A notice of a meeting may be included in a list of upcoming meetings sent to owners, and the list is not required to be specific to one meeting. The failure of an owner to receive actual notice of a meeting of the owners does not affect the validity of any action taken at that meeting.

(d) Unless the project instrument provides otherwise, the association or managing entity must send notice of a board meeting held after the date the developer control period terminates to the mailing address of each owner on record with the association not later than the 10th day before the date of the meeting. Notice to owners of a board meeting is not required if emergency circumstances require action by the board before notice can be given. A notice of a board meeting must state the date, time, and place of the meeting. A notice of a meeting may be included in a list of upcoming meetings sent to owners, and the list is not required to be specific to one meeting. The failure of an owner to receive actual notice of a board meeting does not affect the validity of any action taken at that meeting.

(e) A notice may be provided in a newsletter or a similar mailing. Notice may be provided by prepaid United States mail, e-mail for those owners who have provided an e-mail address, or any other reasonable method selected by the board.

(f) Notwithstanding Subsections (a)-(d) or any other law related to notice by an association, a notice to an owner may be provided by conspicuous disclosure on the association's website if the owner has consented to that alternative notice. Consent to that alternative notice must be in writing and may be revoked by the owner at any time.

(g) An affidavit of notice by an officer of the association or the managing entity is prima facie evidence that notice was provided under this section.
