Tenn. Code Ann. § 43-38-515: Waiver of notice

(a) A member may waive any notice required by this section. Except as otherwise provided in this section, a waiver of notice by a member entitled to notice is effective, whether given before or after the meeting or other balloting, if notice is given in writing, signed by the member entitled to the notice, and filed with the minutes or corporate records.

(b) A member's attendance at or participation in a meeting waives any required notice to the member of the meeting, unless the member, at the beginning of the meeting or promptly upon the member's arrival, objects to holding the meeting or transacting business at the meeting and does not thereafter vote for or assent to action taken at the meeting. The secretary is required to note the objection in the minutes of the meeting.
