A Delaware LLC operating agreement is the private contract that controls ownership, capital contributions, voting rights, and profit distribution for your company. Without one, Title 6, Chapter 18 of the Delaware Code fills every gap with default rules that won't fit most businesses.

When I review a Delaware LLC document, one of the first things I check is the title. Delaware does not technically call it an “operating agreement.” Under the statute, the correct term is “limited liability company agreement.”
That wording matters more in Delaware than in most states. The Court of Chancery interprets the document under that label, so I always tell clients to match the document title to the statutory language Delaware law actually uses.
If the agreement is meant for a Delaware LLC, I want the title and wording to reflect Delaware terminology from the start, not generic language borrowed from a 50-state template.
What Is a Delaware LLC Operating Agreement?
Under Delaware Code § 18-101(9), a limited liability company agreement is any agreement, written, oral, or implied, that governs the affairs of the LLC. The definition covers the conduct of the company's business broadly. Even a handshake between two members counts. Oral agreements are nearly impossible to enforce in the Court of Chancery, though, and implied agreements leave members guessing about who owns what.
Unlike a Certificate of Formation (the only document filed with the Division of Corporations when you form a Delaware LLC in five steps), the operating agreement isn't submitted to any state agency. The State of Delaware doesn't require member names on the Certificate of Formation. That makes the operating agreement the primary record of who the LLC's members are and how profits get divided.
One detail worth flagging: § 18-101(9) explicitly states that a single-member LLC agreement “shall not be unenforceable by reason of there being only 1 person who is a party” to it. Delaware treats single-member agreements as fully valid contracts.
Does Delaware Require a Written Operating Agreement?
Short answer: no. Section 18-101(9) says a Delaware LLC “is not required to execute its limited liability company agreement.” The agreement can exist in writing, orally, or by implication.
Here's the thing, though. Every Delaware LLC has an agreement whether the members wrote it down or not. If nothing is on paper, the Delaware Limited Liability Company Act (Title 6, Chapter 18) supplies the default terms for every internal rule. Those terms won't match most businesses.
Those defaults aren't always favorable. The In re Carlisle Etcetera LLC case illustrates the risk. The Court of Chancery had to determine who was even a member of the LLC, and ultimately ordered dissolution on equitable grounds. A written agreement costing less than $200 would have prevented years of litigation.
For single-member LLCs, the veil-piercing risk is real. Without a signed operating agreement documenting the member's capital contribution, courts can hold the owner personally liable. Banks and financial institutions routinely request this document before opening an account.

Delaware Default Rules the Operating Agreement Should Override
Skip the operating agreement and you're stuck with whatever Title 6, Chapter 18 prescribes. These defaults apply automatically when the LLC operating agreement is silent, and they don't always match how members run the business.
Management and Voting Defaults Under § 18-402
Without an operating agreement designating a manager, management is vested in members in proportion to each member's interest in profits. Decisions are controlled by members owning more than 50% of the profit interest.
One thing to watch: § 18-402 also gives every member and manager the authority to bind the LLC to third-party contracts. One member can sign a lease or commit the company to a vendor agreement without consulting anyone. The only way to restrict that authority is through the operating agreement.
Profit and Loss Allocation Under § 18-504
Delaware allocates distributions based on each member's interest in profits. Unlike some states that default to equal splits regardless of capital contributions, Delaware ties distributions to profit percentage. That sounds fair until two members disagree about what their percentages actually are. Defining the amount and class of each member's interest in writing eliminates that argument.
Transfer of Membership Interests Under § 18-702
By default, a member can assign their economic rights (profit distributions) to a third party without other members' consent. The assignee doesn't become a full member; full admission requires consent from all existing members unless the agreement says otherwise.
The catch: without transfer restrictions, a member could assign their economic interest to a competitor, an ex-spouse, or a creditor. Most LLC members don't realize that risk until it's too late.
| Provision | Default Rule (No OA) | With Operating Agreement |
|---|---|---|
| Management | Members, by profit interest (§ 18-402) | Member-managed or manager-managed; custom thresholds |
| Binding authority | Every member and manager can bind the LLC | Designated signatories only, with dollar limits |
| Distributions | Per profit interest (§ 18-504) | Custom allocation classes; preferred returns |
| Transfer of interest | Economic rights assignable; full admission needs all-member consent | Right of first refusal; drag-along/tag-along; board approval |
| Amendment | All members must approve (§ 18-302(f), post-2012 LLCs) | Supermajority or specified approval process |
| Dissolution | Per § 18-801 triggers | Custom triggers; buy-sell upon death or disability |
I’ve watched multi-member Delaware LLCs run into serious trouble because nobody clearly limited who could sign for the company. Under § 18-402, every member can sign contracts on behalf of the LLC unless the operating agreement says otherwise.
In one matter I saw, a co-member signed a five-year office lease without telling the rest of the ownership group. By the time everyone found out, the company was stuck dealing with a $180,000 problem.
I look for a clause that says who may sign, what kinds of contracts they can approve, and when majority member approval is required first. That is the practical safeguard.
A single paragraph restricting signature authority to members approved by majority vote would have prevented that lease issue. I never treat this clause as optional in a multi-member Delaware LLC.
What to Include in Your Delaware LLC Operating Agreement
A Delaware operating agreement should cover every gap the LLC Act would otherwise fill with a default rule. Below are the provisions that matter most.
Capital Contributions and Membership Interest
Document each member's initial capital contribution, whether cash, property, or services. Section 18-101 defines a member's limited liability company interest as their share of profits, losses, and distributions.
Delaware permits multiple classes of membership interests with different voting rights, economic rights, or both. A common structure: Class A units carry full voting and economic rights; Class B units carry economic rights only. This flexibility is one of the core benefits of forming a Delaware LLC, and the operating agreement is where those classes get defined.
Management Structure: Member-Managed vs. Manager-Managed
Delaware's statute doesn't use the terms “member-managed” or “manager-managed” the way other states do. Section 18-402 simply defaults to member management unless the agreement designates one or more managers.
The agreement can set up a board-of-managers structure that functions like a corporate board of directors. Managers don't need to be members. Delaware also allows delegation of management rights under § 18-407, unless the agreement restricts it.
Dissolution and Winding Up Under § 18-801
The default dissolution triggers under § 18-801 apply unless the operating agreement overrides them. The In re Carlisle Etcetera LLC decision (Court of Chancery, 2015) shows the risk: the court ordered equitable dissolution after finding that members couldn't agree on basic governance. A well-drafted dissolution clause with specific voting thresholds and buyout procedures prevents Chancery from making that decision for you.
Freedom of Contract: What Makes Delaware Different
Delaware's LLC Act isn't just another state statute. It's built on a fundamentally different philosophy.
Section 18-1101(b) states the policy plainly: “to give the maximum effect to the principle of freedom of contract and to the enforceability of limited liability company agreements.” Members can structure their company however they want, as long as the agreement doesn't violate the handful of non-waivable provisions in the statute.
Under § 18-1101(c), members can modify or even eliminate fiduciary duties in the operating agreement. They can't eliminate the implied covenant of good faith and fair dealing, but everything else is on the table. Private equity firms, venture-backed startups, and real estate holding companies overwhelmingly choose Delaware for exactly this reason.
The Court of Chancery (§ 18-111) has exclusive jurisdiction over disputes involving LLC operating agreements. Chancery judges specialize in business entity law and don't sit with juries. Unlike a Delaware corporation, where bylaws and the certificate of incorporation set the governance framework, a Delaware LLC's operating agreement is the single controlling document. Boost Suite's full breakdown of Delaware LLC costs explains the financial tradeoffs of choosing Delaware over a home state.
One genuine limitation: freedom of contract cuts both ways. If the agreement contains a bad provision, a court will still enforce it. The agreement is only as good as its drafting.
Series LLCs and the Operating Agreement
Delaware invented the Series LLC in 1996, and the operating agreement is the engine that makes it work. A Series LLC allows a single limited liability company to create multiple “series,” each with its own members, assets, interests, and liabilities. Debts of one series can't reach the assets of another, provided each series maintains separate records.
Since 2019, Delaware recognizes two types. Protected series (§ 18-215) are created entirely through the operating agreement with no state filing. Registered series (§ 18-218) require filing a certificate of registered series ($75 annual tax per series). They appear in the state's public records and receive their own certificate of good standing.
The 2024 amendments (HB 336, effective August 1, 2024) clarified merger, consolidation, and dissolution rules for both types. For LLC owners considering a Series structure, the operating agreement must define how each series is established, who the members are, and how assets stay segregated. Without that precision, a court won't hesitate to disregard the series structure entirely.
Series LLCs are popular with real estate investors holding multiple properties under a single entity. Banks and financial institutions increasingly accept registered series for lending because of that separate good-standing certificate.

How to Draft and Sign a Delaware LLC Operating Agreement
Drafting a Delaware operating agreement doesn't require an attorney, but it does require attention to Delaware-specific rules. LLC owners who draft an operating agreement without understanding these defaults risk locking in provisions that conflict with the statute.
Use the exact LLC name from the Certificate of Formation, including the “LLC” or “L.L.C.” designation. A mismatch between the two documents can delay bank account openings. Before drafting, verify the name through the Delaware business entity search tool to confirm the formation filing went through.
Identify all members and document their capital contributions with exact dollar amounts. Specify each member's percentage interest in profits and losses, and define any separate classes of interests with different voting or economic rights.
Set the management structure. If the LLC will be manager-managed, name the initial managers and define their authority, including any actions that require member approval. Include transfer restrictions with at least a right of first refusal. Define dissolution triggers and the voting threshold required to dissolve voluntarily.
Get all members to sign. Delaware law doesn't require execution or notarization, and the agreement isn't subject to the statute of frauds (§ 18-101(9)). A signed, written agreement is still far stronger in court than a verbal understanding. After signing, apply for an EIN through IRS Form SS-4. Most registered agent services in Delaware can coordinate the formation filing, EIN application, and initial compliance steps.
Choose the version that fits your LLC structure.
Delaware LLC Formation Costs and Ongoing Compliance
As a private document, the operating agreement carries no filing fee. Forming the LLC itself requires a Certificate of Formation filed with the Division of Corporations for $90. Delaware LLC processing times vary depending on whether you file online or by mail.
Every Delaware LLC owes a $300 annual franchise tax, due June 1 each year. No annual report is required; the only obligation is the $300 payment. Miss the deadline and the state adds a $200 penalty plus 1.5% monthly interest. That adds up fast: after 12 months, the total owed reaches $554.
No reminder notices arrive from the state. Boost Suite's guide to the Delaware annual report and franchise tax covers the payment process in detail. For Series LLCs, each registered series owes an additional $75 annual tax. Protected series don't owe a separate tax. Choosing the right Delaware LLC formation service can simplify ongoing compliance for multi-entity structures.
This is the Delaware deadline I tell LLC owners to calendar themselves, because confusion usually starts when they assume the corporate timeline applies to them too.
The June 1 franchise tax deadline trips up more Delaware LLC owners than almost any other compliance item I deal with. After years of working with filing clerks across 25+ states, I have seen the same mistake over and over: owners mix up the Delaware LLC deadline with the separate March 1 corporate deadline, then get hit with a penalty they could have avoided.
This is the date many owners remember, but it applies to Delaware corporations, not LLCs.
This is the one that matters for LLCs: $300 due online, with no annual report attached to it.
Once June 1 passes, the state adds a $200 penalty. That usually happens not because the tax is complicated, but because the owner was following the wrong Delaware deadline.
I tell clients to set a personal calendar alert for May 15, so they have a built-in buffer and do not depend on anyone else to surface the deadline for them.
Pay the $300 Delaware LLC tax online before June 1. It usually takes only a few minutes, but missing it creates an avoidable compliance problem.
Common Questions About Delaware LLC Operating Agreements
Delaware's LLC Act gives members more flexibility than any other state. That freedom also creates more questions. Below are the ones Boost Suite's editorial team encounters most often.
Is an operating agreement legally required for a Delaware LLC?
No. Delaware Code § 18-101(9) states that a limited liability company is “not required to execute its limited liability company agreement.” Every LLC has one by default, though. Without a written document, the LLC Act's default provisions govern internal operations.
Can a single-member LLC have an operating agreement in Delaware?
Yes. The statute specifically provides that a single member agreement isn't unenforceable because only one person is a party to it. Single-member LLC owners should execute a written agreement documenting their initial capital contribution and the company's separate legal identity.
Do you file the operating agreement with the State of Delaware?
No. The operating agreement is a private contract between the LLC's members. It isn't filed with the Division of Corporations or any other state agency. The only formation document filed with the state is the Certificate of Formation.
Can a Delaware LLC operating agreement eliminate fiduciary duties?
Yes, under § 18-1101(c). Members can modify or eliminate fiduciary duties in the operating agreement. The one limit: the implied covenant of good faith and fair dealing can't be eliminated. This level of contractual freedom is one of Delaware's strongest draws for sophisticated business owners.
What happens if LLC members disagree and there's no written agreement?
Default rules under Title 6, Chapter 18 apply. Disputes go to the Court of Chancery, where litigation costs tens of thousands of dollars. In Carlisle Etcetera, the absence of a clear agreement led to court-ordered dissolution.
Does a Delaware LLC operating agreement need to be notarized?
No. Delaware law doesn't require notarization, witnessing, or any specific formality. The agreement isn't even subject to the statute of frauds under § 18-101(9). Members should still sign and keep a copy with the company's records.
How do you amend a Delaware LLC operating agreement?
If the agreement includes an amendment procedure, follow it. If silent, § 18-302(f) requires approval of all members for LLCs formed on or after January 1, 2012. The 2024 LLC Act amendments also clarified that an agreement can be amended through a merger under § 18-209(f), even if the agreement's own amendment provisions don't address mergers.
