Corporate Board Meeting and Written-Consent Requirements in Arizona

At a glance

Requirements one by one

The board ordinarily directs the corporation

A.R.S. § 10-801 requires a board and places corporate powers and management under its authority and direction. Articles of incorporation or a qualifying shareholder agreement under § 10-732 may limit that arrangement. A board packet therefore cannot establish authority without the current governing documents and any such agreement.

A.R.S. § 10-803 requires one or more individual directors. Articles or bylaws may set a fixed number or a minimum-maximum range, with shareholders or the board fixing the actual number within that range. This page addresses an ordinary domestic private business corporation, not a nonprofit, professional, public, foreign, or specially regulated entity.

Ordinary caller and adjournment mechanics come from governing documents

A.R.S. § 10-820 permits regular and special meetings inside or outside Arizona. The reviewed ordinary meeting, notice, and waiver provisions do not name a default individual caller or prescribe a general adjournment procedure. The articles, bylaws, and valid prior board action need to supply those mechanics, including whether a changed time or place after adjournment requires new notice.

Arizona has a separate emergency route. A.R.S. § 10-207 permits emergency bylaws to set call procedures, quorum, and additional or substitute directors when a quorum cannot readily be assembled because of a local emergency, state of emergency, or state of war emergency as defined in § 26-301. If those bylaws do not say otherwise, A.R.S. § 10-303 allows notice only to directors practicable to reach by any practicable method and allows officers to be deemed directors in rank and seniority order as needed for quorum. This is not a general route for an inconvenient ordinary meeting.

Special meetings default to two days' notice

A.R.S. § 10-822 allows regular meetings without notice unless the articles or bylaws provide otherwise. A special meeting ordinarily needs at least two days' notice of its date, time, and place; the purpose is unnecessary unless the articles or bylaws require it.

A.R.S. § 10-141 generally permits notice in person, by telephone, fax, electronic transmission, wire or wireless communication, mail, or private carrier. Notice is written unless oral notice is reasonable, and oral notice is barred where the Act specifically requires writing. Written notice to a director is effective when received, five days after properly addressed prepaid mailing, or on a signed return-receipt date, whichever applicable event occurs first; oral notice is effective when comprehensibly communicated.

Under A.R.S. § 10-823, a director may sign a written waiver before or after the stated date and time and file it with minutes or corporate records. Attendance or participation also waives notice unless the director objects at the beginning or promptly on arrival and then does not vote for or assent to action taken.

Remote meetings require simultaneous hearing

A.R.S. § 10-820 allows the board to permit any or all directors to participate through any communication method by which every participating director may simultaneously hear the others, unless articles or bylaws provide otherwise. A director using that route is deemed present in person. The section does not add a visual, identity-verification, or meeting-recording condition, but an asynchronous message exchange is not this kind of meeting.

Fixed and variable boards use different quorum denominators

A.R.S. § 10-824 uses a majority of the fixed number for a fixed-size board. For a variable-range board, it uses a majority of the prescribed number or, if no number has been prescribed, the number of directors in office immediately before the meeting begins. That last denominator is meeting-specific and should not be replaced with a generic authorized-seat or directors-present count.

Articles or bylaws may authorize a quorum of at least one-third of the fixed or prescribed number. Quorum must be present when the vote occurs, so a departure that drops attendance below the applicable quorum prevents later ordinary action even if the meeting began with quorum.

Majority of those present ordinarily acts, and presence can become assent

With quorum, A.R.S. § 10-824 makes a majority of directors present the ordinary board act unless articles or bylaws require a greater number. An abstention does not count as an affirmative vote.

A present director is nevertheless deemed to assent unless the director preserves a call objection at the beginning or promptly on arrival, has dissent or abstention entered in the minutes, or delivers written dissent or abstention to the presiding officer before adjournment or to the corporation before 5 p.m. on the next business day. A director who voted in favor cannot use those routes.

Consent defaults to unanimity and can be revoked before the last signature

A.R.S. § 10-821 permits action without a meeting unless articles or bylaws say otherwise, but all directors must act. One or more consents must describe the action and, in the aggregate, bear every director's signature. Consents and signatures may be written or electronic and must be included in minutes or corporate records in paper format when the minutes are paper and electronic format when the minutes are electronic.

The action is effective when the last director signs unless the consent states a different effective date. Before that last signature date, any director may revoke by delivering a signed revocation to the president or secretary. The consent then has the effect of a meeting vote. Because the default requires every director, the section has no later notice rule for nonconsenting directors.

Committees inherit board procedure but not every board power

A.R.S. § 10-825 permits the board to create one or more committees and appoint one or more directors to serve at the board's pleasure. Creation and appointments require the greater of a majority of all directors in office or the governing- document number required for board action. The board may designate alternate directors to replace absent committee members.

The meeting, consent, notice, waiver, quorum, voting, dissent, and revocation rules in §§ 10-820 through 10-824 apply to committees. A committee still cannot authorize distributions; approve or submit shareholder-required action; fill board or committee vacancies; amend articles under § 10-1002; adopt, amend, or repeal bylaws; approve a merger not requiring shareholder approval; approve share reacquisition outside a board formula; exercise share-issuance powers outside specifically prescribed limits; or set director compensation.

Minutes, records, and cure questions remain separate

A.R.S. § 10-1601 requires permanent board minutes, board-action-without-meeting records, and delegated committee-action records. They may be written or kept in another form capable of conversion into writing within a reasonable time.

The current official Title 10 index contains separate director-conduct and conflicting-interest provisions but no standalone defective-corporate-action ratification or validation chapter. Ordinary minutes or a later resolution should not be treated as automatically curing an earlier authorization defect. Fiduciary, conflict, public-company, securities, lender, tax, regulatory, and contested-authority outcomes are outside this procedure survey.

What trips people up

Variable-range boards do not always use the number currently serving. If the corporation has prescribed an actual number within the range, that prescribed number controls; directors in office immediately before the meeting becomes the denominator only when no number is prescribed.

Arizona's consent record must match the format of the minutes. Paper minutes require paper filing; electronic minutes require electronic filing. A signed consent can also be revoked by delivery to the president or secretary until the last director signs.

Meeting-notice waiver and presumed assent are separate. A timely objection can preserve both issues, but a director who later votes for or assents to the action cannot rely on the attendance-waiver exception, and an affirmative voter cannot later claim statutory dissent or abstention.

Common questions

Can any Arizona director call a special board meeting?

The ordinary Act provisions reviewed here do not grant that power to every director. Check the articles, bylaws, and valid board resolutions for the authorized caller and call procedure.

Does a special-meeting notice need an agenda?

Not by default. It must give the date, time, and place at least two days ahead, but articles or bylaws may require a purpose statement or a different rule.

Can a director join by video or telephone?

Yes, if the board permits the method and the articles or bylaws do not provide otherwise. Every participating director must be able to hear every other participant simultaneously.

Can a committee act by unanimous electronic consent?

Yes, if the committee was validly created and delegated the matter. The board consent statute applies to committees, including unanimity, signature, revocation, effective-time, and matching-format record rules, but the matter cannot be one of § 10-825's barred or limited powers.
