The Partnership Agreement for Your New Mexico LLP

It helps to be clear on the difference between two documents that partners sometimes conflate. The Statement of Qualification is the public filing you submit to the New Mexico Secretary of State to register the partnership as an LLP. It is short, it is public, and it establishes the entity and its liability shield. The partnership agreement is the private internal contract among the partners that governs how the business actually runs. You never file it with the state, and it stays out of the public record.

For an LLP, the partnership agreement is the equivalent of what an LLC calls an operating agreement — the internal rulebook. Because a partnership is, by nature, a relationship among people, this agreement is arguably even more important for an LLP than an operating agreement is for a single-member LLC. There is no such thing as a one-person partnership, so there are always at least two sets of interests to reconcile, and the agreement is where you reconcile them in advance instead of in a dispute.

The liability shield and the partnership agreement do different jobs, and understanding how they interact clears up a common misconception.

What the shield does

Registering the Statement of Qualification gives the LLP its shield against vicarious liability — it keeps each partner from being personally responsible for the negligence and misconduct of the other partners. That protection comes from the state registration, not from the partnership agreement. You do not draft your way into the shield; you file your way into it.

What the agreement does

The partnership agreement governs the internal economics and governance: who owns what, how profits are split, who decides what, and what happens when a partner leaves. It does not create the liability shield, but it does two things that reinforce it. First, a partnership that operates by a clear written agreement, keeps proper records, and respects its own structure looks and behaves like the distinct entity it claims to be — which matters if anyone ever challenges the shield. Second, the agreement can allocate responsibilities and indemnities among the partners so that when a claim does hit one partner, the internal consequences are already worked out. The shield protects partners from each other's liability to the outside world; the agreement handles what happens among the partners themselves.

A thorough partnership agreement anticipates the situations that break up partnerships and answers them in advance. The core provisions:

Partners, capital, and ownership

• Who the partners are and each partner's ownership or profit interest
• What each partner contributed at formation — cash, property, services — and how those contributions are valued
• Whether and when partners must contribute additional capital

Money — profits, losses, and draws

• How profits and losses are allocated among the partners, which does not have to be equal or match capital contributions
• When and how partners take draws or distributions
• How the partnership handles a shortfall or a capital call

Management and decisions

• How the partnership is managed day to day and who has authority to bind it
• Which decisions require a simple majority, a supermajority, or unanimity
• How disputes among partners get resolved without dissolving the firm

Changes in the partnership

• How a new partner is admitted, and on what terms
• What happens when a partner wants to leave — the buy-out terms, valuation method, and payment schedule
• What happens on a partner's death, disability, retirement, or loss of a professional license
• Restrictions on transferring a partnership interest to an outsider

Winding down

• The events that trigger dissolution and the vote required to dissolve voluntarily
• How the partnership's affairs are wound up and remaining assets distributed

If a New Mexico partnership never adopts a written agreement, it does not operate in a vacuum — the default provisions of the New Mexico Uniform Partnership Act fill every gap. Those defaults are workable, but they are generic, and they frequently do not match what a particular group of partners would have chosen.

For example, absent an agreement, the statutory defaults may split profits in a way that ignores unequal contributions, give every partner an equal say regardless of investment, or dictate what happens when a partner leaves in a way none of the partners intended. The defaults were written to be a reasonable fallback for partnerships in general, not a tailored fit for yours. Relying on them is a gamble that the state's generic rules happen to align with your specific expectations — and when they do not, the disagreement surfaces at the worst possible time, usually when money or a departure is on the line.

A written agreement lets you override those defaults with terms you actually chose. That is the entire point: the agreement is where the partners decide their own rules instead of accepting the state's.

Because LLPs are so common among licensed professionals, a professional practice's partnership agreement carries a few extra dimensions worth calling out.

Licensing and the loss of a license

The agreement should address what happens if a partner loses or has their professional license suspended — often a mandatory withdrawal, since an unlicensed partner cannot practice. Licensing boards may also impose their own requirements on how professional partnerships are structured, so the agreement should be consistent with those rules.

Client relationships and departures

When a partner leaves a professional practice, clients and matters have to transition. A well-drafted agreement addresses who keeps which clients, how work in progress is handled, and any non-solicitation terms — the questions that turn an amicable departure into a lawsuit when they are not settled in advance.

Buy-in and buy-out

Professional partnerships often admit new partners over time and buy out departing ones. The agreement should specify how a partnership interest is valued, how a buy-in is funded, and how a buy-out is paid — installments, insurance, or otherwise. These terms are the difference between a smooth partner transition and a financially destabilizing one.
