Illinois LLC operating agreement: skip it, and the Act writes your rules.

No: Illinois law does not require one and the state never files or reviews it. The LLC Act’s default rules govern in its absence, and unwritten understandings are hard to enforce. We draft the written one as part of operating agreement service.

Never: it is a private contract kept with your company records, entirely separate from the annual report due each anniversary month. The Secretary of State has no copy and no role. It matters that it exists, is signed, and can be produced when a bank, a buyer, or a court asks.

The Act’s default rules govern every internal question, ownership, money, exits, deadlock, and any unwritten understandings become contested evidence instead of terms. Every important question gets answered, just not by you. Writing the agreement is how you keep the pen.

Emphatically: the series structure exists in the agreement’s text, series creation, member and asset allocation, separate records, or it does not exist at all when tested. A generic agreement under a series LLC is the most expensive kind of false confidence. We draft series agreements to carry the weight.

Yes: banks and lenders demand one before opening accounts or closing loans, and the agreement is core evidence that the company is an entity distinct from its owner, the separation the LLC exists to create. We draft single-member agreements with exactly that in mind.

Ownership percentages and contributions, management and voting, distributions, transfer and exit rules including death and divorce, deadlock resolution, dissolution terms, and, for series LLCs, the full partition architecture. The clauses you skip are the fights you have later.

Yes. The free builders in our forms library draft single-member, multi-member, and manager-managed agreements live in the browser, and our drafting service builds the custom version: your ownership, management, exits, and, where needed, series structure, reviewed before signing and stored in your document vault. A written agreement costs nothing to adopt, because the state files nothing: there is no state fee at all. When we draft yours, the total is our drafting service fee plus a transaction fee, one-time or included on the plans, itemized on the pricing page before you pay, and the free template builders in our forms library are open to everyone, before signup or after.
