An Illinois Single-Member LLC Operating Agreement clarifies the goals and policies of a limited liability company owned by only one managing individual within a written form. The state legislature does not specify that this document be recorded to apply for the official foundation of an LLC, although it can serve to enforce the legitimacy of the business further. The owning party can stipulate specifics regarding how the company plans to be maintained for future reference and can instate procedures should additional members obtain ownership of the business down the line.
