California Corporation Bylaws Requirements: Provisions, Records, and Amendments

California corporation bylaws requirements are set almost entirely by the corporation itself. The California Corporations Code mandates only that the bylaws fix the number of directors unless the articles do (Section 212(a)), and that a current copy of the bylaws sit at the corporation’s principal California office, open to shareholder inspection (Section 213). Everything else, from shareholder meeting notice and quorum to officer removal, indemnification and the amendment threshold, is a drafting choice that either overrides a statutory default or inherits it. Bylaws are never filed with the California Secretary of State. Close corporations and professional corporations carry extra statutory constraints, and once shares are issued a bylaw changing a fixed board size needs shareholder approval rather than a board vote.

Corporate lawyers at law firms handling California formations spend their drafting time on the discretionary provisions rather than the two mandates, because the Corporations Code default that applies when the bylaws are silent is often the wrong answer for a closely held company. The analysis changes for close corporations and professional corporations, and a corporation that never adopts bylaws inherits every Code default by operation of law.

Key takeaways

1. California corporation bylaws requirements under the Corporations Code are narrow: Section 212(a) requires the bylaws to fix the number of directors unless the articles do, and Section 213 requires a current copy at the principal California office, open to shareholder inspection.
2. Bylaws are never filed with the California Secretary of State.
3. After shares are issued, a bylaw changing a fixed board size needs approval of the outstanding shares, not a board vote alone (Section 212(a)).
4. Close corporations (Section 158) and professional corporations (Moscone-Knox) add statutory constraints that ordinary bylaws do not carry.

Are bylaws required to form a corporation in California?

Bylaws are not required to form a corporation in California. The articles of incorporation filed with the California Secretary of State create the entity, and the bylaws govern it afterward, adopted internally by the incorporators or the initial board rather than filed with the state. Section 212(a) of the Corporations Code nonetheless makes a bylaw necessary in most formations: it requires the number of directors to appear in either the articles or the bylaws, so a California corporation whose articles are silent on board size has no lawful way to fix that number except by adopting a bylaw.

Who adopts the first bylaws

1. The incorporators, before the initial board is seated.
2. The initial board, at the organizational meeting, shortly after the articles are filed.
3. The corporation’s secretary, who records the adoption in the minutes rather than filing it anywhere.

That minute entry is the document diligence counsel and a lender’s counsel ask to see when they want proof that a board actually exists.

What California law requires corporate bylaws to contain

The California Corporations Code imposes only two hard bylaw requirements on a California corporation. Section 212(a) requires the bylaws to set the number of directors, or a stated minimum and maximum, unless the articles state it instead. Section 213 requires the corporation to keep the original or a current copy of its bylaws at its principal California office and to open them to shareholder inspection at all reasonable times during office hours. Every other provision is discretionary in a specific sense: the Code supplies a governing default whenever the bylaws are silent, so the drafting question is which defaults to keep and which to displace.

Section 212(a) also sets the mechanics of the director-number provision. A corporation may fix a single number, or it may set a variable board with a stated minimum and maximum, where the maximum cannot exceed two times the minimum minus one, and the exact number within those limits is then fixed by the board or the shareholders as the bylaws provide. The number or minimum cannot be fewer than three directors except in a short list of cases.

Exceptions to the three-director minimum

1. One or two directors before shares are issued.
2. One or two directors so long as the corporation has only one shareholder.
3. Two directors so long as the corporation has only two shareholders.

A supermajority voting requirement, by contrast, has to live in the articles rather than the bylaws (Section 204(a)(5)).

Not every state starts from this rule. The Delaware rules on bylaws carry no comparable director-number mandate inside the bylaws themselves, which matters to counsel moving a formation between states and assuming the California default travels with it.

California nonprofit corporations incorporate under the Nonprofit Corporation Law rather than the General Corporation Law. The bylaw requirements for a 501(c)(3) add provisions on purpose and the dedication of assets that a California for-profit corporation never carries.

What provisions California corporate bylaws should include

Provisions with no statutory default

Two rows in the table above have no Corporations Code default at all, and a third is left almost entirely to the bylaws:

1. The conflict of interest policy.
2. The fiscal year.
3. The specific mechanics of asset distribution on dissolution, beyond the statutory scheme.

Director number and board size: the one mandated provision

A variable-board bylaw might read: “The authorized number of directors of the corporation shall be not less than three nor more than five until changed by an amendment of this bylaw duly adopted by the board or the shareholders.” A bylaw that instead fixes a single number, rather than stating a variable range, cannot be changed by the board alone once shares are issued:

1. Resizing the board takes shareholder approval rather than a board vote (Section 212(a)).
2. The corporation cannot add a seat in a financing round without going back to the shareholders.

A firm that expects frequent board changes early in a corporation’s life typically drafts the variable-board formula from the outset rather than a fixed number.

Indemnification

California’s indemnification scheme supplies the floor; the bylaws set how far past that floor the corporation goes. A bylaw naming the elective scope of indemnification provisions typically covers:

1. Advancement of defense costs before a final adjudication.
2. The standard of conduct a director or officer must meet.
3. Whether the corporation carries director and officer liability insurance.

Counsel drafting this provision for a close or professional corporation should check it against the share-transfer and licensing constraints that apply to those entities.

Shareholder and board meeting provisions in California bylaws

Shareholder meeting notice, quorum and board meeting mechanics are the provisions California bylaws most often decide, because the Corporations Code defaults apply only where the bylaws say nothing. Section 600(b) requires an annual shareholder meeting for the election of directors, on a date and at a time stated in or fixed in accordance with the bylaws. Section 600(a) lets shareholders who are not physically present participate by electronic transmission, video screen, conference telephone or other remote communication, but only if the board authorizes it and subject to any limitation the articles or bylaws impose. Section 307(a) supplies the board defaults: regular meetings may be held without notice when the bylaws or the board fix the time and place, and special meetings take four days notice by mail or 48 hours notice delivered personally, by telephone or by electronic transmission. One limit cannot be drafted around: neither the articles nor the bylaws may dispense with notice of a special board meeting.

Remote participation is a board authorization, not a shareholder right

Section 600(a) makes remote attendance a board authorization rather than an automatic shareholder right. Bylaws that are silent on the point, or that are drafted to forbid or condition remote attendance, still control until the board affirmatively opens the meeting to remote participation.

1. The board decides whether to allow remote participation, not the shareholders.
2. The articles or bylaws can narrow or condition that authorization further.
3. The authorization has to come from the board before the meeting, not announced at it.

What happens if the annual meeting is missed

A missed annual meeting does not dissolve the corporation or void its actions. Section 600(c) gives a shareholder the right to petition the superior court for an order calling the meeting once the corporation has gone more than 60 days past the date set for it, or, where the bylaws designate no date, more than 15 months since its organization or last annual meeting. A board that lets the date slip is exposed to that petition rather than to a statutory fine.

Where California corporate bylaws must be kept and who can inspect them

California corporate bylaws must be kept at the corporation’s principal office in California, or at its principal California business office if the overall principal office sits outside the state, and Section 213 keeps them open to shareholder inspection at all reasonable times during office hours. A corporation whose principal office is outside California and that has no principal office in this state at all has to furnish a copy of the bylaws as amended to date on the written request of any shareholder. Section 1500 sets the surrounding record obligation: adequate and correct books and records of account, minutes of shareholder, board and committee proceedings, and a shareholder record showing names, addresses and shareholdings.

Where the bylaws must be kept

1. A corporation headquartered in California keeps its bylaws at its principal office.
2. A corporation headquartered elsewhere but with a principal California business office keeps them there.
3. A corporation with no principal office in this state must furnish a copy on written shareholder request.

Who can inspect the bylaws and the corporation’s other records

Bylaws are not public, but shareholders have statutory access to them and to the corporation’s other records. Section 1601 opens the accounting books, records, and board and shareholder minutes to inspection on written demand by any shareholder, at the corporation’s principal office in California or, if there is none, at the physical location of its registered agent for service of process in this state, for a purpose reasonably related to that holder’s interest as a shareholder. Section 1601(a)(2) gives an alternative: the shareholder may request the documents by mail or electronically and pay the reasonable copying or conversion cost instead of inspecting in person. Section 1600 goes further for a defined group: a shareholder or shareholders holding at least 5 percent of the outstanding voting shares, or at least 1 percent if they have filed a Schedule 14A with the Securities and Exchange Commission, have an absolute right to the shareholder list on five business days written demand. Section 213 and Section 1500 were both amended in 2022 (Stats. 2022, Ch. 617, SB 1202), effective January 1, 2023.

How to amend California corporate bylaws

California corporate bylaws are amended or repealed either by approval of the outstanding shares or by approval of the board under Section 211, unless the articles or bylaws restrict or eliminate the board’s power to do it. Section 212(a) then carves out the amendment that most often goes wrong.

Board-size amendments that need shareholder approval

Once shares have been issued, a bylaw adopted by the board alone cannot do any of the following. Each one needs approval of the outstanding shares instead:

1. Specify or change a fixed number of directors.
2. Change the stated maximum or minimum of a variable board.
3. Switch the board between a fixed and a variable structure.

A minute recording a board-only vote on any of these is a defect diligence counsel looks for.

The 16 2/3 percent limit on reducing board size

Section 212(a) layers on a further limit. A bylaw or articles amendment reducing the fixed or minimum number of directors below five cannot be adopted if either of the following exceeds 16 2/3 percent of the outstanding shares entitled to vote:

1. The votes cast against its adoption at a meeting.
2. The shares not consenting to it, in the case of a written consent.

Reviewing bylaws on a cycle

Counsel typically revisit a corporation’s bylaws:

1. On an annual cycle.
2. Whenever the board resizes.
3. When the corporation closes a financing round or adds a share class.
4. When an officer or committee structure changes.
5. When the Corporations Code itself is amended, as it was for Sections 213 and 1500 in 2022.

Bylaw requirements for a California close corporation

California close corporation bylaws look like ordinary bylaws, because the two features that create close corporation status sit in the articles rather than in the bylaws. Section 158 defines a close corporation as one whose articles cap the holders of record of all classes at a specified number not exceeding 35 and state, in those words, that the corporation is a close corporation. Section 202(a) adds that the corporate name must contain corporation, incorporated or limited, or an abbreviation of one of them. What changes for the drafter is the relationship between the close corporation bylaws and a shareholders agreement: Section 186 defines that agreement as a written agreement among all of the shareholders, and Section 300(b) protects it from attack on the ground that it interferes with the discretion of the board or treats the corporation as a partnership.

What makes a corporation a close corporation

1. The articles cap all classes of record holders at a stated number, not exceeding 35.
2. The articles state, in those words, that the corporation is a close corporation.
3. The corporate name contains “corporation,” “incorporated” or “limited,” or an abbreviation of one.
4. Spouses and a personal representative of either count as a single holder; a trust or a decedent’s personal representative also counts as one.

Amending close corporation status after shares are issued

Adding the close-corporation provisions by amendment after shares are issued takes the affirmative vote of all issued and outstanding shares of all classes. Deleting them, or changing the specified shareholder number, takes at least two thirds of each class of outstanding shares, unless the articles set a lower threshold not below a majority or deny the vote to a class. Status changes almost never happen by board vote alone: a close corporation planning a round that would exceed the 35-holder cap has to amend the articles before the round closes, not after.

Bylaw requirements for a California professional corporation

A California professional corporation drafts bylaws under the General Corporation Law plus the Moscone-Knox Professional Corporation Act, which controls wherever the two conflict (Section 13403). Three Moscone-Knox constraints have to be reflected in the governance documents. Shares may be issued only to licensed persons, and shares issued in violation of that restriction are void (Section 13406(a)). A shareholder may not vest voting power in anyone other than a shareholder of the same corporation, so a voting trust or proxy running to any other person, licensed or not, is void (Section 13406(a)). And on death or disqualification from practice, the shares may be transferred only to the corporation, to another shareholder of the corporation, to a person licensed in the practice jurisdiction, or to a professional corporation; if neither the corporation acquires the shares nor the disqualified shareholder or the deceased shareholder’s representative transfers them within 90 days of disqualification or six months of death, the governmental agency regulating the profession may suspend or revoke the corporation’s certificate of registration (Section 13407).

Share ownership, voting and transfer restrictions

1. Shares issued to a non-licensee are void from the start (Section 13406(a)).
2. Voting power cannot be vested in anyone outside the corporation’s own shareholder group (Section 13406(a)).
3. Shares of a disqualified or deceased shareholder have 90 days, or six months on death, to transfer before registration risk attaches (Section 13407).

Single-shareholder and two-shareholder professional corporations

Moscone-Knox scales the board and officer requirements down for the smallest professional corporations (Section 13403):

1. A one-shareholder professional corporation needs only one director, who must be that shareholder and must also serve as president and treasurer; the other officers need not be licensed.
2. A two-shareholder professional corporation needs only two directors, who must be the two shareholders and who fill president, vice president, secretary and treasurer between them.

Professional services may be rendered only through licensed employees, though the corporation may employ unlicensed staff for everything else (Section 13405). The licensing board regulating the profession adds its own registration requirement on top of these governance rules (Section 13401).

Do S corporations and C corporations need different bylaws?

S corp bylaws and C corp bylaws are the same document, because S corporation and C corporation are federal tax elections rather than California entity types. A corporation formed under the California General Corporation Law carries identical bylaw requirements whether it files Internal Revenue Service Form 2553 to elect S corporation treatment or remains taxed as a C corporation. The election does constrain what the bylaws and the articles may do with shares, because Subchapter S permits one class of stock and caps shareholders at 100.

What the S election constrains in the bylaws and articles

1. Authorizing a second, preferred class of stock can terminate the election.
2. A transfer provision that lets shares reach an ineligible holder, such as a nonresident alien or another corporation, can terminate the election.
3. Exceeding 100 shareholders can terminate the election.

What happens if a California corporation operates without bylaws

A California corporation operating without bylaws falls back on the Corporations Code defaults, and the Code sets no fine or administrative penalty for the omission itself.

Internal deadlock

A corporation whose articles are silent on board size and that never adopted a Section 212(a) bylaw has no fixed number of directors and therefore no reliable quorum for a board action or a director election.

Transaction risk

Buyer and lender counsel routinely request the bylaws alongside the board’s adopting minutes, and an absent set can stall the closing checklist.

Veil piercing exposure

California’s alter ego doctrine disregards the corporate form only where a plaintiff shows both elements below:

1. A unity of interest and ownership between the corporation and its shareholder, such that the two no longer have separate identities.
2. An inequitable result if the corporation’s acts are treated as its alone.

Disregard of formalities, including never adopting bylaws, is one fact courts weigh inside the first element, not an independent basis for piercing.

How Spellbook supports California bylaw drafting

Lawyers use AI software for drafting corporate bylaws to cut the first pass, and Spellbook does that inside Microsoft Word as an AI suite for transactional legal work, with the attorney reviewing and approving each provision before the board adopts it. The Draft feature proposes provision language from a prompt and the firm’s own precedent, grounded in the firm’s playbooks and in 20M+ real contracts rather than produced by a general model alone. The Review feature reads a bylaw set a client arrives with and surfaces risky or missing provisions against the firm’s own playbook, as native Word tracked changes the lawyer accepts, edits or rejects.

Spellbook is a commercial contract specialist, not a corporate records or entity management platform. It does not replace the minute book, the stock ledger or the filings a corporation makes with the Secretary of State; the lawyer still owns those records and decides what the bylaws finally say.

Frequently asked questions

Do California corporate bylaws need to be signed?

The Corporations Code does not require signatures on corporate bylaws, and Section 213 speaks only to keeping the original or a copy available for shareholder inspection. In practice the secretary certifies the bylaws and the board’s adopting resolution is recorded in the minutes, which is what diligence counsel asks for.

Are corporate bylaws filed with the California Secretary of State?

No. The articles of incorporation are filed and public. The bylaws are not filed. Section 213 requires the corporation to keep a current copy at its principal California office and open it to shareholder inspection instead.

Are corporate bylaws publicly available?

No. Bylaws are not filed with the Secretary of State and are not public. Shareholders may inspect them under Section 213, and may inspect the corporation’s broader books, records and minutes under Sections 1600 and 1601.

What is the difference between bylaws and the articles of incorporation?

The articles of incorporation create the corporation, are filed with the California Secretary of State and are public. The bylaws govern the corporation afterward, are adopted internally and are not filed. Where the two conflict, the articles control, and anything the Code requires to appear in the articles, such as a supermajority voting requirement under Section 204(a)(5) or close corporation status under Section 158, cannot be accomplished by bylaw alone.

Are corporate bylaws legally binding?

Yes. Bylaws bind the corporation, its directors, officers and shareholders as the entity’s internal governing document. They are enforceable between those parties rather than as a contract with an outside counterparty.

Do bylaws override a shareholders agreement?

It depends on whether the corporation is a close corporation. In a close corporation, Section 300(b) protects a written agreement among all the shareholders from attack on the ground that it interferes with the board’s discretion or treats the corporation as a partnership, so that agreement can and does displace what the bylaws would otherwise govern. Outside a close corporation, a shareholders agreement binds the parties to it but does not amend the bylaws.

How often should corporate bylaws be reviewed?

On a fixed annual cycle, and outside that cycle whenever the board resizes, the corporation closes a financing round or adds a share class, an officer or committee structure changes, the Corporations Code is amended, as Sections 213 and 1500 were in 2022, or the corporation’s principal office moves, since that changes where Section 213 requires the bylaws to be kept.
