A Plain-English Guide to Forming an LLC in the First State
The limited liability company is Delaware's most popular entity by far. Here is what actually happens when you file one.

The limited liability company has become the default vehicle for small businesses, real-estate deals, and holding structures alike, and Delaware files more of them than any other kind of entity. Forming one is deceptively simple, but a few decisions made at the start shape everything that follows.
The mechanics are straightforward. You choose a name, appoint a registered agent, and file a short certificate of formation with the Division of Corporations, paying a modest fee. Within a day or two — faster if you pay for expedited service — the state returns a stamped certificate, and the entity legally exists.
The document that matters most, though, never touches the state's files. The operating agreement, a private contract among the members, governs how the LLC is managed, how profits are split, and what happens when someone wants out. Delaware law gives members enormous freedom to write their own rules here, which is precisely why sophisticated parties favor the state.
Skipping the operating agreement is the most common and most expensive mistake. Without one, a dispute among members gets resolved by default statutory rules that may bear no resemblance to what anyone intended.
