The members' vote will provide a climax to in-fighting between chairman Angus Johnson's board and a rival ticket featuring AFL legend Leigh Matthews that erupted following coach Michael Voss's sacking two months ago.
The AFL had stepped in to encourage mediation between the warring parties and reportedly presented a proposal for a compromise board on Tuesday.
However, the Lions confirmed an EGM would be called next month after holding a general board meeting on Wednesday.
"The Brisbane Lions board today resolved to convene a general meeting of its members on November 13," a statement said.
"The board met in Brisbane this morning where the date and motions to be put to the general meeting were agreed upon.
"Voting members will receive formal notice of the meeting by post.
"Directors affected by the proposed resolutions will be provided with the opportunity to provide to the club a written statement of up to 1,000 words to be included with the notice of meeting."
Johnson broke his silence when he wrote a letter to members, posted on the Lions website on Tuesday.
He accused Lions directors Mick Power and Paul Williams - part of Matthews' rival ticket, of not acting in the best interests of the club.
"By publicly criticising decisions they made with the rest of the board, they are effectively making a hostile takeover bid for your club," he wrote.
Williams and Power fell out with Johnson over the handling of Voss' sacking and failing to secure former premiership winning Sydney coach Paul Roos as his replacement.
Former premiership winning defender Justin Leppitsch was eventually handed the reins.
He returned from an overseas trip on Tuesday and spoke with Brownlow Medallist Simon Black about his future.
Black is believed to be close to deciding on whether he plays a 17th AFL season.
