An LLC doesn’t have bylaws. Bylaws are the internal governance document for corporations, and the equivalent document for a limited liability company is called an operating agreement. If someone has asked you for your LLC’s bylaws, what they almost certainly want is the operating agreement. It covers the same ground, just under a different name and with far more flexibility than a corporation’s bylaws allow.
Bylaws, Operating Agreement, and Articles of Organization
Three documents get tangled together whenever a new business entity comes up, and keeping them straight makes the rest of this easier.
Corporate bylaws govern a corporation’s internal affairs: board meetings, officer roles, shareholder voting. They exist because corporations are locked into a rigid officer-and-board structure and need rules for operating it.
An LLC operating agreement covers the same territory for an LLC: who owns what, who decides what, how money moves, what happens when someone leaves. LLCs aren’t bound to the corporate structure, so the agreement can be shaped to fit the business rather than the other way around.
The articles of organization (called a certificate of formation or certificate of organization in some states) are the separate document you file with the state to legally create the LLC. They carry only bare-bones information: the company’s name, its registered agent, its address, and whether the LLC will be member-managed or manager-managed. That filing is the public-facing birth certificate. The operating agreement, by contrast, is a private internal document that stays with the company and generally never gets filed with any government office.
What an LLC Operating Agreement Covers
An operating agreement can run long or stay lean, but most include a core set of provisions that keep disputes from becoming lawsuits.
Membership and Ownership
The agreement identifies every member and their ownership percentage. That percentage becomes the baseline for everything else: how profits divide, how much each vote counts, what happens when someone leaves. It should also set out how the LLC admits new members and the process for a member who wants out.
Management Structure
Every LLC is either member-managed or manager-managed. In a member-managed LLC, all owners participate in running the business. In a manager-managed LLC, the members designate one or more managers, who may or may not themselves be owners, to handle operations while the other members stay passive. The operating agreement states which model applies and defines the scope of the manager’s or members’ authority.
Whoever manages the LLC owes fiduciary duties to the company and its members. The duty of loyalty means putting the company’s interests ahead of personal ones and avoiding conflicts. The duty of care means making reasonably informed decisions rather than reckless ones. Most states also recognize an obligation of good faith and fair dealing. These duties can often be modified by the operating agreement, though they typically can’t be eliminated entirely.
Voting and Decision-Making
Not every decision needs the same level of agreement. The operating agreement sets voting thresholds by category. Routine matters might need a simple majority. Bigger moves, like taking on substantial debt or admitting a new member, might require a supermajority or unanimous consent. Voting power is usually proportional to ownership, but the agreement can set it up differently. This section also clarifies who can sign contracts and bind the LLC without a formal vote.
Capital Contributions
Capital contributions are what each member puts in to get the business started. Contributions can be cash, property, or services. The agreement should record each member’s initial contribution and its agreed value, since that record often drives ownership percentages and profit splits.
Equally important is what happens after launch. The agreement should say whether the LLC can issue capital calls requiring members to invest more, and spell out the consequences for a member who doesn’t contribute when called. Common consequences include dilution of the non-contributing member’s stake or treating the unpaid amount as a loan repaid before any profit distributions.
Profit and Loss Distribution
The agreement defines how profits and losses divide among members, and when distributions actually get paid. Members can split in proportion to ownership, or use a special allocation that distributes differently. A member who contributes expertise rather than cash, for instance, might negotiate a larger profit share than ownership alone would give.
This is one area where having an agreement matters most. Without one, most states default to splitting profits equally among all members regardless of how much each person invested. If one member put in $200,000 and another put in $50,000, an equal split probably isn’t what either of them intended.
Transfer of Interest
Transfer restrictions control what happens when a member wants to sell or give away their stake. A right of first refusal lets the other members match any third-party offer before the selling member can close with an outsider. A right of first offer requires the departing member to negotiate with fellow members before shopping the interest outside at all. Either structure keeps control over who ends up owning a piece of the business.
Member Departures
What happens when a member dies, becomes disabled, or wants to leave? Without clear terms, the result in many states gets messy: a deceased member’s heirs may receive only economic rights without management authority, or the LLC may face dissolution under default rules. A buy-sell provision in the operating agreement creates a predetermined mechanism for the remaining members to purchase a departing member’s interest, usually with a stated valuation method and payment timeline.
Dissolution
The agreement should specify what triggers dissolution and how wind-down works. Common triggers include a unanimous vote, a specific date, or events like the departure of a key member. The section covers the order of operations: settling debts first, then distributing remaining assets to members according to their interests. Skipping this provision doesn’t prevent dissolution; it just hands the process to the state’s default rules.
Is an Operating Agreement Legally Required?
Most states don’t require LLCs to have a written operating agreement. A handful do, and in those states the agreement is a required part of forming the LLC even though it still doesn’t get filed with the state.1U.S. Small Business Administration. Basic Information About Operating Agreements
Required or not, operating without an agreement is a gamble that rarely pays off. The operating agreement is one of the key formalities that separates your LLC from a sole proprietorship or general partnership in a court’s eyes.1U.S. Small Business Administration. Basic Information About Operating Agreements If an LLC is treated casually, with commingled funds and skipped governance, a court can pierce the veil and hold members personally liable for company debts. The operating agreement is relatively cheap insurance against that outcome.
Single-member LLCs face this risk most acutely. With no one to negotiate with, it’s tempting to skip the agreement entirely. But a single-member operating agreement documents that the LLC is a separate entity with its own rules, its own finances, and its own governance, which is exactly what courts look for when deciding whether the liability shield holds.
What Happens Without One
When an LLC has no operating agreement, the state’s default LLC statute fills every gap, and those defaults tend to be blunt. Most states assume equal voting rights regardless of investment. Many default to equal profit sharing. Some require unanimous consent for major decisions, which gives any single member veto power over the business. Others let members withdraw at any time without the remaining members’ approval.
These defaults produce outcomes nobody intended. A member who put up 80% of the startup capital gets the same profit share as one who put up 5%. A member who wants to block a decision can hold the company hostage. A member who walks away can trigger a dissolution. The operating agreement replaces these generic rules with arrangements the members actually agreed to.
Adopting and Amending the Agreement
An operating agreement takes effect when every member signs it. The date should be on the document, and each member should keep a fully executed copy alongside the articles of organization and other company records.
Amendments follow whatever process the agreement itself prescribes. Some require unanimous consent; others allow changes with a majority or supermajority vote. If the agreement is silent on amendments, most states default to at least a majority vote, though changes that affect a specific member’s financial obligations or profit allocations may need that member’s individual consent regardless. When an amendment is approved, attach it to the original, have all members sign, and distribute updated copies.
