LLC Amendment and Legal-Name-Change Filing Requirements in Colorado

At a glance

Requirements one by one

Colorado makes two amendments mandatory

C.R.S. § 7-80-204 sets the original articles fields. C.R.S. § 7-80-209 permits an amendment at any time for any purpose, but it says the articles "shall be amended" when the LLC changes its domestic entity name or the articles contain a false or erroneous statement. The amendment filing itself is spare: the current LLC name and the amendment text. The Secretary's online workflow implements that by requiring a name change, an attachment containing other amended text, or both.

Restatement is a different route. It files the complete current articles text, may incorporate amendments approved under the ordinary rule, and supersedes the original articles plus every prior amendment.

The default approval is every member

Colorado does not infer approval from the person who submits the online form. C.R.S. §§ 7-80-108 and 7-80-401, together with § 7-80-209, require all members to approve an articles amendment unless the operating agreement provides another manner. The operating agreement otherwise controls internal affairs over contrary statutory defaults, subject to the Act's nonwaivable limits.

The filing screen asks for an individual causing delivery, not an authorized signer's signature. That individual affirms the filing, its facts, and legal compliance under penalty of perjury. Current § 7-90-314 also requires written consent or authority to use another person's name or address or deliver the document for the LLC.

Online filing replaces a signed paper form

The Secretary's forms list sends Articles of Amendment and Amended and Restated Articles of Organization through the entity-record search and marks paper forms unavailable. Section 7-90-301 expressly says signature or execution is not a condition of filing. At least one causing individual's true name and mailing address is required.

The current fee is $25 for either amendment or amended-and-restated articles. Payment must be electronic. Under §§ 7-90-303 and 7-90-305 to 7-90-305.5, a reversed or otherwise failed payment means the document was not successfully filed despite any initial timestamp; correction and later change remain distinct.

A delayed date has an automatic statutory cap

Under §§ 7-90-304 and 7-90-304.5, a document without a delay takes effect when filed, and restated articles supersede the earlier articles and amendments. A later filing-day time works only if it is after actual filing. A delayed date/time is capped at the 90th day after filing; entering only a date means 11:59 p.m. on that date. A later date written into the document is automatically pulled back to 11:59 p.m. on day 90.

What trips people up

Correction and change are divided by time. Section 7-90-305 corrects information that was already wrong when delivered, or revokes a filing delivered in error. A later development uses a statement of change. The Secretary's checklist sends principal-office and registered-agent updates to a Statement of Change or the periodic report rather than an articles amendment.

A trade name is another filing entirely. Under §§ 7-90-501 and 7-71-101, the periodic report keeps agent and principal-office information current, while an effective trade-name statement is required before doing Colorado business under a name other than the person's true name. The current trade-name fee is $20. A trade name does not replace the mandatory articles amendment when the LLC changes its legal entity name. Under § 7-90-601, that legal name also must be distinguishable and carry an approved LLC designator.

Common questions

Can a manager alone approve the name change?

Only if the operating agreement validly supplies that approval method. The statutory default is consent of every member, even when managers otherwise make ordinary company decisions.

Do I sign the online Articles of Amendment?

No signature is required as a filing condition. The named individual causing delivery instead makes the statutory affirmation under penalty of perjury and must have the written consent or authority required by § 7-90-314.

What should the company retain?

Keep the accepted amendment or restatement with the articles, operating agreement, approval resolution or consent, and current member-manager records. Members have a statutory inspection right for those categories on reasonable demand related to their membership. Tax, license, bank, contract, property, trademark, trade-name, and other-state registration updates are separate work.
