Corporate Bylaws Adoption and Amendment Requirements in Colorado
At a glance
| Governing law and covered corporation | Colorado Business Corporation Act, Title 7, articles 101-117; ordinary domestic lawful-business corporation, subject to separate special-class statutes (§ 7-103-101) |
|---|---|
| Initial-bylaw duty and no-bylaws defaults | Permissive: organization provisions say bylaws may be adopted 'if desired'; no ordinary no-bylaws substitute stated (§§ 7-102-105 to -106) |
| Adoption authority | Board first; incorporators if no directors are elected; shareholders only if neither incorporators nor board adopted initial bylaws (§ 7-102-106) |
| Organizational action and timing | Majority-called incorporator or initial-director organization meeting; incorporators may use unanimous written consent; no adoption deadline stated (§§ 7-102-105, 7-108-202) |
| Permitted contents and limits | May manage the business and regulate corporate affairs if consistent with law and the articles; internal-claim forum bylaws cannot exclude Colorado courts or compel arbitration (§§ 7-102-106, -108) |
| Amendment, repeal, and reserved power | Concurrent power; board power yields to statutory/articles reservation or a particular bylaw's express board prohibition (§ 7-110-201) |
| Higher-vote and special-bylaw rules | Articles-authorized greater shareholder thresholds use the greater current-or-proposed test and are board-proof; board-threshold and meeting-place bylaws follow actor-of-origin rules (§§ 7-110-202 to -203) |
| Signature, filing, records, and inspection | No general execution or public-filing step stated; keep bylaws at principal office and allow direct inspection after 5-business-day written demand (§§ 7-116-101 to -102) |
| Shareholder-agreement and entity boundaries | Special-class statutes may displace or supplement the Act; emergency bylaws are separately board-adopted and shareholder-amendable (§§ 7-103-101, 7-102-107) |
Requirements one by one
Colo. Rev. Stat. § 7-103-101 places ordinary corporations formed under articles 101 through 117 in the lawful-business framework used here. It also preserves separate statutes for special corporate classes and excludes nonprofit corporations formed or governed under articles 121 through 137 from this ordinary-business-corporation analysis.
Initial adoption is optional but follows a sequence
Colorado's organization section says incorporators or initial directors may adopt bylaws “if desired.” Section 7-102-106 supplies the actor sequence. The board may adopt the initial bylaws; incorporators may do so if no directors have been elected; and shareholders may step in if neither the incorporators nor the board has adopted them.
If the articles do not elect initial directors, a majority of the incorporators may call an organization meeting to adopt bylaws and elect a board. A majority of the initial directors may call their organization meeting to adopt bylaws, appoint officers, and conduct other business. Incorporators may act without a meeting through the unanimous written-consent method in § 7-108-202. The surveyed organization sections state no deadline for adopting bylaws.
Any adopted provision must concern management of the business or regulation of corporate affairs and remain consistent with Colorado law and the articles.
Board and shareholders ordinarily share later power
Colo. Rev. Stat. § 7-110-201 allows the board to add, change, or delete bylaw provisions at any time, while shareholders retain amendment authority even when the board also has it. Board power yields when the Act or articles reserve power wholly or partly to shareholders or when a particular bylaw expressly bars board amendment.
A board committee cannot exercise this authority. Section 7-108-206 expressly withholds adoption, amendment, and repeal of bylaws from committees.
Higher-vote bylaws carry stronger protection
An articles authorization is required before shareholders may amend the bylaws to impose a greater shareholder quorum or voting requirement. Adding, changing, or deleting that rule must satisfy whichever threshold is greater: the one currently in effect or the one proposed. The board cannot amend such a bylaw.
Board quorum or voting bylaws and bylaws requiring a shareholder meeting to be held at a place use an actor-of-origin rule. A shareholder-adopted version is shareholder-controlled unless the bylaws provide otherwise; a board-adopted version may be changed by either actor. Shareholders may also specify the vote needed for later amendment of a board quorum or voting rule. Board action must meet the greater current-or-proposed threshold.
Under §§ 7-102-107 and 7-102-108, Colorado separately permits board-adopted emergency bylaws unless the articles provide otherwise, but shareholders may amend or repeal them. A forum bylaw may select Colorado courts and additional courts with a reasonable relationship, but it cannot bar an internal corporate claim from Colorado courts or compel arbitration of that claim.
Current bylaws stay at the principal office
Section 7-116-101 requires the corporation to keep its bylaws at its principal office. Under § 7-116-102, a shareholder may inspect and copy them during regular business hours after giving written demand at least five business days before the requested date. The articles or bylaws cannot abolish or limit that inspection right.
The additional three-month-or-5% ownership, good-faith, proper-purpose, and particularity conditions in § 7-116-102 apply to the separate additional-records tier, not to the direct principal-office records tier containing the bylaws. The surveyed provisions state no general signature, acknowledgment, notarization, certification, or Secretary of State filing step for ordinary bylaws.
What trips people up
Optional adoption does not mean every actor has equal priority. Shareholders reach the initial bylaws only after neither the incorporators nor the board has adopted them.
General concurrent amendment power does not override an articles reservation, a particular bylaw's express board prohibition, or the special greater-vote rules. A board committee also cannot use delegated board authority to amend the bylaws.
The direct inspection tier matters. A shareholder must give five business days' written demand, but the ownership-duration and proper-purpose conditions for additional records do not attach to the current bylaws kept at the principal office.
Common questions
Must a Colorado business corporation adopt bylaws?
No general duty appears in the surveyed provisions. Section 7-102-105 describes organization-meeting adoption as action taken “if desired,” and § 7-102-106 uses permissive “may” language.
Who may adopt the initial bylaws?
The board may adopt them. If no directors have been elected, the incorporators may act. Shareholders may act only if neither the incorporators nor the board has adopted initial bylaws.
Can shareholders protect a bylaw from board amendment?
Yes. A particular bylaw may expressly prohibit board amendment. The Act also makes an articles-authorized greater-shareholder-quorum or voting bylaw board-proof.
Does a shareholder need a proper purpose to inspect current bylaws?
No proper-purpose condition appears in the direct § 7-116-102(1) tier. The shareholder gives written demand at least five business days before inspecting and copying the bylaws at the principal office.
