New York: Corporate Bylaws Adoption and Amendment Requirements

Requirements one by one

Initial adoption is an incorporator task

Business Corporation Law §§ 404 and 601 say the initial bylaws “shall be
adopted” by the incorporators at the organization meeting after corporate
existence begins. Any incorporator may call the meeting. When there are two or
more incorporators, the caller mails at least five days' notice stating the time
and place; attendance or a signed waiver excuses notice.

The same organization action may occur without a meeting only when each
incorporator or attorney-in-fact signs an instrument setting out the action.
That specific unanimous route is different from the later shareholder-consent
rules in § 615.

Later shareholder power is automatic; board power is not

Under § 601, shareholders may adopt, amend, or repeal bylaws by a majority of
the votes cast by shares then entitled to vote for directors. They may also act
by written consent under § 615: unanimity is the baseline, while the certificate
may permit the minimum vote that would authorize the action at a meeting and
nonconsenting shareholders must receive prompt notice.

The board receives no automatic bylaw power from § 601. The certificate or a
shareholder-adopted bylaw must authorize it and may specify a vote greater than
the chapter's ordinary board rule. Even then, shareholders entitled to vote may
amend or repeal a board-adopted bylaw.

Special thresholds and board-size provisions use separate rules

BCL § 616 places greater shareholder quorum or vote requirements in the
certificate of incorporation; § 709 does the same for greater director
thresholds. A bylaw is therefore not the general New York vehicle for raising
those statutory thresholds.

Director-number rules are more specific. BCL § 702 supplies a one-director
default when the number is not otherwise fixed and permits a shareholder-
adopted bylaw to authorize board changes, but the board then must act by a
majority of the entire board and cannot shorten an incumbent's term through a
decrease.

The statutory inspection list does not promise a bylaw copy

The ordinary adoption provisions do not prescribe a signature, certification,
acknowledgment, notarization, or Department of State filing for the bylaws.
BCL § 624 requires books, minutes, and a shareholder record and gives a
qualifying shareholder a statutory route to inspect shareholder minutes and the
shareholder record after written demand. Unlike California and Florida, that
enumerated list does not itself require the corporation to keep or furnish a
current copy of its bylaws under this statutory route.

What trips people up

A board committee cannot perform bylaw work. BCL § 712 expressly withholds
adoption, amendment, and repeal of bylaws from a committee even if its delegated
authority is otherwise broad.

Special corporations can add obligations that do not belong in the ordinary
private-company rule. Under § 708(e)-(f), a residential cooperative corporation
must provide a board-adopted bylaw change in writing within ten days and must
post a change that directly affects occupancy or building rules. BCL § 620's
certificate-based shareholder-control provision separately ceases to be valid
when shares become exchange-listed or regularly quoted over the counter.

Common questions

Can the board adopt the first New York bylaws?

Not under the ordinary initial-adoption rule. Sections 404 and 601 assign the
initial bylaws to the incorporator or incorporators at the organization stage.

Is a majority of all shares required for a shareholder amendment?

Section 601 uses a majority of the votes cast by shares entitled to vote in a
director election, subject to the certificate and other applicable voting
limits. It does not state a blanket majority-of-all-entitled-shares rule.

Must New York bylaws be filed with the Department of State?

Sections 404 and 601 do not make filing a validity step for ordinary bylaws.
They are adopted internally through the organization and later-approval rules.
