The Partnership Agreement for a Pennsylvania LLP

A partnership agreement is the internal contract among the partners of your LLP. It is the LLP's counterpart to an LLC's operating agreement: the private document that governs ownership, money, management, and what happens when things change. Pennsylvania does not require you to file it with the state, and it never becomes public — but it is the backbone of how the firm actually runs.

Why it is not optional in practice

Pennsylvania's Uniform Partnership Act supplies default rules for partnerships that have no agreement, or whose agreement is silent on a given point. Those defaults tend toward simple, one-size arrangements — equal profit sharing, equal management rights, straightforward exit rules — that rarely match what real partners intend. If you skip the agreement, you are not avoiding rules; you are accepting the state's defaults by inaction. A written agreement lets you set your own terms instead.

Before getting into the agreement's contents, it is worth being clear about the thing that distinguishes an LLP from an ordinary general partnership: the liability shield. This is the reason the LLP form exists, and the partnership agreement operates against its backdrop.

The problem the shield solves

In a plain general partnership, every partner is personally liable for everything the partnership owes — including claims created by a partner they had no part in supervising. If your partner commits malpractice, your personal assets are exposed even though you did nothing wrong. That joint-and-several exposure is a serious risk, especially for professional firms where one partner's mistake can generate a large claim.

What registration changes

When the partnership registers as an LLP with the Department of State, that changes. A partner in a registered LLP is not personally liable for obligations arising from another partner's negligence, wrongful acts, or misconduct. The shield contains each partner's exposure to their own conduct and their own capital in the firm.

What the shield does not do

The shield has clear limits. It does not protect a partner from liability for their own malpractice. It does not release a partner from a debt they personally guaranteed. And it does not shield the partnership's own assets from its creditors — the firm's obligations remain the firm's obligations. The LLP protects partners from each other's conduct, not the business from its own debts. Understanding these boundaries is why professional firms carry malpractice insurance even inside an LLP.

A thorough partnership agreement anticipates the situations that otherwise become disputes. At a minimum, it should address the following.

Ownership and capital

• Partners and their interests. Who the partners are and how their ownership is expressed — by percentage, by units, or by capital account.
• Capital contributions. What each partner contributed at the start, and whether and how partners can be required to contribute more later.
• Capital accounts. How each partner's account is tracked over time as contributions, allocations, and draws move through it.

Money

• Profit and loss allocation. How the firm's results are divided. This need not be equal, and in many firms it is deliberately not — it may reflect capital, seniority, or productivity.
• Draws and distributions. When and how partners take money out, and any limits during lean periods or wind-down.

Management and decisions

• Authority. Who runs the day-to-day, and what any single partner can commit the firm to without a vote.
• Voting. Which decisions require a majority, a supermajority, or unanimity — admitting a partner, taking on major debt, changing the agreement, dissolving.

The clauses that matter most are usually the ones about change, because that is when partnerships strain. A good agreement handles these before anyone is upset.

Admitting new partners

Spell out how a new partner joins — who must approve, what they contribute, and how existing interests adjust. Professional firms often have a defined partner-track process worth reflecting in the agreement.

Departure, retirement, and death

• Voluntary exit. How a partner gives notice, and how their interest is valued and paid out.
• Buyout terms. The formula or method for valuing a departing partner's stake, and the payment timeline — vague valuation language is a leading cause of partner litigation.
• Death or disability. What happens to a partner's interest, and whether the firm or the remaining partners buy it out.

Dispute resolution

A mechanism — mediation, arbitration, or a defined internal process — for resolving disagreements without immediately heading to court can save a firm from tearing itself apart over a solvable dispute.

Dissolution

The circumstances that wind the firm down, and the order in which obligations are paid and remaining assets distributed. A clear dissolution clause makes an orderly wind-up mechanical instead of contentious.

Because professional practices make up so much of the LLP world, their agreements often carry provisions a general business partnership would not.

Malpractice and insurance

The agreement commonly addresses required malpractice coverage, minimum limits, and how the cost is shared. Since the LLP shield does not cover a partner's own malpractice, insurance is the real protection, and the agreement can make carrying it a condition of partnership.

Client matters and files

For firms that hold client relationships and files, the agreement may address what happens to clients and matters when a partner leaves — subject, always, to the profession's ethical rules, which override anything the partners might prefer.

Board and licensing constraints

Licensing boards impose rules that a private agreement cannot contract around. A well-drafted professional partnership agreement is written to sit comfortably inside those rules rather than against them. This is exactly the kind of drafting where an attorney experienced in your profession earns their fee.

Here is where we are candid about our role. Mainstay Filing handles the state-facing side of your LLP — preparing and submitting the registration that gives your partnership its LLP status and the liability shield, and keeping your compliance current afterward. Getting that registration right is what makes the shield real in the first place.

The partnership agreement itself is a different animal. It is a negotiated legal contract that allocates money, control, and risk among specific people, and it should be drafted or reviewed by an attorney — especially for a professional firm operating under board rules. We are a filing service, not a law firm, and we do not draft your economic terms or resolve disputes between partners. What we do is make sure the entity underneath the agreement is properly registered and stays in good standing, so the shield your agreement relies on is actually in place.
