What is a key rule to form a Limited Liability Company (LLC)?

To form a Limited Liability Company (LLC), a key rule is to properly document the company's intentions and services, which includes detailing the rendering of professional services if applicable. This documentation helps establish the structure and purpose of the LLC, ensuring compliance with state regulations. An LLC typically must file Articles of Organization or Formation with the state; however, simply documenting services also emphasizes adherence to licensing requirements specific to certain professions.

While options like filing articles of association and obtaining a large number of investors might appear relevant, they do not specifically define the necessity for the documentation related to professional services rendered, which is crucial for credibility and legal operation in regulated industries. Forming a sole proprietorship does not apply, as an LLC distinctly requires its own formation steps separate from that structure.
