Without an operating agreement, your Designer LLC in Illinois defaults to state law (the Illinois Limited Liability Company Act). This may not suit your specific needs, especially regarding design IP ownership, profit sharing, and decision-making processes. A well-crafted agreement protects your interests and clarifies member roles.
While Illinois does not require an operating agreement, it is highly recommended for LLCs.
The operating agreement should be kept with the LLC's records and made available to members. Ensure the agreement complies with the Illinois Limited Liability Company Act (805 ILCS 180/).
Clearly defines the members of the LLC and their percentage ownership. This is critical for distributing profits, losses, and voting rights.
Specifies the initial investment made by each member. This can be monetary, in-kind (equipment, software licenses), or sweat equity. Determines how profits and losses are distributed among members. This can be proportional to ownership or based on a different formula.
The most common mistake is using a generic template without customizing it for your specific business structure, industry requirements, and state laws.
