The Limited Partnership Agreement for a Washington LP

The limited partnership agreement is the private contract among the partners that governs how the LP runs. It is the LP's counterpart to an LLC's operating agreement or a corporation's bylaws — the internal rulebook. Washington does not require you to file it with the state, and you should not: it stays confidential among the partners.

Why it carries extra weight in an LP

In a limited partnership, the agreement does something structurally important that it does not have to do in other entities: it defines and protects the line between the general partners, who manage and are personally liable, and the limited partners, who invest passively and enjoy capped liability. Because a limited partner who crosses into management can lose their liability shield, the agreement is where you carefully define what each class of partner may and may not do. Get that wrong, and the whole reason for choosing an LP can unravel.

The relationship to RCW 25.10

The Washington Uniform Limited Partnership Act sets default rules for partnerships. Your agreement can override many of those defaults to fit your deal. Where your agreement is silent, the statute fills the gap — which is exactly why a thorough agreement matters: it is how you keep control of your own arrangement instead of inheriting whatever the statute provides.

One of the agreement's core jobs is to record what each partner is putting in and what they get for it.

What to spell out

• Initial contributions. What each general and limited partner contributes at formation — cash, property, services, or a promise to contribute — and the agreed value of non-cash contributions.
• Ownership and profit interests. Each partner's percentage interest, which drives profit sharing and, often, voting where limited partners have a vote.
• Future contribution obligations. Whether partners can be called on to contribute more later (capital calls), on what terms, and what happens to a partner who cannot or will not meet a call.
• Capital accounts. How each partner's capital account is tracked over time as contributions, allocations, and distributions accrue.

For an LP raising money from limited partners, this section is central: the limited partners' contributions are the reason the entity exists, and clarity here prevents disputes when the money starts flowing back out.

How economic returns move through the partnership is one of the most negotiated parts of any LP agreement, and it does not have to be simple or proportional.

Key provisions

• Profit and loss allocation. How gains and losses are divided among partners. This need not match ownership percentages — LPs frequently use tiered or preferred allocations, especially to give limited partners a preferred return before the general partner shares in the upside.
• Distributions. When and how cash is actually paid out, which is distinct from how profit is allocated on paper. The agreement sets the timing, priority, and conditions.
• Preferred returns and waterfalls. Many investment-oriented LPs give limited partners a preferred return first, then a "waterfall" that splits remaining cash between limited and general partners at defined tiers. If your LP pools investor capital, this structure is often the heart of the deal.
• Tax allocations. How tax items flow through on the K-1s, coordinated with the economic allocations so the two stay consistent.

This is the section where an attorney and accountant earn their keep, because the interaction between economic and tax allocations is genuinely technical.

This is the section that makes an LP an LP. It defines who controls the business and, just as importantly, how limited partners stay passive without becoming powerless.

General partner authority

• The scope of the general partner's management power — what they can do unilaterally on behalf of the partnership.
• Limits and reserved matters — major decisions (selling the business, admitting new partners, taking on large debt) that may require limited-partner consent even though limited partners do not manage day-to-day.
• Standard of conduct and indemnification — the general partner's duties to the partnership and when the partnership indemnifies them.

Keeping limited partners protected

The agreement should carefully preserve the limited partners' passive status. Washington law gives limited partners safe harbors — certain actions, like voting on fundamental matters, consulting with the general partner, or approving specific major decisions, generally do not count as "participating in control" and so do not jeopardize their liability shield. A good agreement leans on those safe harbors: it gives limited partners meaningful protections and voice on big decisions while keeping them out of the operational control that would put their liability cap at risk. This balance is the whole craft of drafting an LP agreement.

An LP outlives individual partners' involvement only if the agreement plans for exits. These provisions determine what happens when someone wants in or out.

What to address

• Transfer of interests. Whether and how a partner can sell or assign their interest, any rights of first refusal, and whether an assignee becomes a full partner or only receives economic rights. Limited-partner interests are often more freely transferable than the general partner's central role.
• Admission of new partners. The process and approvals for bringing in additional limited partners or a new general partner.
• Withdrawal of a partner. What happens when a partner leaves — buyout terms, valuation method, and payment timing. Because the LP must have a general partner, the agreement should plan for succession if the sole general partner withdraws, dies, or becomes bankrupt, so the partnership does not dissolve by accident.
• Dissolution and winding up. The events that trigger dissolution and how the LP winds down, settles debts, and distributes remaining assets. Aligning these terms with the actual wind-up process keeps a closure orderly.

Without these provisions, RCW 25.10's defaults control — and the defaults may force a dissolution or a result the partners never wanted. Planning exits in advance is far easier than litigating them later.

Because Washington does not require the agreement to be filed — or even to exist in writing — it is tempting to operate on a handshake, especially among partners who trust each other. That is a mistake, and here is the concrete reason.

What "no agreement" actually means

Operating without a written limited partnership agreement does not mean you have no rules. It means the statutory defaults in RCW 25.10 become your rules — on contributions, allocations, distributions, voting, transfers, and dissolution. Those defaults were written to cover the average case, not your deal, and they frequently allocate rights and money differently than the partners intended.

For a limited partnership specifically, the risks of going without are sharpest around liability. The agreement is where you carefully preserve the limited partners' passive role and protect their liability shield; without it, the lines blur, and a limited partner who steps in to "help" can inadvertently forfeit their protection. The general partners, meanwhile, carry personal liability and want the clarity a written agreement provides about their authority and duties.

A note on scope

Mainstay Filing prepares and files your Certificate of Limited Partnership — the state-facing document. We do not draft your limited partnership agreement, because it is a legal document that should reflect your specific deal and, for anything beyond the simplest arrangement, be prepared or reviewed by an attorney. Investing in a well-drafted agreement up front is cheap compared to the cost of resolving a dispute — or a lost liability shield — after the fact.
