What is an LLC operating agreement?

An LLC operating agreement is the internal document that spells out how the LLC is owned, managed, and unwound. It is to an LLC what a partnership agreement is to a partnership, or bylaws are to a corporation. In most states it is not filed with the state — it lives with the company’s records — but it controls what happens inside the business when the formation documents run out.

The clauses that matter most cover ownership percentages, voting rights (by ownership share, per capita, or a weighted formula), how profits and losses are allocated, and whether the LLC is member-managed or manager-managed. Buy-sell and transfer provisions matter just as much: they define what happens when a member leaves, dies, or becomes disabled, and they usually give the remaining members a right of first refusal so the LLC is not forced to accept an unwanted owner such as an ex-spouse or a creditor.

Even for a single-member LLC, a short operating agreement is worth having. It keeps the business’s separate identity visible — one of the factors courts weigh when deciding whether to protect the owners’ personal liability — and it satisfies the banks and future investors who typically will not work with an LLC without one. Writing the answers down while everyone is friendly is far cheaper than settling them later.
