How to Amend an LLC Operating Agreement (and When You Need Unanimous Consent)

How do you amend an LLC operating agreement, step by step?

Most amendments follow the same sequence. Skipping a step is the most common reason an amendment is later challenged.

• Read the amendment clause and any clause that gives particular members consent or veto rights over specific changes.
• Draft the amendment in writing, quoting the exact sections being changed and the new wording.
• Give notice to members as the agreement requires, or circulate a written consent if the agreement allows action without a meeting.
• Obtain the required vote or signatures, including any separate consent from members who are disproportionately affected.
• Date and sign the amendment, attach it to the original agreement and keep it with the company records.
• File an amendment to the articles with the state if information in the articles has changed.
• Update anything that depends on the change: the ownership schedule, bank signature cards, tax filings and contracts.

What does the amendment clause say, and who must approve?

The amendment clause is the rule that governs every other rule. Delaware makes this explicit: if an LLC agreement provides for the manner in which it may be amended, it may be amended only in that manner or as otherwise permitted by law (6 Del. C. §18-302(e)). Common approaches include unanimous consent, a supermajority such as two-thirds or 75 percent of units, a simple majority of units, or approval by the manager alone for limited technical changes.

Read the clause together with the rest of the agreement. Many agreements say a general amendment needs a majority but list specific changes, such as increasing capital obligations or changing distribution rights, that need the consent of each affected member. Some give an investor or a class of units a separate veto. A vote that meets the general threshold but ignores one of these carve-outs may not be valid.

Does amending an operating agreement require unanimous consent?

Only if the agreement says so or the agreement is silent and your state's default requires it. In Delaware, if the LLC agreement does not say how it may be amended, it may be amended with the approval of all of the members (6 Del. C. §18-302(f), which applies to LLCs whose original certificate of formation was filed on or after January 1, 2012). Florida's default, which applies unless the operating agreement says otherwise, requires the affirmative vote or consent of all members to amend the operating agreement in both member-managed and manager-managed companies (Fla. Stat. §605.04073(1)(d) and (2)(e)).

Many other states that follow the Revised Uniform LLC Act have a similar unanimous default. If your agreement has no amendment clause, plan on getting every member to sign, and consider adding a clear amendment clause in the same document so the next change is simpler.

Which changes need which approval?

These are common patterns, not legal requirements. Your agreement's own clause controls, and your state's default applies only where the agreement is silent.

What should a written amendment include?

A good amendment is short, precise and impossible to misread. It should stand on its own so that someone picking it up years later can see exactly what changed and why it was valid.

• The company's exact legal name, state of formation and the date of the original agreement being amended.
• A recital of the approval obtained, such as "approved by members holding at least 75 percent of the units, as required by Section 12.1."
• The exact text being deleted or replaced, by section number, and the new wording in full.
• An effective date, and a statement that all other terms of the agreement remain in force.
• An updated ownership schedule if units or percentages change.
• Signature lines for every member whose vote or consent was required, including any separate consent from an affected member.

Should you sign an amendment or an amended and restated agreement?

A short amendment works well for one or two targeted changes: it lists the sections being replaced and says everything else stays in force. The downside is that after several amendments, nobody can read the agreement as a whole without piecing together four documents.

An amended and restated operating agreement replaces the old agreement entirely with a clean, complete version. It is the better choice when you admit a new member, change the economics or make several changes at once. It needs the same approval as any other amendment. Make sure the restated version expressly supersedes the prior agreement and all earlier amendments, and that any rights you meant to keep, such as an earlier member's buyout note, are carried across.

Can the majority amend the operating agreement against a minority member?

Sometimes, and this is the risk to check before you ever sign the original agreement. If a simple majority can amend, the majority can usually rewrite capital calls, distribution order or buyout pricing without you. Courts generally enforce amendment clauses as written, because you agreed to them.

Protection comes from the drafting. Fair agreements require a supermajority for ordinary amendments and the consent of any member whose economic rights or obligations would be changed disproportionately. Delaware also says that, unless the agreement provides otherwise, a clause requiring an amendment to pass by the same vote needed to act under the provision being amended protects only the provisions that expressly include it (§18-302(e)), so a supermajority vote for an action does not automatically stop a lower vote from amending that provision. Read it carefully. Beyond the clause, managers and controlling members may owe duties, and Delaware keeps the implied covenant of good faith and fair dealing even when duties are limited, but those claims are hard and expensive to bring. A clear consent right is far better protection than a lawsuit.

Do you need to file an operating agreement amendment with the state?

Usually not. The operating agreement is a private document, so changes to it are not filed. What does need a filing is any change to information that appears in the articles of organization or certificate of formation, such as the company name, registered agent, or managers or members if your articles list them. Delaware uses a certificate of amendment for this; most states call it articles of amendment.

Some changes trigger other paperwork. Admitting or removing a member of an LLC taxed as a partnership changes the tax reporting for the year, a change in ownership can affect licenses and lender consents, and a single-member LLC that adds a second member normally changes its default tax classification under Treas. Reg. §301.7701-3. Talk to your accountant before the amendment takes effect, not after.

When should you amend your operating agreement?

Owners tend to amend only when forced to, but the agreement is cheapest to change when everyone still gets along. These events are the usual signals that the document no longer matches the business.

• A member joins, leaves, dies, divorces or sells part of their interest.
• The company raises money from an investor or takes on a significant loan.
• One owner starts doing most of the work, or stops working in the business.
• The company changes its tax classification, such as electing S corporation status.
• You move from member-managed to manager-managed, or replace the manager.
• The business buys real estate or other assets that change the stakes of a buyout.

Can an amendment change what happened in the past?

Owners sometimes want an amendment to "fix" something that already happened, such as recording that a member's percentage was always lower, or approving a transaction after the fact. Members can often ratify past actions, and an amendment can state an earlier effective date for internal purposes. But an amendment generally cannot rewrite rights that third parties already relied on, and backdating a document to make it look as if it was signed earlier is a different matter that can create serious problems.

If you need to correct the record, say so plainly: sign the amendment with today's date, describe the earlier action being ratified, and state the date from which the members agree it applies. Talk to your accountant before changing anything that affects tax allocations for a year already reported.

Common mistakes when amending an operating agreement

Before you circulate an amendment, run the current agreement and the proposed changes through a review so you can see which clauses control the vote and which members must consent.

• Changing the deal by email or handshake without a signed written amendment.
• Getting a majority vote when the agreement required unanimous consent or a separate member consent.
• Forgetting to update the ownership schedule after a new member joins or someone is bought out.
• Leaving the articles out of date, so the public record names a former manager.
• Patching a single-member agreement for a new partner instead of replacing it with a full multi-member agreement.
• Not giving the notice the agreement requires before a meeting or written consent.
