What is a quorum?
Updated September 2026
A quorum is the minimum number of board members who must be present for the meeting's decisions to count. Without it, you can talk, but you cannot do official business.
Your bylaws set the number, usually a majority of directors. State law sets a default and sometimes a floor where bylaws are silent. Meet without a quorum and any business you approve is not valid board action, which is exactly the kind of defect that surfaces later, at the worst time.
Where the number comes from
Your bylaws, first
Look for a section named quorum. One common rule is a majority of directors then in office, and under it a 9-seat board with 2 vacancies needs a majority of the 7 serving. Read the exact wording first. The other rule is common too. California and some others count a majority of the authorized seats, which makes that same board need 5, not 4.
State law, underneath
Nearly every state's nonprofit statute supplies a default quorum where bylaws are silent, and many set a floor bylaws cannot go below. The common floor is one third of the directors in office; California sets its own, not less than one fifth of the authorized number and never fewer than two. If your bylaws are silent or ancient, this is the reading assignment.
What happens without one
You may still gather, hear reports, and discuss. You may also end the meeting, set a time to meet again, take a short break, or try to reach missing members. Anything else you decide is not valid board action. Get casual about it and you build a record of decisions that do not legally exist: budgets never adopted, officers never elected. An auditor, a bank, or a lawyer will ask for the minutes one day.
What follows from that varies more than most guides admit. Some states treat the action as void, some as voidable until someone challenges it, and several have a statutory cure for defective corporate acts. A third party who already relied on the decision may be protected either way. If something consequential was decided without a quorum, that is a question for a lawyer in your state, not a question for a checklist.
If quorum is a constant struggle
Check whether remote attendance counts
Most people have this backwards. In most states directors may join remotely unless your articles or bylaws say they cannot. The test is that everyone can hear each other at the same time. So the job is usually not to add permission. It is to check that old bylaws did not remove it. A few states differ, so read both.
Right-size the board
A 15-seat board that can never seat 8 is really a 9-member board wearing a bigger number. Amend to the board you actually have.
Deal with ghosts
Members who never attend still raise the bar if they still serve. Term limits and an attendance expectation in the bylaws are the polite fix.
Record the count every meeting
One line in the minutes: members present, quorum met. It is the cheapest protection a board can give itself.
This is general information, not legal or tax advice. Board rules vary by state, and so does what your bylaws can say. Tax questions turn on your own facts. Read your bylaws and your state's nonprofit act, and ask an attorney or CPA before you rely on any of it.
Quorum is one of 41 terms in our plain-English nonprofit glossary.
