Can Illinois Lawyers Share Referral Fees?
Yes, with conditions — and Illinois is notably friendlier to referral arrangements than most joint-responsibility states. Division is permitted if proportional to services, or if the referring lawyer assumes joint financial responsibility, with written disclosure and client consent.
What IL requires
- Division proportional to services performed, OR each lawyer assumes joint financial responsibility for the representation
- Client agrees to the arrangement, including the share each lawyer will receive, confirmed in writing
- Total fee must be reasonable
How Illinois compares to California
Illinois occupies a middle ground: unlike California it requires joint financial responsibility for referral-based splits, but "financial" responsibility (a guarantee-like commitment) is a narrower undertaking than the full joint representation some states demand. For the full California treatment, see our CRPC 1.5.1 guide — or estimate a split with the referral fee calculator.
Frequently asked questions
What is "joint financial responsibility" in Illinois?
The referring lawyer accepts financial responsibility for the representation — commonly understood as legal accountability to the client comparable to a partner's — without necessarily performing legal work on the matter.
Must the client know the exact split in Illinois?
Yes. The client must agree to the arrangement including the share each lawyer will receive, and the agreement must be confirmed in writing.
Is a referral fee enforceable without the writing in Illinois?
Courts have repeatedly refused to enforce divisions that fail Rule 1.5(e)'s writing and consent requirements. Paper first, refer second.
