Your LLC operating agreement is one of the most consequential documents your business will ever have, and for too many business owners in Pennsylvania, it either does not exist or has never been reviewed since the day the company was formed. That gap does not become visible until something goes wrong. A partner wants out. A member dies. Two owners disagree on a fundamental decision. When those moments arrive, what is in writing determines what happens next.
What Is an LLC Operating Agreement, and What Does It Actually Govern?
An LLC operating agreement is the internal governing document of a limited liability company. It defines the relationship between members, establishes how decisions are made, sets the terms for how profits and losses are distributed, and outlines what happens when the membership of the company changes.
Under 15 Pa.C.S. Section 8815, the operating agreement governs the relations among the members as members and between the members and the limited liability company, the rights and duties of a person in the capacity of a member or manager, the activities and affairs of the company, and the means and conditions for amending the operating agreement. That is a broad mandate, and it reflects how central this single legal document is to the functioning of any LLC.
If you are still in the process of determining whether an LLC is the right structure for your business, reviewing which business entity fits your situation is a useful first step before addressing the operating agreement.
What Happens to Your LLC Without a Written Operating Agreement?
When members do not have a written business operating agreement, or when the agreement does not address a particular matter, Pennsylvania’s default statutory rules apply. As 15 Pa.C.S. Section 8815(b) states plainly: “To the extent the operating agreement does not provide for a matter described in subsection (a), this title governs the matter.”
That means state law steps in wherever your agreement is silent. And state law was written for every LLC in Pennsylvania, not for yours.
Under 15 Pa.C.S. Section 8847, a Pennsylvania LLC defaults to member-managed unless the operating agreement expressly states otherwise. In a member-managed company, each member has equal rights in the management and conduct of the company’s activities and affairs. A difference arising among members as to a matter in the ordinary course of business may be decided by a majority of the members. But any act outside the ordinary course of business requires the affirmative vote or consent of all members.
If your LLC has two members who contributed different amounts of capital and have different roles in the business, those default rules may not reflect what either of you intended. Without a written operating agreement that addresses those specifics, the statutory defaults control.
How Does an Operating Agreement Prevent Partner Disputes?
The most direct answer is that a well-drafted LLC operating agreement converts expectations into documented agreements. When members know in writing how profits are allocated, who has authority to make which decisions, and what the process is for resolving disagreements, there is far less room for a dispute to take root.
Consider what Section 8847 says about decision-making in a member-managed LLC. A matter in the ordinary course of business can be decided by majority vote. An act outside the ordinary course requires unanimous consent. What constitutes “ordinary course” is not always obvious, and reasonable people will disagree about it. A written operating agreement that defines those categories for your specific business eliminates that ambiguity before it becomes a conflict.
The same logic applies to profit and loss allocations, management authority, the admission of new members, and what happens when a member wants to leave. An operating agreement addresses each of those questions in advance, when everyone is aligned, rather than in the middle of a dispute when they are not. If your business succession planning is also connected to your estate plan, this is one of the reasons why the two plans need to work together.
What Does Pennsylvania Law Say About What Happens When a Member Leaves or Dies?
This is where the absence of a written LLC operating agreement can produce results that are genuinely difficult to reverse.
Under 15 Pa.C.S. Section 8871, a limited liability company is dissolved, and its activities and affairs shall be wound up, upon the passage of 180 consecutive days after the company ceases to have any members, unless, before the end of that period, the transferees owning the rights to receive a majority of distributions consent to admit at least one specified person as a member, and at least one person actually becomes a member in accordance with that consent.
For a single-member LLC, this provision matters directly. If the sole member dies and the estate does not act within that statutory window to name and admit a successor member, the company dissolves. Years of business-building can unravel because the operating agreement did not provide a clear succession path.

For a multi-member LLC, the stakes are different but equally serious. The Pennsylvania Uniform Limited Liability Company Act of 2016 addresses what happens when a member dissociates from the company. Without a written operating agreement providing for an orderly buyout, valuation, or succession, the default rules govern a process that was not designed with your business in mind.
A written LLC operating agreement can address these scenarios directly. It can identify what happens when a member dies, how the remaining members may purchase the departing member’s interest, how that interest will be valued, and what timelines apply. Those provisions are not complicated to draft in advance. They are very complicated to reconstruct after the fact.
Do Single Member LLCs Need an Operating Agreement?
This is a question that comes up consistently, and the answer matters more than many business owners expect.
For single-member LLCs, the operating agreement serves a different but equally important purpose. The absence of other members does not eliminate the need for a governing document. The operating agreement still defines the management structure, the succession plan, and the instructions for what happens if the member becomes incapacitated.
It also documents the separation between the business and its owner. A limited liability company creates a separate legal entity precisely to protect the owner from personal liability for the company’s obligations. That protection depends on treating the business as a genuinely distinct entity, and a written operating agreement is part of how that separation is maintained and demonstrated.
What Should an LLC Operating Agreement Include?
A thorough business operating agreement will address the matters that state law leaves to the members to define. Based on what 15 Pa.C.S. Section 8815 identifies as within the scope of the operating agreement, a complete document will typically cover the following.
The identity of all members and their ownership percentages. How profits and losses are allocated among members. The management structure, including whether the company is member-managed or manager-managed and who has authority to act on behalf of the company. Voting rights and the procedures for making decisions, including any requirements for unanimous consent. How new members may be admitted. What happens when a member wants to exit, becomes incapacitated, or dies. The method for valuing a departing member’s interest and the terms on which it may be purchased. Procedures for resolving disputes among members. Conditions under which the LLC may be dissolved.
An operating agreement can also modify many of the default rules in 15 Pa.C.S. Chapter 88, as long as those modifications do not conflict with the limitations set out in Section 8815(c). That flexibility is the value of having a custom operating agreement drafted for your specific business rather than relying on a generic template that may not reflect what Pennsylvania law requires or permits.
Is a Written Operating Agreement Required Under Pennsylvania Law?
Pennsylvania does not require a written operating agreement as a condition of forming or maintaining an LLC. Under 15 Pa.C.S. Section 8815, an operating agreement may be written, oral, or implied by the conduct of the members.
But the practical difference between a written operating agreement and an oral or implied one is enormous. A written document is clear, enforceable, and can be referenced when disagreements arise. An oral agreement must be reconstructed from memory, and memories diverge. An implied agreement is whatever a court determines the members’ conduct suggests, which may bear no resemblance to what anyone intended.
Pennsylvania law establishes default rules precisely to handle the cases where members chose not to plan in advance. Those defaults are a fallback, not a recommendation.
