Forming an LLC with a co-founder in Illinois requires a solid operating agreement. This guide provides key insights and considerations for crafting an agreement that protects your partnership in 2026. An operating agreement is especially critical for co-founders to define roles, responsibilities, and equity splits from the outset.
Without a comprehensive operating agreement, Illinois LLCs default to state law, which may not reflect the co-founders' intentions regarding management, profit distribution, or dissolution. For co-founder pairs, a well-defined operating agreement is essential to prevent future disputes and ensure the business operates smoothly. It clarifies each member's rights and obligations, preventing misunderstandings that can lead to costly legal battles. Remember, Illinois requires an operating agreement but doesn't require it to be filed with the state.
