Why Every LLC Needs an Operating Agreement

A.

Banks Will Refuse Account-Opening Without It

Chase, Bank of America, Wells Fargo, and substantially every commercial bank require an operating agreement before opening a business checking account for an LLC. Without it, your LLC formation documents alone are insufficient: the bank needs to verify signing authority, transactional authority, and the ownership structure. In a 2024 survey by the National Federation of Independent Business, 94% of banks reported requiring an operating agreement for LLC account openings. Online banks (Mercury, Relay, Novo) require one during digital onboarding. Without a business bank account, you cannot maintain the personal-business financial separation that LLC liability protection depends on.
B.

It Is the Single Strongest Evidence of Separate-Entity Status

Courts can “pierce the corporate veil” and hold members personally liable when the LLC fails to operate as a genuine separate entity. An operating agreement is the single strongest piece of evidence that your LLC is a legitimate business structure. In Netjets Aviation Inc. v. LHC Communications LLC (Del. Ch. 2019), the Delaware Chancery Court emphasised that an operating agreement was a key indicator of a properly maintained entity. By contrast, in Shingle Springs Band of Miwok Indians v. Caballero (E.D. Cal. 2019), the court pierced the veil in part because the LLC lacked a formal operating agreement, treating the business as the alter ego of its sole member.
C.

It Displaces Default State Rules That Almost Never Match Intent

Every state has a default LLC statute that operates whenever the operating agreement is silent. These defaults are almost never what members actually want. Under New York's default rules (NY LLC Law § 503), profits and losses split equally regardless of capital contributions: a member who invested $500,000 receives the same share as one who invested $5,000. Under California's default (Cal. Corp. Code § 17704.04), each member has equal voting power regardless of stake. In Texas, default rules permit any member to dissolve the LLC at any time. These outcomes catch LLC owners off guard because they assume the law mirrors their verbal agreements; verbal agreements are notoriously difficult to enforce.
D.

It Defines Death, Incapacity, and Member Exit Before Crisis

Without explicit succession provisions, a member's death can dissolve the LLC by operation of law in many states. Under the Revised Uniform Limited Liability Company Act (RULLCA), adopted by 21 states as of 2026, a deceased member's interest becomes a transferable interest, not a membership interest, meaning the heir receives profit distributions but no voting rights. If your operating agreement specifies that heirs may become full members, or that remaining members must buy out the estate at fair market value, you forestall years of litigation. A 2023 American Bar Association study found that LLC disputes involving estates without clear operating agreements take an average of 2.7 years to resolve, with legal costs averaging $78,000 per party.

Five Threshold Decisions Before You Begin Drafting

  1. Member-Managed or Manager-Managed?

    In a member-managed LLC, every owner participates in daily decisions. This works for two to five active partners running a business together; about 90% of small LLCs choose this structure. In a manager-managed LLC, designated managers handle operations while other members are passive investors. This is suited to LLCs with silent partners, family investment vehicles, or real estate holding companies. State defaults vary: most default to member-managed, but check your statute. See Management Structure.
  2. Distribution Frequency

    Monthly distributions suit service businesses with predictable cash flow. Quarterly is most common, aligning with estimated tax payment deadlines (15 April, 15 June, 15 September, 15 January). Annual distributions suit businesses retaining cash for growth or seasonality. Whatever frequency you select, include a mandatory tax distribution so members can cover their K-1 liability: the IRS taxes LLC members on allocated income whether or not it is distributed.
  3. Decision Thresholds

    Simple majority (over 50%) for routine operations. Supermajority (67% to 75%) for significant matters: debt, leases, large contracts. Unanimous consent for fundamental changes: admitting members, sale of the business, amendment of the operating agreement. For 50/50 LLCs, every decision effectively requires unanimous consent, making tie-breaking provisions essential.
  4. Exit Provisions

    Voluntary withdrawal should require written notice (90 to 180 days) and trigger a buyout at a pre-agreed valuation method. Involuntary removal for cause should require a supermajority vote and a buyout at a discount (10% to 20% below fair market value). Include reasonable non-compete limits and a right of first refusal. See Buyout Provisions.
  5. Death and Incapacity

    The provision most owners skip and most regret. Options: mandatory buyout by remaining members (funded by life insurance), automatic transfer to a named successor, or conversion to an economic interest only. For a two-member LLC where each interest is worth $500,000, a $500,000 term life policy costs roughly $30 to $50 per month for a healthy 35-year-old. The cost of omission, by contrast, is years of probate.

State-Specific Requirements

Five states explicitly require LLC operating agreements by statute. In the remaining 45, agreements are not legally mandated but are practically required for banking, liability protection, and dispute resolution. The following table summarises the strict-requirement jurisdictions; for filing fees, default rules, and recent legislative changes across ten major states, see Requirements by State.

StateStatuteParticular
New YorkNY LLC Law § 417Written agreement required within 90 days of formation. All members must sign.
CaliforniaCal. Corp. Code § 17701.11Written required for multi-member; oral permitted for single-member but inadvisable. $800 annual franchise tax.
DelawareTitle 6, Ch. 18 § 18-101Not strictly required but the Delaware LLC Act gives maximum deference to operating agreement terms.
MissouriMo. Rev. Stat. § 347.081LLCs must adopt an operating agreement. Written form required for enforceability.
MaineMaine LLC Act § 1563Required for foreign LLCs registering in Maine. Strongly encouraged for domestic LLCs.

Even in states without a legal requirement, 94% of banks require an operating agreement for LLC account openings, and courts consistently treat the absence of one as evidence of an improperly maintained entity when evaluating veil-piercing claims.

Frequently Asked Questions

Does a single-member LLC need an operating agreement?+
Yes. Even with a sole owner, an operating agreement is legally required in New York, California, Delaware, Missouri, and Maine. In the other 45 states, banks routinely require one before opening a business account. Without one, courts may disregard your LLC's liability protection (piercing the corporate veil), leaving personal assets exposed. A single-member operating agreement runs 4 to 5 pages and takes under 30 minutes. Read the single-member guide.
Does an operating agreement need to be notarized?+
No state requires notarization of an LLC operating agreement. The document is an internal agreement between members, not a state filing. Witnessed signatures add enforceability. Some banks may request a notarized copy during account opening (bank policy, not legal requirement). For LLCs holding real estate, notarization is recommended because it simplifies title transfers and mortgage applications.
How do I amend an LLC operating agreement?+
Draft a written amendment that identifies the specific sections being changed, states the new language, and is signed by all members (or the threshold specified in your original agreement). Most agreements require unanimous consent for amendments. Reference the original agreement by date and confirm that all other provisions remain unchanged. No state filing is required. See the amendment chapter for scenario-specific templates.
Do I need to file my operating agreement with the state?+
No. Operating agreements are internal documents kept in your company records. You file Articles of Organization (or Certificate of Formation) to create the LLC, but the operating agreement is never submitted to a state agency. You may need to present it to banks, investors, courts, or the IRS, so retain the signed original in a secure location.
What happens if my LLC does not have an operating agreement?+
Your state's default LLC statute fills the gaps. In most states this means equal profit splits regardless of capital contributions, equal voting power per member regardless of ownership percentage, and dissolution requiring unanimous consent. These defaults rarely match members' actual intentions. Courts are also more likely to pierce the corporate veil when there is no operating agreement demonstrating proper entity maintenance.
What is the difference between member-managed and manager-managed LLCs?+
In a member-managed LLC, all members participate in daily operations and can bind the company; about 90% of small LLCs use this structure. In a manager-managed LLC, designated managers (who may or may not be members) handle daily operations while other members are passive investors. Your operating agreement must specify which structure you choose. See Management Structure.
Can I write my own LLC operating agreement without a lawyer?+
Yes. For single-member LLCs with straightforward structures, a template-based agreement is often sufficient. For multi-member LLCs with unequal ownership, complex profit-sharing, or significant assets, attorney review is strongly recommended. Review typically costs $500 to $2,000 depending on complexity and location. The drafting tool above generates a structured outline covering all essential provisions.
What is the difference between an operating agreement and bylaws?+
LLCs use operating agreements; corporations use bylaws. Both serve similar governance functions, but they operate under different legal frameworks. Operating agreements are highly flexible and can be tailored to almost any structure. Corporate bylaws operate within stricter statutory requirements. See Operating Agreement vs Bylaws.
How much does it cost to have a lawyer draft an operating agreement?+
$500 to $2,000 depending on complexity and location. Single-member agreements are simpler ($500 to $800). Multi-member agreements with unequal splits, complex profit-sharing, or significant assets run $1,000 to $2,000 or more. The drafting tool on this page is free and produces a structured outline an attorney can review for a fraction of full drafting cost (typically $200 to $400 for a review pass).
