In a California for-profit corporation, a quorum is a majority of the authorized directors for board meetings and a majority of the shares entitled to vote for shareholder meetings. Your bylaws can lower those numbers, but only to a statutory floor: one-third of the shares for shareholders, and for directors the larger of one-third of the authorized number or two. Nonprofits follow different numbers. This guide explains each rule, shows how to write the bylaw clause, and covers the mistakes that make votes challengeable.
TL;DR
- Default board quorum: a majority of the authorized number of directors (Corporations Code § 307). Bylaws can go lower, but never below the larger of one-third of authorized directors or two.
- Default shareholder quorum: a majority of shares entitled to vote (§ 602). The floor is one-third of those shares.
- Nonprofit public benefit corporations use § 7211: a majority by default, with a floor of the larger of one-fifth of authorized directors or two.
- Quorum is counted against the authorized number of directors, not the number of seats currently filled.
- Write the number into your bylaws and record who attended in every set of minutes.

What a quorum is and why it matters
A quorum is the minimum number of people who must be present for a meeting to conduct valid business. Without it, a vote can be challenged later: by a minority shareholder, a departing co-founder, a lender doing diligence, or a buyer's attorney.
For small California corporations the risk is rarely dramatic. It is usually quiet. Two of three directors sign off on a stock issuance, nobody notes who attended, and three years later a new investor asks for proof the board acted properly. The minutes are the proof, and the bylaws quorum clause is the standard the minutes are measured against. If you are still sorting out what belongs where, our piece on bylaws versus minutes in California draws the line.
Board quorum under Corporations Code § 307
Section 307 is the starting point for a standard for-profit corporation. The statute sets a majority of the authorized number of directors as the default quorum. The articles or bylaws can set a different number, with a floor: not less than the larger of one-third of the authorized number of directors or two. If the corporation is authorized to have only one director, one director is enough.
Authorized, not currently serving
The count runs against the authorized number stated in your bylaws or articles. If your bylaws authorize five directors and two seats are vacant, a majority quorum is still three, not two. This trips up many small boards. If you want flexibility, set a range or a fixed number you can actually staff, and keep it current.
A quick table for common board sizes
Using the § 307 rules, here is the default and the lowest quorum your bylaws could set:
| Authorized directors | Default quorum (majority) | Lowest quorum bylaws may set |
|---|---|---|
| 1 | 1 | 1 |
| 2 | 2 | 2 |
| 3 | 2 | 2 |
| 5 | 3 | 2 |
| 7 | 4 | 3 |
| 9 | 5 | 3 |
The last column is the larger of two and one-third of the authorized number, rounded up so the fraction is met. Check the arithmetic against the statute text before you commit a number to your bylaws, and have a California attorney confirm the wording if you have investors or a board with divided interests.
Adjourning when quorum fails
Section 307 also provides that a majority of the directors present, whether or not a quorum is present, may adjourn a meeting to another time and place. That is the rescue move. If three of five directors were expected and only two show up, they cannot approve anything, but they can adjourn and reconvene. Practitioners treat adjournment as the key tool for failed quorums, and the rules for reconvening differ among for-profit corporations, nonprofits and common interest developments.
Write the adjournment in the minutes: who attended, that quorum was not met, and the new date and time. For the full directors' checklist, see our directors' quorum checklist for §307 and §602.
Shareholder quorum under § 602
For shareholder meetings, Section 602 says that unless the articles provide otherwise, a majority of the shares entitled to vote, represented in person or by proxy, is a quorum. The articles can provide for a lesser quorum, but not less than one-third of the shares entitled to vote. A Loeb & Loeb summary of California corporation law.pdf?hash=37649ABF78664582345BB04D63747820&rev=59626ad3b9b34589bf85fef7bc68b2f1) describes the same structure.
A few practical points:
- Proxies count. A shareholder who gives a valid proxy is present for quorum purposes.
- Shares, not people. One founder holding 80 percent of the shares can constitute a quorum alone. Five minority holders with 20 percent cannot.
- Entitled to vote matters. Shares that cannot vote on the matter do not count toward the denominator.
- Higher quorums are limited. The research we checked indicates that a quorum above a majority is generally not available unless the entity is a close corporation.
We go deeper on this in California shareholder meeting quorum: the § 602 rule.
Where does the number live: articles or bylaws?
The text of § 602 refers to the articles for a different quorum, and § 307 refers to the articles or the bylaws for directors. Because the statute language differs, a shareholder quorum below a majority is safest when it appears in the articles of incorporation, and often also repeated in the bylaws for readability. A lower shareholder quorum placed only in the bylaws is a drafting risk you do not need to take. If you are unsure, ask a California business attorney.
Withdrawals after the meeting starts
A common belief is that quorum must hold from the opening gavel to the last vote. Under the California statutes, once a quorum is initially present, the meeting can continue to transact business even if people leave, as long as each action is approved by at least a majority of the required quorum. The research we have lists this under § 602 for shareholders, and § 307 uses comparable language for directors.
Example: a seven-director board has a majority quorum of four. All seven attend, three leave early, and four remain. A vote needing a majority of the required quorum needs three yes votes. Two yes votes from the four remaining would not be enough, even though the four remaining are still a majority of the original quorum.
Still, do not lean on this. If someone walks out to block action, record the time they left and the vote count for each item. Clean minutes are the best defense.
Nonprofits are different
If you formed a nonprofit public benefit corporation, § 7211 governs. The statute sets a majority of authorized directors as the quorum, and bylaws cannot set it below the larger of one-fifth of the authorized directors or two, unless the board is authorized to have only one director. That floor is lower than the for-profit one.
A mutual benefit corporation such as a membership association has a different member default. One HOA-focused guide reports a default of one-third of the voting power for members, which the bylaws may change. Common interest developments have their own reconvening rules; the same guide notes that since January 1, 2025, a reconvened meeting for director elections can proceed with 20 percent in specified cases.
The California State Bar's Business Law Section has also observed that nonprofits often want certain directors to be required for quorum, and that the Corporations Code does not clearly say this is allowed. If you are considering a clause like that, get legal advice first.
Close corporations and special provisions
A statutory close corporation can operate under a shareholders' agreement, and the statute defines that agreement as a written agreement among all the shareholders. That is the setting where a quorum above a majority may be possible. It is also a setting where you need an attorney, since the close corporation election has formal requirements in the articles.
If you also plan an S corporation election, remember that it runs on a separate clock from your governance paperwork. The Form 2553 deadline checklist lays out the filing window so your tax election and your corporate records line up.
How to write the quorum clause in your bylaws
Keep it short and tied to the statute. A workable structure:
- State the authorized number of directors (or a range) in the bylaws.
- Set the board quorum as a majority of the authorized number, or a lower fixed fraction if you need it, never below the § 307 floor.
- State the vote needed to act: the act of a majority of directors present at a meeting with quorum, unless the law requires more.
- Allow adjournment by a majority of those present when quorum is lacking.
- Set the shareholder quorum as a majority of shares entitled to vote, or a lower fraction that is not below one-third, and mirror any lower number in the articles.
- Address remote attendance so that participation by phone or video counts as presence if your bylaws and the statute allow it.

Our perspective: quorum is a records problem
We see quorum problems less as a legal puzzle and more as a records problem. The statutes are not hard to read. What goes wrong is that a founder copies a template with a quorum number that does not match the board size, or the board shrinks after a co-founder leaves and nobody amends anything, or the minutes say "the board approved" without saying who was there.
Three habits fix most of it. First, check the quorum clause against your actual authorized number of directors every time you hold the annual meeting. Second, put an attendance line at the top of every set of minutes, and record any departures. Third, keep the bylaws and articles consistent, because a conflict between them is where disputes start.
The annual meeting is also the natural moment to confirm all of this. Our notes on the annual meeting requirement and on drafting annual minutes show how to fit it in without much effort. We are not a law firm, and this article is general information. For contested votes, investor deals or a close corporation election, talk to a California business attorney.

Getting bylaws and minutes done
If you want the paperwork handled, we prepare annual minutes, bylaws and changes throughout the year for California corporations at 147 USD one-off, along with a registered agent service at 99 USD one-off. You can see both on our compliance page. If you would rather form and document the corporation yourself, our Incorporation Course is 37 USD one-off and walks through the steps.
Mistakes that make votes challengeable
- Counting filled seats instead of authorized seats. A board with vacancies still needs a quorum based on the full authorized number.
- Quorum number below the statutory floor. A clause setting quorum at one director on a five-seat board conflicts with § 307 and may not be enforceable.
- No attendance record. Without it, you cannot show a quorum existed.
- Acting by an unqualified group after others leave. Check that each vote still has a majority of the required quorum.
- Using a nonprofit or HOA rule for a for-profit company. The numbers differ by corporation type.
- Skipping adjournment. When quorum fails, adjourn and document it rather than informally "checking in" with absent directors.
FAQ
What is the default quorum for a California corporation board?
A majority of the authorized number of directors, under Corporations Code § 307, unless the articles or bylaws say otherwise. The bylaws can lower it, but not below the larger of one-third of the authorized directors or two.
Can bylaws set quorum at one director?
Only if the corporation is authorized to have a single director. For a larger board, the statutory floor of at least two directors, and at least one-third of the authorized number, applies.
What is the shareholder quorum in California?
A majority of the shares entitled to vote, present in person or by proxy, under § 602. The articles can provide a lesser quorum, but not below one-third of the shares entitled to vote.
What happens if there is no quorum?
No business can be validly transacted, but a majority of the directors present can adjourn the meeting to another time and place. Record the attendance and the adjournment in the minutes, then reconvene.
Do nonprofits use the same quorum rules?
No. A public benefit corporation follows § 7211, where bylaws cannot go below the larger of one-fifth of authorized directors or two. Membership associations and HOAs have their own member quorum rules.
