Oregon LLP Partnership Agreement — Why Every LLP Needs One

A partnership agreement is a private contract among the partners of an LLP that governs how the partnership operates. It is not a public document, it is never filed with the Oregon Secretary of State, and it doesn't appear in any state database. It lives in the partnership's own records, and the only people who see it are the partners and anyone they choose to share it with, such as a bank or an attorney.

This is different from the LLP registration, which is the public filing that puts the partnership on Oregon's record and switches on the liability shield. The registration tells the state the partnership exists as an LLP. The partnership agreement tells the partners — and, if it ever comes to it, a court — how the partnership actually works internally.

What the partnership agreement governs

A thorough partnership agreement addresses:

• Partners and ownership: Who the partners are and what interest each holds in the partnership
• Capital contributions: What each partner put in to start, and any obligation to contribute more later
• Profits and losses: How the partnership's economic results are shared among the partners
• Draws and distributions: When and how partners take money out
• Management and authority: Who can make which decisions and bind the partnership
• Voting: How partner votes are structured and what threshold different decisions require
• Admission and withdrawal: How a new partner joins and how a departing partner is bought out
• Dissolution: How the partnership winds down if the partners decide to close it

What it is not

The partnership agreement is not a business plan — it doesn't describe your services, market, or strategy. And it's not a substitute for legal advice on complicated arrangements. If your partnership involves unequal contributions, earn-ins, or outside investment, an attorney should draft the agreement rather than leaving you with a generic template.

The single most important thing that distinguishes an LLP from an ordinary general partnership is the liability shield — and understanding it clarifies why the partnership agreement matters so much.

General partnership vs. LLP

In a plain general partnership, every partner is personally and jointly exposed to the debts and wrongful acts of the business and of every other partner. If one partner's negligence produces a large judgment, a plaintiff can reach the personal assets of all the partners, even those who had nothing to do with it. That exposure is what makes an unregistered general partnership risky for a group of professionals.

By registering as an LLP with the Oregon Secretary of State, the partnership adds a shield. Each partner is protected from personal liability for the negligence and misconduct of the other partners. The liability stays with the partner who caused it and with the partnership, rather than spreading to the innocent partners personally. This vicarious-liability protection is the whole reason a group registers as an LLP instead of operating as a general partnership.

The shield's limits

The shield is not a license to ignore your own conduct. Each partner remains personally responsible for their own negligence and misconduct — the LLP doesn't erase that. Partners also don't escape obligations they personally guarantee. And the shield depends on the LLP being maintained properly: registered, in good standing, and treated as a genuine entity with its own finances. The partnership agreement supports that by documenting that the partners run a real, governed business rather than a loose arrangement.

If your LLP has no partnership agreement, Oregon's partnership statute (Chapter 67 of the Oregon Revised Statutes) supplies default rules. Those defaults fill every gap you didn't address — and they frequently don't match what the partners would have chosen.

Where the defaults surprise people

• Profit sharing: Absent an agreement, statutory defaults may split profits equally regardless of what each partner contributed. If one partner put in far more capital or brings far more business, an equal split may be the last thing anyone intended.
• Management and votes: Defaults about who can bind the partnership and how decisions are made may not reflect the actual authority the partners meant to grant.
• Departure of a partner: The default consequences when a partner leaves — how they're paid, whether the partnership continues — can be disruptive and expensive compared to a well-drafted buyout provision.
• Adding partners: Defaults may not give you the control you want over who joins the partnership.

A written partnership agreement overrides these defaults with the terms the partners actually negotiated. That is the core reason to have one: not because the state requires it, but because the alternative is letting a statute make decisions the partners should be making for themselves.

A good agreement anticipates the situations that strain partnerships — money, decisions, and departures — and resolves them in advance, while everyone is on good terms.

Core provisions to include

• Capital accounts: Each partner's initial contribution and how additional contributions are handled
• Profit and loss allocation: The exact formula for sharing results, which need not be equal
• Distribution policy: When cash is distributed, in what priority, and how draws are treated
• Decision-making: Which matters any partner can decide alone, which require a vote, and the threshold for each
• Partner duties and time commitment: What each partner is expected to contribute in work, not just capital
• Admission of new partners: The process and approval required to bring someone in
• Withdrawal, retirement, and death: How a departing partner's interest is valued and paid, and whether the partnership continues
• Dispute resolution: How disagreements are handled — mediation or arbitration clauses can save a partnership from a courthouse
• Dissolution and wind-up: The process and priorities if the partners decide to close

Keep it current

A partnership agreement isn't a one-time document. As partners join or leave, contributions change, or the business evolves, revisit and amend it. An agreement that reflects a partnership as it was five years ago can be as problematic as having none at all. Review it whenever the partnership's composition or economics shift.

Every LLP should have a written partnership agreement in place before it starts operating — ideally by the time the registration is filed and money starts moving.

Where to get one

For a straightforward partnership with equal partners and simple terms, a well-drafted template that the partners complete carefully can work. For anything more complicated — unequal contributions, differing roles, investors, professional-practice considerations — hire an Oregon business attorney to draft it. The cost of good drafting is small compared to the cost of an ambiguous agreement when partners later disagree.

What Mainstay Filing does and doesn't do

We handle the state-facing paperwork — registering your LLP with the Oregon Secretary of State and serving as your registered agent. We do not draft partnership agreements or provide legal advice; that work belongs with an attorney who can tailor the agreement to your partners' arrangement. What we can do is get the entity properly registered and keep it in good standing, so that when your agreement is in place, it sits on top of a correctly formed LLP. The registration and the agreement work together: the registration gives you the liability shield with the state, and the agreement governs how the partners run the business behind it.
