If you’re starting a business in Illinois, forming a Limited Liability Company (LLC) is often the first step. But one of the most important documents many business owners overlook is the Operating Agreement.
While Illinois law does not require LLCs to have an Operating Agreement, having one is critical for protecting your company and avoiding disputes. Without it, your business will default to Illinois’ LLC Act rules—which may not align with how you want your company to operate.
At Storm & Piscopo, P.C., our Illinois business attorneys draft customized Operating Agreements that protect owners, clarify responsibilities, and help prevent costly legal battles. Here’s what every Illinois LLC Operating Agreement should include.
1. Basic Company Details
Every Operating Agreement should begin with the fundamentals:
– LLC name (as registered with the Illinois Secretary of State)
– Principal place of business
– Purpose of the LLC
– Duration of the company (usually “perpetual”)
This ensures your agreement matches state records and avoids confusion.
2. Ownership and Membership Interests
A clear ownership structure reduces the risk of disputes. Include:
– Names of all members (owners)
– Each member’s percentage of ownership
– Initial capital contributions (cash, property, or services)
3. Management Structure (Member-Managed vs. Manager-Managed) Illinois LLCs can be either:
– Member-managed: All members participate in decision-making and daily operations.
– Manager-managed: Members appoint one or more managers to run the business.
Your Operating Agreement should specify the structure, define roles, and establish how decisions will be made.
4. Profit, Loss, and Distribution Rules
Key financial provisions include:
– How profits and losses are allocated among members
– When distributions will be made
– Rules for reinvestment of business earnings
Without clarity, money disputes can quickly sour business relationships.
5. Meetings, Voting, and Decision-Making
Outline how your LLC makes important decisions:
– Frequency of meetings (if any)
– Quorum requirements
– Voting rules (majority vs. supermajority) for actions such as admitting new members or dissolving the LLC
6. Adding or Removing Members
Membership changes are inevitable. Your agreement should cover:
– Admission of new members
– Buyout provisions when a member withdraws, retires, or passes away
– Restrictions on selling or transferring membership interests
7. Dissolution and Winding Up
Protect your business with a clear exit plan:
– Triggers for dissolving the LLC
– How assets and debts will be handled
– Order of distributions when winding up
8. Dispute Resolution
Many Illinois LLCs include a dispute resolution clause requiring mediation or arbitration before going to court. This can save time, money, and preserve business relationships.
9. Other Provisions
Finally, consider adding:
– Confidentiality and non-compete agreements
– Choice of Illinois law as the governing authority
– Procedures for amending the Operating Agreement
