A limited liability company is a business formed by an organizer who may, but need not be a member. It is a business entity separate from its members and liability is limited to the financial contribution made by the member. The members are the owners of the company. The management of the company is carried out by its members, unless the Articles of Organization provide for management by managers. Governance is set forth by the Articles of Organization or operating agreement.

An important feature of LLCs is "limited liability," which means that all LLC owners are protected from personal liability for business debts and claims. This means that if the business itself can't pay a creditor—such as a supplier, a lender, or a landlord—the creditor cannot legally come after an LLC member's house, car, or other personal possessions. Because only LLC assets are used to pay off business debts, LLC owners stand to lose only the money that they've invested in the LLC.
