Corporation Charter Amendment and Legal-Name-Change Requirements in Colorado

At a glance

Requirements one by one

Colorado files articles of amendment online

Under § 7-110-101, a Colorado corporation may add or change a provision that is currently required or permitted in its articles, or delete one that is not required. Section 7-110-106 calls the filing articles of amendment and sends it through the general Secretary of State filing system in article 90.

The current forms page lists online filing for profit-corporation Articles of Amendment and says a paper form is unavailable. The filing is found by searching for the corporation's existing public record.

A general legal-name change is not board-only

Under § 7-90-601, the new name ordinarily must be distinguishable in the Secretary of State's records and contain corporation, incorporated, company, limited, or a listed abbreviation.

Under § 7-110-102, the board may, without shareholders, swap one permitted corporate designator for another or add, delete, or change a geographical attribution. It also allows a reinstatement-related name fix. A change to the distinctive part of the legal name ordinarily follows the proposal and shareholder-approval process in § 7-110-103.

Before shares issue, directors or incorporators act

Section 7-110-105 supplies a short pre-share route. The board may adopt the amendment. If no directors have been elected, the incorporators may do so. The statute does not import the post-share shareholder vote into this route.

Directors or 10% holders may propose the amendment

Under § 7-110-103, the board or holders representing at least 10% of all votes entitled to be cast on the amendment may propose it. The proposing board or shareholders may condition effectiveness on any basis.

The board must recommend the amendment unless shareholders proposed it or the board decides that a conflict of interest or other special circumstance supports no recommendation. In that no-recommendation route, the board communicates its basis to shareholders with the amendment. The amendment statutes state no general post-approval abandonment power.

Notice is usually 10 to 60 days, but share increases get 30 days

The corporation gives every shareholder entitled to vote meeting notice that states amendment consideration as a purpose and contains the amendment or a summary. Section 7-107-105 normally requires notice 10 to 60 days before the meeting. If the amendment increases authorized shares, at least 30 days' notice is required.

Under § 7-107-104, unanimous written consent is available unless the articles require a meeting. Less-than-unanimous consent requires express authorization in the articles and the minimum votes that would carry the action with every entitled share present and voting. The necessary consents must arrive within 60 days after the first consent, and nonconsenting entitled holders receive notice with the material that would have accompanied meeting notice.

Ordinary approval uses votes cast

Sections 7-107-206 and 7-107-207 provide the default. A majority of the votes entitled to be cast by a voting group is a quorum, subject to the one-third statutory floor. With a quorum, the votes favoring the amendment must exceed the votes opposing it. The articles, or shareholder bylaws authorized by the articles, may require a greater quorum or vote.

Under § 7-110-104, listed changes to class or series rights trigger separate voting-group approval. The statutory vote applies even if the articles otherwise make the affected shares nonvoting.

Amendment appraisal is limited

Under § 7-113-102, appraisal automatically applies when an amendment reduces a holder's class or series shares to a fraction that the corporation may or must repurchase. Other amendments create appraisal only to the extent the articles, bylaws, or a board resolution provides. Publicly traded and specified investment-company shares are generally excluded, subject to statutory exceptions.

The online filing states the name and amendment text

Section 7-110-106 requires the current domestic entity name and the text of each amendment. An exchange, reclassification, or cancellation of issued shares also needs implementation provisions if the amendment itself does not contain them.

The current online instructions use the corporation's prefilled ID, name, and jurisdiction. A new name is entered directly; other amendments and share-change implementation provisions are attachments.

Colorado uses a filer affirmation, not a signature block

Under § 7-90-301, no signature or execution is required as a filing condition. The document identifies at least one individual causing delivery and gives that person's mailing address. Under § 7-90-301.5, causing delivery is a perjury affirmation that the filing is authorized, believed true, and compliant. The current instructions therefore ask for a filing individual's name and mailing address rather than a notarized officer signature.

The online fee is $25 and payment completion matters

The current Secretary of State fee schedule lists a $25 online fee and no paper option for both amendment and amended-restatement filings. The instructions say the document is not filed until payment.

Chapter 226, effective August 12, 2026, makes that point consequential: if payment is not successfully processed or is reversed, the document was not successfully filed despite an initial timestamp. The Secretary of State may mark it void and adjust status or remove it from the online filing system.

Under § 7-90-304, an accepted document is effective at filing unless it states a later effective time or date. A date beyond 90 days is pulled back to 11:59 p.m. on the 90th day. A delayed filing may be revoked before effect by the statement-of-correction route described in subsection (3).

Restatement consolidates the operative articles

Under § 7-110-107 and § 7-90-304.5, the board may restate the articles with or without shareholder action; before shares and directors, incorporators may do so. Any included amendment still needs the approval required by the corporate act. Once effective, the restatement supersedes the original articles and prior amendments. The current forms and fee pages list online amended-and-restated articles for $25 with no paper form.

No ordinary statewide publication or proof-of-publication step appears in the current amendment provisions or online instructions. Section 7-110-109 keeps former-name proceedings alive. Tax, license, contract, title, trademark, banking, and foreign-registration updates remain outside the Colorado filing itself.

Agent, correction, and bylaw changes are separate

Under § 7-90-702, registered-agent changes use a statement of change, periodic report, or prescribed form or cover sheet. They are not a reason to rewrite the substantive articles.

Section 7-90-305 permits correction of information that was incorrect when the record was delivered, and permits revocation of a delayed filing or a record delivered in error. Correction generally relates back, except for a person who relied on the prior record and is adversely affected. It does not replace approval for a newly chosen substantive amendment.

Under § 7-110-201, directors and shareholders have separate bylaw powers, subject to statutory, charter, and shareholder-adopted restrictions. A bylaw edit does not change the public articles.

This survey excludes public-benefit elections, nonprofit and professional corporations, cooperatives, regulated and public companies, securities and tax consequences, foreign qualifications, investor and lender consents, and disputed board, shareholder, fiduciary, fraud, or control issues.
