The Partnership Agreement for a Massachusetts LLP

It helps to be clear about two different documents that people sometimes blur together.

Two documents, two jobs

The LLP registration is filed with the Massachusetts Corporations Division. It is public, and it is what gives the partnership its liability shield — the protection that keeps each partner from being personally liable for the malpractice and misconduct of the others. The partnership agreement is private, is never filed with the state, and governs the internal relationship among the partners: money, management, and exits.

You need both. The registration without a solid agreement leaves the partners exposed to Chapter 108A's default rules for everything the registration does not address. The agreement without the registration is just an ordinary general partnership with no shield. Together they form a complete Massachusetts LLP: protected on the outside, governed clearly on the inside.

Massachusetts partnerships are governed by the Uniform Partnership Act, Chapter 108A of the General Laws. When partners do not write their own rules, that statute supplies defaults — and the defaults are blunt instruments that rarely fit a real firm.

The default rules that surprise people

• Profits split equally. By default, partners share profits equally regardless of who contributed more capital, brought in more clients, or does more of the work. If your firm's economics are uneven — and most are — equal splits are almost never what the partners actually intend.
• Equal management voice. Each partner has an equal say in ordinary business decisions by default, no matter their stake or seniority.
• Broad authority to bind. Absent a written limit, a partner can generally bind the partnership, which is a lot of trust to leave to a default.

A written partnership agreement overrides these defaults with terms the partners choose deliberately. That is the entire point of having one: to replace one-size-fits-all statutory rules with the arrangement your firm actually agreed to.

A thorough partnership agreement addresses the questions that predictably cause conflict, ideally before there is any conflict to resolve.

The economics

• Capital contributions: what each partner put in, in cash or in kind, and any obligation to contribute more later
• Profit, loss, and draw allocation: how the firm's economics are divided, and how and when partners take draws
• Distributions: the timing and priority of cash distributions to partners

Management and decision-making

• Authority: who runs day-to-day operations and what any managing partner can decide alone
• Voting: which decisions require a simple majority, a supermajority, or unanimity, and how votes are weighted
• Signing authority: who can bind the partnership on contracts, leases, and loans

Changes in the partnership

• Admitting new partners: the process and the vote required to bring someone in
• Withdrawal and retirement: how a partner gives notice and exits
• Death or disability: what happens to a partner's interest and role
• Buyout terms: how a departing or deceased partner's interest is valued and paid out — often the single most contested topic when it is left undefined
• Expulsion: the grounds and process, if any, for removing a partner

Ending the firm

• Dispute resolution: how disagreements are handled, including mediation or arbitration if the partners want it
• Dissolution and wind-up: when and how the firm can be wound up and its assets distributed

The task note for this page is worth stating plainly: the liability shield is what distinguishes a Massachusetts LLP from a plain general partnership. That shield comes from the registration and from keeping it in good standing. The partnership agreement supports the shield in a couple of important ways.

Reinforcing the entity

Courts and counterparties take a firm more seriously as a genuine, well-run entity when it operates under a clear governing document, keeps its own finances, and follows its own rules. An agreement that documents contributions, distributions, and decision-making reinforces that the LLP is a real, distinct business — not partners casually sharing money — which supports treating the entity, and its shield, as legitimate.

Provisions that protect the shield indirectly

A good agreement can require that the firm carry professional liability insurance, that it keep its state registration and resident agent current, and that partnership funds stay separate from personal funds. None of these is the shield itself, but each helps ensure the conditions the shield depends on are actually maintained. The agreement, in other words, is where the partners commit to doing the things that keep the protection alive.

Massachusetts LLPs are disproportionately professional practices — law firms, accounting firms, architecture and engineering practices, medical and dental groups. These firms have particular reasons to invest in a strong agreement.

Professional practices deal with client trust accounts or retainers, profession-specific rules on fee splitting and firm governance, partner compensation formulas that can be genuinely complicated, and the near-certainty that partners will eventually retire, die, or move on and need to be bought out. A generic template rarely handles these well. Many professional firms have their agreement drafted or reviewed by an attorney who knows both partnership law and the specific rules of the profession, precisely because the stakes of getting the buyout and governance provisions wrong are high. The agreement is not boilerplate to sign and forget — it is the operating constitution of the firm.

Revisit it as the firm changes

A partnership agreement is not a document you sign once and file away forever. As partners are added, as compensation arrangements evolve, and as the firm grows, the agreement should be revisited so it still reflects reality. An agreement that describes a two-partner firm as it existed years ago is not much help when a five-partner firm hits a dispute. Build in a periodic review — many firms look at it when a new partner is admitted anyway, which is a natural moment — so the governing document keeps pace with the partnership it governs rather than drifting out of date and becoming a source of conflict instead of a way to resolve it.
