Corporate Board Meeting and Written-Consent Requirements in South Dakota

At a glance

Requirements one by one

South Dakota Codified Laws § 47-1A-101 names the governing act. South Dakota Codified Laws § 47-1A-801 ordinarily requires a board and puts corporate powers and management under it, while § 47-1A-803 requires one or more directors. The statute, the articles, and the authorized shareholder-agreement exception can alter that baseline.

Meetings, notice, waiver, and emergencies

South Dakota Codified Laws § 47-1A-206 permits bylaws consistent with law and the articles. Section 47-1A-820 permits regular and special board meetings inside or outside South Dakota. Under § 47-1A-822, regular meetings default to no notice, while special meetings default to at least two days' notice stating the date, time, and place. Purpose is unnecessary unless the articles or bylaws require it.

Under § 47-1A-823, a director may sign a written waiver before or after the stated meeting time and file it with the minutes or records. Attendance also waives notice unless the director timely objects and does not then vote for or assent to the action. South Dakota Codified Laws § 47-1A-207 separately permits emergency bylaws to address calls, quorum, and additional or substitute directors when a catastrophe means a quorum cannot readily assemble.

Real-time remote participation counts as presence

Unless the articles or bylaws provide otherwise, § 47-1A-820 permits any or all directors to join through a communications method by which all participants can hear one another simultaneously. Qualifying participation counts as presence in person. That real-time route is distinct from signed consent.

The variable-board denominator matters

South Dakota Codified Laws § 47-1A-824 measures default quorum by a majority of the fixed board. For a variable-range board, it uses the prescribed number or, if none is prescribed, the directors in office immediately before the meeting. The articles or bylaws may authorize a smaller quorum, but not below one-third of the fixed or prescribed number. Quorum must exist when the vote is taken, and a majority of directors present ordinarily acts.

Under § 47-1A-824.1, presence implies assent unless the director timely objects to the meeting, puts dissent or abstention in the minutes, or delivers written dissent or abstention to the presiding officer before adjournment or to the corporation immediately afterward. A director who votes in favor cannot use that dissent route.

Unanimous consent requires delivery

South Dakota Codified Laws § 47-1A-821 permits no-meeting action unless the articles or bylaws require a meeting. Every director must sign a consent describing the action and deliver it to the corporation. The action becomes the board's act when all unrevoked signed consents are delivered. A consent may set the effective time, and a director may withdraw by signed revocation delivered before all unrevoked consents arrive.

A committee may have one member

South Dakota Codified Laws § 47-1A-825 permits one-or-more-director committees. Creation and appointments need the greater of a majority of all directors then in office or the governing-document number required for board action. The meeting, consent, notice, waiver, quorum, vote, and dissent provisions apply to the committee too.

Section 47-1A-825.1 bars committees from exceeding board-set distribution limits, approving or proposing shareholder-required action, filling listed vacancies, or adopting, amending, or repealing bylaws. South Dakota Codified Laws § 47-1A-825.3 permits board-appointed alternates and supplies a unanimous substitute-member route unless the governing documents or committee resolution provide otherwise.

Board and committee actions remain corporate records

South Dakota Codified Laws § 47-1A-1601 requires permanent board-meeting minutes, records of all board action without a meeting, and records of committee action taken in place of the board. The records may be written or kept in another form capable of conversion into writing within a reasonable time.

What trips people up

A consent is not complete merely when everyone signs

Section 47-1A-821 makes delivery to the corporation part of the statutory architecture. The act occurs when all unrevoked signed consents have been delivered, and revocation remains possible before that point.

Common questions

May one director serve alone on a South Dakota board committee?

Yes, if the committee was validly created and the governing rules do not say otherwise. Section 47-1A-825 permits one or more board members, but delegation remains subject to the limits in § 47-1A-825.1.

Does valid board procedure approve every underlying transaction?

No. A merger, charter amendment, distribution, share issuance, conflict transaction, financing, asset sale, or dissolution may carry separate statutory, contractual, shareholder, filing, or fiduciary requirements.
