Illinois IOLTA Compliance FAQ
What rule governs IOLTA trust accounts in Illinois?
Illinois IOLTA trust accounts are governed by Illinois Rules of Professional Conduct Rule 1.15; Illinois Supreme Court Rule 1.15. The rule sets the requirements for reconciliation frequency, record retention, client ledger maintenance, overdraft notification, and interest remittance to the Illinois IOLTA program.
How often must Illinois attorneys reconcile their IOLTA accounts?
Illinois attorneys have to complete a three-way reconciliation of their IOLTA trust accounts monthly. Three-way reconciliation lines up the bank statement balance, the trust account ledger balance, and the sum of every individual client ledger balance — and all three have to match.
How long must Illinois attorneys retain IOLTA records?
Illinois attorneys have to retain every IOLTA trust account record — bank statements, client ledgers, reconciliation reports, and disbursement documentation — for 7 years under Illinois Rules of Professional Conduct Rule 1.15; Illinois Supreme Court Rule 1.15. Disbo keeps all of it automatically for the required period.
What happens if a Illinois IOLTA account is overdrawn?
Required — bank must notify ARDC (Attorney Registration and Disciplinary Commission). An overdraft notification can trigger a disciplinary review, and the only way to avoid that is to make sure cleared funds are actually in the trust account before any disbursement goes out. Disbo blocks transactions that would create a negative balance before they process.
Where does Illinois IOLTA interest go?
To Lawyers Trust Fund of Illinois (LTF). The funds support civil legal aid programs for low-income residents throughout Illinois. Every IOLTA account has to be at an approved financial institution that forwards the interest to the Illinois IOLTA program.
Referral Fee Rules in Illinois — and How to Actually Pay Them
Trust account compliance and referral fee compliance go hand-in-hand for any Illinois firm that splits fees with co-counsel, accepts case referrals, or pays referring attorneys out of a settlement. The same Illinois Rules of Professional Conduct Rule 1.15; Illinois Supreme Court Rule 1.15 that governs your IOLTA account also dictates how referral fees flow through it — and Illinois Rules of Professional Conduct Rule 1.5(e) adds a separate layer of disclosure, consent, and reasonableness rules on top.
Governing rule: Illinois Rules of Professional Conduct Rule 1.5(e)
The Illinois Referral Fee Standard, in Plain English
Illinois follows the ABA Model Rule with a notable wrinkle: the rule requires the primary lawyer to assume same-firm-level financial and ethical responsibility for the matter when joint responsibility is the basis for the division. The client must agree to the arrangement, including the share each lawyer will receive, and the agreement must be confirmed in writing.
- Client agrees to the fee division and the agreement is confirmed in writing
- Division is in proportion to services or each lawyer assumes joint financial and ethical responsibility
- Total fee is reasonable
- Disclosure of the share each lawyer will receive
Once a Illinois matter resolves and the referral fee is owed, the trust accounting and the actual payment have to line up exactly. Disbo lets you pay attorney referral fees in Illinois directly from the settlement disbursement — with the client consent, fee split, and IOLTA ledger entries documented in one workflow.
The Referral Fee Workflow Most Illinois Firms Get Wrong
Almost every PI and employment firm in Illinois has the same broken referral fee workflow: the obligation lives in a spreadsheet, the disclosure lives in an email, the consent lives in a signed PDF in a shared drive, and the actual payment happens at the bank — completely outside the platform that holds the client funds. That gap is where bar discipline starts and where money gets lost. Here is what the end-to-end flow should look like under Illinois Rules of Professional Conduct Rule 1.5(e), and how Disbo executes it.
- 1
Intake — capture the referring attorney up front
When the matter is opened, the referring attorney's identity, firm, percentage share, and the basis for the division (proportionate services or joint responsibility, depending on what Illinois requires) are recorded as structured fields on the matter — not in a notes box.
- 2
Client disclosure and written consent
Disbo generates the Illinois-specific written disclosure and consent form pre-populated with the participating lawyers, the share each will receive, and the language Illinois Rules of Professional Conduct Rule 1.5(e) requires. The client signs it electronically and the executed form is bound to the matter file.
- 3
Settlement received into IOLTA
When settlement funds hit the IOLTA account, Disbo applies your three-way reconciliation rules under Illinois Rules of Professional Conduct Rule 1.15; Illinois Supreme Court Rule 1.15 and posts the receipt to the client's individual ledger. Nothing is disbursed yet — including the referral fee.
- 4
Fee calculation and split preview
Disbo computes the attorney fee, the referring lawyer's share, the costs to be reimbursed, lien payoffs, and the client's net — all from the agreed percentages. The closing statement is generated automatically in the format your Illinois bar expects.
- 5
Compliance check before disbursement
Before any payment goes out, Disbo verifies the consent is on file, the client's trust balance is sufficient (no negative balance), the total fee is not unconscionable, and any state-specific caps or proportionality requirements are satisfied. If anything fails, the disbursement is blocked.
- 6
One-click payment to the referring attorney
Disbo pays the referring attorney directly out of the IOLTA disbursement by ACH, wire, or printed check — without leaving the platform, logging into your bank, or rekeying the amount. The payment is reconciled against the ledger in real time.
- 7
Audit-ready archive
The signed consent, the fee agreement, the closing statement, the ACH/wire receipt, and the ledger entry are stored together on the matter and retained for 7 years to satisfy Illinois's record retention rule.
Referral Fees by Practice Area in Illinois
Referral fees and co-counsel splits look different depending on the practice area. The underlying ethics rule under Illinois Rules of Professional Conduct Rule 1.5(e) is the same, but the money movement is not. Disbo handles all four of the patterns Illinois firms run into most.
Contingency referral fee from settlement
The classic PI flow. A referring attorney sends you a case, the matter settles, and a percentage of your contingency fee is owed to the referring lawyer. Disbo pays the referring attorney from the IOLTA disbursement, with the Illinois consent and closing statement already attached.
Hybrid contingency + invoiced business clients
Plaintiff-side employment cases are often contingency, but defense-side and advisory work for the same firm is hourly and billed to a business. Disbo lets you invoice businesses directly through the platform — generate the invoice, accept ACH or card payment, deposit operating funds (not IOLTA), and still record any referral or co-counsel split on the same matter.
Multi-firm fee splits with joint responsibility
When two or more {name} firms work a matter together — common in mass tort, complex litigation, and class actions — Disbo records each firm's percentage, the joint responsibility agreement required by Illinois Rules of Professional Conduct Rule 1.5(e), and disburses each firm's share separately at settlement.
Invoice a business for hourly fees
For defense work, in-house counsel arrangements, and business clients on retainer, Disbo lets you invoice the company directly, accept ACH/credit-card payment from the business, deposit it into the operating account (never IOLTA, per Illinois Rules of Professional Conduct Rule 1.15; Illinois Supreme Court Rule 1.15), and route any agreed referral split to the referring attorney from operating — with the same documentation trail as a contingency split.
Invoice Business Clients Through the Same Platform — Even on Employment Disbursements
Most Illinois employment firms run a hybrid book of business: contingency wage-and-hour and discrimination cases on one side, and hourly defense, advisory, severance, and compliance work for businesses on the other. Disbo is built for both. You don't need a second tool to bill the corporate clients — and you don't need a third tool to pay a referring attorney when the case settles.
Issue invoices to businesses from the matter
Generate a branded invoice from any employment matter — defense work for an employer, advisory hours for HR counsel, severance negotiation, an ADA accommodation review. Line-item hourly entries, flat fees, or hybrid arrangements all flow into the same template.
Accept ACH and card payment directly
Businesses pay you online — ACH, credit card, or wire. Funds land in your operating account (not the IOLTA), the invoice is marked paid automatically, and the matter ledger shows the receipt next to the time entries it covered.
Recurring retainers and replenishment
Set up monthly retainers for business clients, automated replenishment when balances dip below a threshold, and credit-card-on-file for predictable corporate billing. The same platform that runs your IOLTA runs your A/R.
Pay the referring attorney from operating
When the business invoice is paid and a referral fee is owed, Disbo pays the referring attorney out of the operating account — not the IOLTA — and applies the same Illinois Rules of Professional Conduct Rule 1.5(e) consent and disclosure documentation you'd use on a contingency split.
One audit trail across IOLTA and operating
Whether the fee was contingent and disbursed from IOLTA, or hourly and invoiced to a business and paid from operating, the matter shows a unified audit trail: engagement letter, fee agreement, referral consent, time entries or settlement, invoice or closing statement, payment receipt, and the referral payment.

Common Illinois Referral Fee Mistakes
- Verbal-only fee splits with no signed client consent — unenforceable and a discipline risk under Illinois Rules of Professional Conduct Rule 1.5(e).
- Cutting the referring attorney's check from a personal account or operating account when the funds came from IOLTA, breaking the money trail.
- Disbursing the referral fee before the settlement check has actually cleared, creating a negative trust balance under Illinois Rules of Professional Conduct Rule 1.15; Illinois Supreme Court Rule 1.15.
- Increasing the total fee charged to the client to absorb the referral split — a per se violation in most jurisdictions.
- Failing to document the basis for the division (proportionate services vs. joint responsibility) when the bar requires one.
- Mixing business-client invoices and IOLTA settlement receipts in the same account because the platform won't separate them.
What Disbo Enforces Automatically
- Blocks any referral fee disbursement when written client consent for that matter is not on file.
- Routes contingency-derived referral payments through IOLTA and business-invoice referral payments through operating — never the wrong direction.
- Refuses any disbursement that would create a negative client balance, no matter who the payee is.
- Locks the total client-charged fee so it can't be inflated to absorb a referral split.
- Prompts you to record proportionate-services or joint-responsibility basis when Illinois requires it.
- Generates the closing statement, payment receipt, and ledger entry as a single signed package retained for 7 years.
One platform, both sides of the ledger
Whether you're disbursing a contingent Illinois settlement out of IOLTA or invoicing a business client for hourly employment defense work, Disbo runs the trust accounting, the invoice, the payment rail, and the referral fee on a single matter — under the same Illinois Rules of Professional Conduct Rule 1.5(e) and Illinois Rules of Professional Conduct Rule 1.15; Illinois Supreme Court Rule 1.15 rule set.
