Filing an LLC operating agreement is not something you actually do: no state accepts the document, and no agency keeps a copy. You draft it, every member signs it, and you store it with your company’s internal records. The U.S. Small Business Administration states plainly that operating agreements “are not required to be filed, nor will they be accepted by your state.”1U.S. Small Business Administration. Basic Information About Operating Agreements
The confusion usually comes from mixing the operating agreement up with the articles of organization. Those are two different documents. The articles of organization (sometimes called a certificate of formation) are the public filing you submit to your state to create the LLC in the first place. The operating agreement is a private contract among the members that governs how the company runs. One goes to the Secretary of State. The other stays in your filing cabinet.
Does Any State Require You to Have One
Roughly five states legally require every LLC to adopt an operating agreement. Even in those states, the requirement is only that the document exists and the members have agreed to it. You still don’t send it anywhere. If your state mandates one and you never created it, you could run into trouble if the LLC’s governance is ever challenged in court.
In the states without a mandate, nothing forces you to put the agreement together. But skipping it means your state’s default LLC statute controls every question the agreement would have answered, and those defaults are often not what the owners actually want. More on that below.
Signing the Agreement
Every member should sign the final version. For a single-member LLC, that means you sign it yourself. The signatures are what give the agreement its legal force among the members, so this step is not optional.
Electronic Signatures Are Valid
You don’t need to gather everyone in a room with a pen. Electronic signatures are legally valid for an operating agreement under federal law. The Electronic Signatures in Global and National Commerce Act provides that a contract or signature cannot be denied legal effect solely because it is in electronic form.2Office of the Law Revision Counsel. 15 U.S. Code 7001 – General Rule of Validity Every state has also adopted either the Uniform Electronic Transactions Act or an equivalent statute recognizing electronic signatures.
Notarization Is Usually Not Required
Notarization is not legally required for an operating agreement in most situations. Some banks, however, ask for notarized copies before opening a business account. Having the signatures notarized at the outset is cheap and avoids a second round later. It also adds a layer of identity verification that can matter if anyone later disputes whether a member actually signed.
Where to Store It
Because no agency holds a copy, the only version that exists is yours. Keep the original signed agreement somewhere secure, whether that’s a physical file with your other formation documents or a locked digital repository. Every member should receive a complete copy for their own records. If you store the agreement digitally, keep a backup in a separate location so a lost laptop or a corrupted drive doesn’t take the only copy with it.
You should be able to find the document quickly. It gets requested more often than people expect.
When You’ll Be Asked to Produce It
Even though no regulator will ever review your operating agreement, outside parties ask to see it in several routine situations:
- Banks and lenders frequently require a copy before opening a business account or extending credit, even for single-member LLCs. Without one, you may struggle to prove your authority to act on the company’s behalf.
- Accountants and tax preparers may need it to confirm how the LLC is classified and how income and losses are allocated among members.
- Auditors and the IRS can request it during an audit, particularly to confirm that profit and loss allocations in a multi-member LLC match what the agreement says.
- Opposing parties and courts may demand it during litigation involving the company or its members.
For a single-member LLC, the agreement also plays a defensive role. Courts deciding whether to “pierce the veil” and hold the owner personally liable for business debts look at whether the LLC was treated as a genuinely separate entity. A signed operating agreement is one of the clearest pieces of evidence that it was.
Amending the Agreement Later
The agreement isn’t a document you sign once and forget. Business changes, and the agreement needs to change with it. Common reasons to amend include adding or removing a member, switching from member-managed to manager-managed, adjusting profit-sharing ratios, or updating buy-sell terms after the company’s value shifts.
The amendment process should be written into the original agreement. Most agreements require approval by a specified percentage of members, often a majority or two-thirds, with unanimous consent reserved for fundamental changes like altering ownership percentages. If the agreement is silent on amendments, your state’s default rules apply, and those typically require all members to agree.
Once an amendment is approved, put it in writing, have the required members sign it (electronically is fine), and attach it to the original. Distribute updated copies to every member. Like the original, the amendment stays in your records; it doesn’t go to the state.
What Happens if You Don’t Have One
Skipping the agreement doesn’t leave your LLC without rules. It leaves it governed entirely by your state’s default LLC statutes, which are generic and often don’t match what the owners actually wanted. Some of the more common surprises:
- Many states split profits equally among members regardless of what each person contributed. A member who put in $10,000 gets the same share as one who put in $100,000.
- The default in most states is member-management, so any member can sign contracts, take on debt, or otherwise obligate the entire LLC.
- Adding a new member or letting a member sell their interest to an outsider typically requires unanimous consent of the existing members.
- Some states don’t require the LLC to buy out a departing member. The member who leaves may be left with the limited rights of an assignee, receiving distributions but having no management voice.
- If the sole remaining member dies or withdraws, many default statutes force the LLC to dissolve rather than allowing a successor to step in.
Default rules can also shift when your state updates its LLC statute, which means the terms governing your company can change without you doing anything. A signed operating agreement locks in the rules the members chose and keeps them in place regardless of what the legislature does later.
The Short Version
Draft the agreement. Have every member sign it, electronically or on paper. Keep the signed original in a secure place, give each member a copy, and keep a backup. Amend it in writing when the business changes, following the amendment procedure in the agreement itself. Nothing gets filed with the state, and nothing needs to.
