The New Hampshire LLC Operating Agreement Explained

An operating agreement is a written contract among the members of an LLC (or, for a single-member LLC, a declaration by the sole member) that sets the rules for how the company is owned and run. It's the LLC equivalent of a corporation's bylaws and shareholder agreement rolled into one.

It's private and never filed

Unlike your Certificate of Formation, the operating agreement is not filed with the New Hampshire Secretary of State and never becomes public. It lives in your company records. That privacy is a feature — the sensitive details of ownership, money, and control stay between the members.

It overrides the state defaults

New Hampshire's LLC Act (RSA 304-C) supplies default rules for LLCs that don't address a given issue themselves. Those defaults are generic and often don't match what the owners actually want. A well-drafted operating agreement replaces the defaults with your own terms — how profits split, how big decisions get made, what happens if a member dies or wants to leave. Without one, you're stuck with whatever the statute says, and that can produce outcomes no one intended.

A thorough operating agreement anticipates the questions that come up over a company's life and answers them in advance, while everyone still gets along.

Ownership and contributions

• Membership interests — who the members are and what percentage each owns.
• Capital contributions — what each member contributed at formation (cash, property, services) and whether future contributions can be required.
• Additional capital — what happens if the company needs more money later, and whether a member who doesn't contribute gets diluted.

Money

• Profit and loss allocation — how profits and losses are divided among members. This often tracks ownership percentages but doesn't have to.
• Distributions — when and how cash is paid out to members, and in what priority.

Control

• Management structure — member-managed or manager-managed, and the authority of whoever runs the company.
• Voting rights — whether votes are weighted by ownership or counted per member, and which decisions need a supermajority or unanimity.
• Day-to-day authority — who can sign contracts, spend money, and bind the company.

Change and exit

• Transfer restrictions — whether a member can sell their interest, and any rights of first refusal.
• Buy-sell provisions — what happens when a member dies, becomes disabled, divorces, or wants out, and how their interest is valued and bought out.
• Adding members — the process for bringing in new owners.
• Dissolution — the circumstances under which the LLC winds down and how assets are distributed.

It's a common misconception that a single-member LLC doesn't need an operating agreement because there's no one to agree with. In fact, having one matters even when you're the only owner.

Reinforcing the liability shield

One of the main reasons courts pierce the liability protection of a single-member LLC is that the company doesn't look like a genuinely separate entity. An operating agreement is documentary evidence that you treat the LLC as its own thing, with its own rules — one more layer supporting the separation between you and the business that keeps your personal assets protected.

Banks and third parties ask for it

Many banks request an operating agreement when you open a business account, even for a single-member LLC. Lenders, investors, and potential buyers often want to see one too. Having it ready avoids friction at exactly the moments you're trying to move forward.

Planning for the future

Your single-member LLC might not stay single-member. An operating agreement establishes the framework for adding members, and it can specify what happens to the company if something happens to you — succession that otherwise defaults to the statute and possibly probate.

For an LLC with more than one owner, the operating agreement isn't just advisable — it's the single most important document for preventing disputes.

It settles arguments before they happen

Most serious LLC conflicts trace back to something the members never wrote down. Who decided the company would take on debt? How do we value a departing partner's share? What if one member stops contributing but still expects an equal cut? An operating agreement answers these while everyone is aligned, so there's a rule to point to when the relationship is strained.

Without one, the statute decides — often unfairly

If a multi-member LLC has no operating agreement, RSA 304-C's defaults govern. Those defaults might, for example, allocate profits or voting power in a way that doesn't reflect what the members actually agreed to informally. A default rule that splits things evenly can be badly wrong when one member put in most of the money or does most of the work. The operating agreement lets you set terms that match reality.

It protects minority and majority members alike

Good provisions protect a minority owner from being frozen out and protect the majority from being held hostage. Buy-sell terms, transfer restrictions, and clear voting thresholds give everyone predictability about how the company will be run and how they can exit if they need to.

Drafting it

You can use a template as a starting point, but the terms should reflect your specific arrangement — ownership percentages, capital, management, and exit provisions that match what the members actually agreed. For a straightforward single-member LLC, a solid template is often enough. For a multi-member LLC, especially one with unequal contributions, outside investment, or complex arrangements, having an attorney draft or review it is money well spent. Mainstay Filing is a filing service, not a law firm, so for custom legal terms you'll want an attorney.

Signing and storing it

All members should sign the agreement, and each should keep a copy. Store the signed original with your other core company records — your Certificate of Formation, EIN confirmation, and annual report history.

Keeping it current

An operating agreement isn't a set-it-and-forget-it document. Update it when members join or leave, when ownership percentages change, when you switch management structure, or when the way you actually run the company drifts from what's written. An outdated agreement that no longer matches reality is a common source of disputes — the whole point is that it reflects the real deal among the members.
