LLC Amendment and Legal-Name-Change Filing Requirements in Illinois
At a glance
| Governing law and covered public record | Illinois Limited Liability Company Act, 805 ILCS 180; amend or restate the public Articles of Organization through Articles of Amendment filed with the Secretary of State (Art. 5) |
|---|---|
| Mandatory, permitted, and restatement routes | May amend at any time to add, change, or remove a provision permitted in current original articles; Article 5 states no general inaccuracy-amendment deadline. Restated Articles integrate all operative provisions, supersede prior articles/amendments, and cost $150 (§§ 5-10, 5-30, 50-10) |
| Legal name and availability | Legal-name change uses Articles of Amendment. Name must contain limited liability company/L.L.C./LLC, avoid barred entity terms and restricted words, and be distinguishable on SOS records; a court decree can establish prior right (§ 1-10) |
| Internal approval and private consents | Default is consent of all members, subject to a lawful operating-agreement rule. Majority of managers may act without members only to remove a former manager, remove initial agent/office data after a change statement, swap LLC designator/add geography, or make a no-change restatement (§§ 5-15, 15-1(d)(2), 15-5) |
| Filing contents and attachments | Execute and file in duplicate; state the current LLC name, complete text of each amendment, and that approval complied with the operating agreement or Act, plus a delayed-effective date if used. Attach continuation text when the form space is insufficient (§ 5-25; LLC-5.25) |
| Signer, filing channel, and fee | A company-authorized person signs, states name/capacity, and affirms truth and authority under penalty of perjury; a filed signing authorization must be written and sworn, verified, or acknowledged. Eligible domestic good-standing non-series name changes without delay may file online; other amendments use paper LLC-5.25. Base fee $50 (§§ 5-45, 50-10; SOS) |
| Effective time, delay, and rejection | Effective on SOS filing or a stated date no more than 30 days later; the online name-change route does not accept a delayed date. SOS may reject a nonconforming filing, unavailable name, unpaid filing, or an amendment blocked while the LLC is delinquent (§§ 5-25, 5-35, 5-55, 50-15) |
| Correction, change, report, and assumed-name alternatives | Use § 5-47 correction for an original misstatement, transcription/typographical defect, or defective execution; use §§ 1-36/1-37 for agent/office changes, the annual report for current principal-office and manager data, and § 1-20 for a separate assumed name. Current fees are $25 for correction or agent/office change (§§ 50-1, 50-10) |
| Post-filing records, registrations, and status effect | SOS stamps and returns the duplicate; keep the amended/restated articles and any signing power with company records. Filed articles give notice of their stated facts, but the Illinois filing does not itself update tax, license, bank, contract, title, trademark, assumed-name, or foreign-registration records; delinquency blocks amendments (§§ 1-40, 5-55, 5-70, 50-15) |
Requirements one by one
Governing law and covered public record
Article 5 of the Illinois Limited Liability Company Act governs an amendment to the public Articles of Organization. The filing is called Articles of Amendment. An internal operating-agreement change, assumed name, annual report, or registered-agent statement is a different record.
Amendment and restatement routes
Under 805 ILCS 180/5-10, an LLC may amend at any time, but the amended articles may contain only provisions permitted in current original articles. Article 5 does not impose a general deadline to amend every later inaccuracy.
Section 5-30 supplies a no-change consolidation route: Restated Articles collect all currently operative provisions, identify the present and original names and original filing date, and supersede the earlier articles and amendments. The current statutory fee is $150 under § 50-10(b)(1), versus $50 for Articles of Amendment.
Legal name and availability
Section 1-10 requires “limited liability company,” “L.L.C.,” or “LLC,” bars corporate and limited-partnership designators, and requires the proposed name to be distinguishable on the Secretary of State's records. Restricted words remain subject to the other statute creating the restriction. A name database result does not decide trademark or unfair-competition rights.
Internal approval and private consents
The default under § 15-1(d)(2) is consent of all members for an Article 5 amendment, whether the LLC is member-managed or manager-managed. Section 15-5(a) allows a lawful operating agreement to modify Act rules governing relations among members, managers, and the company, so read the current agreement before using the default. The required filing then certifies that approval complied with the agreement or Act (§ 5-25).
Section 5-15 is the narrow exception. A majority of managers may act without member approval only to remove a former manager, remove initial agent or office data after a change statement is on file, swap the full LLC designator for its abbreviation or add a geographical attribution, or restate the articles without changing their operative provisions. A broader legal-name change is not on that list.
Filing contents, signer, channel, and fee
Section 5-25 requires duplicate Articles of Amendment stating the LLC's current name, the complete amendment text, the approval statement, and any delayed date. The February 2026 LLC-5.25 form provides continuation space and gives the Springfield filing address.
Under § 5-45, a person authorized by the LLC signs, states the signer's name and capacity, and affirms truth and authority under penalty of perjury. A filed power or other signing authorization must be written and sworn, verified, or acknowledged.
The base amendment fee is $50 under § 50-10(b)(2). The Secretary's online route is limited to eligible Illinois domestic LLCs making only a name change: the LLC must be in good standing, cannot be authorized to establish series, and cannot request a delayed date. Other amendments use paper LLC-5.25.
Effective time and rejection
Sections 5-25 and 5-35 make the amendment effective on filing or on a stated date no more than 30 days after filing. Section 5-55 permits rejection when the filing does not conform to law or the fee is not paid. The online instructions also say an unavailable proposed name or other issue produces an email notice and charge reversal. A delinquent LLC must first cure the delinquency because § 50-15 blocks additional amendments and other filings.
Correction, agent, report, and assumed-name alternatives
A § 5-47 Statement of Correction is for a filed record that originally contained a factual misstatement, transcription or typographical error, other defect, or defective execution. It relates back to the original filing date, but cannot replace another filing the Act requires.
An agent or registered-office change has its own duplicate statement under §§ 1-36 and 1-37 and becomes effective when filed. The annual report states current principal-office, manager, and manager-authority-member information under § 50-1. A business name other than the true LLC name uses the separate assumed-name application under § 1-20 rather than changing the legal name.
Accepted filing and company records
Section 5-55 requires the Secretary to stamp the filing date, retain the original, and return the duplicate. Section 1-40(a)(2) requires the LLC to keep its amended or restated articles and executed signing powers. Under § 5-70, the filed articles give notice of the facts they state.
Those effects stop at the Illinois public record. Update tax accounts, licenses, permits, banks, contracts, property titles, trademarks, assumed-name records, and foreign registrations through their own processes.
What trips people up
- Manager management does not ordinarily eliminate the member vote. The default for an Article 5 amendment is all-member consent. Section 5-15's manager-only route is limited to four listed housekeeping changes.
- A true legal-name change and a DBA are different. Articles of Amendment change the LLC's true name; § 1-20 registers an additional assumed name.
- Online filing is narrower than the paper form. The online route is for an eligible name-only amendment with no delayed date. Other changes use paper LLC-5.25.
- Correction is not a retroactive amendment shortcut. Section 5-47 fixes a defect in the filed instrument as of the original action; it cannot stand in for a filing otherwise required by the Act.
Common questions
Can managers alone approve a complete new legal name?
Not under the § 5-15 housekeeping exception. It covers swapping the LLC designator or adding geography, not an unrestricted new name. Apply the operating agreement and the § 15-1 all-member default.
Can the amendment take effect next quarter?
No. Illinois caps the delayed date at 30 days after filing, and the online name-change route does not accept a delayed date.
Does a name change update registrations in other states?
No. The Illinois filing changes the Illinois articles. Each foreign-registration, tax, licensing, contract, bank, title, and trademark record has its own update process.
