Notice requirements for committee meetings ensure minimum notice, attendance options and electronic voting access for creditors. Regulation requires trustees to convene committee meetings on need or creditor request and to serve notice at provided addresses. Notices must give at least seven days' notice, not less than forty-eight hours, state venue, time, date, participation and voting options, and attach an agenda with matters, voting issues and relevant documents. If videoconference or electronic voting is available, the notice must explain procedures, provide login and secure password facilities, and give contact details for related queries.
