Who has the power to call one
The power to call a special meeting comes from the governing documents and the state statute behind them. In many corporations the board can call one, while shareholders' power depends on the charter, the bylaws, and the state statute, which in some states gives them a limited right of their own. LLC operating agreements, nonprofit bylaws, and co-op or condominium documents each set their own rules, and they are frequently less clear than corporate documents. When a meeting is called by someone without authority, or for a purpose the documents do not allow, the actions taken at it may be open to challenge. Read the documents themselves, including amendments, rather than relying on how meetings have always been run.
Notice, record dates, and permitted business
Special meetings usually require written notice stating the purpose, and the business conducted is typically limited to what that notice describes. A record date fixes who is entitled to vote, and quorum rules decide whether the meeting can act at all. Proxies, remote attendance, and voting procedures are common sources of disputes, especially in closely held companies and residential buildings where tensions are personal. Keep the notice, the mailing or email records showing when it went out, the list of owners entitled to vote, and the minutes or any recording of the meeting itself.
Planning or challenging a meeting
If you are planning a special meeting, we check authority, notice, and quorum before the notice goes out, because mistakes at that stage are hard to fix later. If you believe a meeting was improperly called or conducted, there may be ways to ask a court to review the results, and delay can weaken those challenges. In a first conversation, we look at the governing documents, what was decided, and what you are trying to accomplish, whether that is stopping a vote, redoing it properly, or negotiating with the other side before a court gets involved. Bring the documents and the notice with you, along with any correspondence among owners or board members.
