TL;DR — Quick Summary
Illinois attorneys who handle client funds must participate in the IOLTA program under Rule 1.15, placing nominal or short-term funds in a pooled, interest-bearing trust account. Interest goes to the Lawyers Trust Fund of Illinois, not to the lawyer or client. Firms must reconcile at least monthly, keep records for seven years, and report their trust accounts annually through the ARDC registration process.
Overview
Purpose & Function of Illinois IOLTA Accounts
Illinois’s IOLTA program was established by the Illinois Supreme Court in 1983, making it one of the earlier state programs in the country. It resolves a core practical challenge: client funds that are too small in amount or held for too brief a period to generate meaningful interest for individual clients would otherwise sit idle, benefiting no one.
Under the IOLTA framework, those funds are pooled in an interest-bearing account. The bank remits the interest directly to the Lawyers Trust Fund of Illinois (LTF), which distributes grants to civil legal aid organizations, pro bono programs, and access-to-justice initiatives serving low-income residents throughout the state. The LTF has provided tens of millions of dollars to Illinois legal aid programs since the program’s inception.
For attorneys, IOLTA participation is not optional. If you hold client funds in Illinois, you are in the program.
Requirements
Key Requirements of Illinois IOLTA Accounts
Mandatory Participation
All licensed Illinois attorneys handling client or third-party funds must maintain an IOLTA account. No exemptions based on firm size, practice area, or volume of funds handled.
Eligible Institutions
IOLTA funds must be deposited at LTF-approved financial institutions paying comparable interest rates on IOLTA accounts. Always verify an institution's eligibility before opening.
Account Naming
Under Rule 1.15(a), the account must be designated "IOLTA Trust Account" or a similarly clear title — kept entirely distinct from operating or personal funds.
Monthly Reconciliation
A mandatory three-way reconciliation is required at least monthly — comparing the bank balance, trust ledger, and the sum of all individual client ledger balances.
Seven-Year Records
All trust account records must be retained for at least seven years after the conclusion of each matter — longer than most other states require.
Annual ARDC Registration
Under Illinois Supreme Court Rules, attorneys must certify their trust account information annually through the ARDC's online registration portal, even if nothing has changed.
Illinois-Specific Rules
What Makes Illinois's Rules Different from Other States
- Monthly Reconciliation is Mandatory
Illinois Rule 1.15(f) requires all client trust accounts to be formally reconciled at least once per month — not quarterly, as many other states allow. The reconciliation must be a three-way check comparing the adjusted bank balance, the internal trust ledger, and the sum of all individual client sub-ledger balances. All three figures must match exactly at month-end.
- Seven-Year Record Retention
Illinois mandates trust account records be retained for a minimum of seven years after the conclusion of representation — two years longer than the five-year floor used by most states including Louisiana. This extended window significantly expands the record-keeping burden for high-volume practices and firms handling long-running matters.
- Eligible Institution List Managed by LTF
The Lawyers Trust Fund of Illinois maintains its own list of approved IOLTA financial institutions that have entered into agreements to pay comparable rates on IOLTA accounts. Attorneys must confirm their bank appears on this list before opening an account — placing funds at an unapproved institution is a Rule 1.15 violation regardless of intent.
- ARDC Annual Trust Account Certification
Under Illinois Supreme Court Rules, every attorney must certify the status of their trust accounts as part of the Illinois ARDC’s annual registration process. This requirement applies even if an attorney did not hold any client funds during the preceding year, creating a universal affirmative compliance obligation for the entire Illinois bar.
Legal Framework
Core Legal Framework
Illinois’s IOLTA framework is built on a layered regulatory structure that gives trust account obligations both ethical and procedural force.
Rule 1.15 — Safekeeping Property
The foundational duty Illinois lawyers owe when handling client or third-party funds. Client money must be treated as fiduciary property, kept entirely separate from firm assets, and held only at LTF-approved financial institutions. The rule prohibits commingling and makes clear that even inadvertent lapses — including deposits cleared too early or disbursements made before earned — can carry significant disciplinary consequences.
The IOLTA Program (Lawyers Trust Fund of Illinois)
Complements Rule 1.15 and governs the mechanics of the pooled interest program. The LTF defines eligible institutions, sets the comparable rate standard that banks must meet, specifies which fees may be deducted from IOLTA interest before remittance, and serves as the sole beneficiary of all IOLTA interest earned in Illinois. Neither attorneys nor their clients may receive any benefit from IOLTA interest.
Illinois Supreme Court Rules & ARDC Oversight
Tie trust account compliance directly to the annual attorney registration process administered by the Attorney Registration and Disciplinary Commission. The ARDC requires attorneys to certify their trust account status each year and investigates Rule 1.15 violations. Financial institutions approved by the LTF are required to report overdrafts and dishonored transactions on lawyer trust accounts to the ARDC as an early-warning mechanism.

Opening a compliant Illinois IOLTA account is straightforward, but each step carries compliance significance because the account is a fiduciary vehicle for client property.
Ongoing Compliance
Key Requirements for Attorneys Handling Client Funds
Three-Way Reconciliation
Illinois Rule 1.15(f) requires all client trust accounts to be reconciled at least monthly. The reconciliation must compare three numbers: the adjusted bank statement balance, the pooled trust account ledger balance in your accounting system, and the sum of all individual client sub-ledger balances. All three must match exactly at the close of each month.
The supervising attorney remains accountable for reconciliation outcomes even when the task is delegated to staff. Several Illinois disciplinary proceedings have resulted from attorneys delegating trust accounting without maintaining meaningful oversight of the process.
Recordkeeping Standards
Illinois Rule 1.15 requires attorneys to maintain complete, contemporaneous records of all trust account activity for at least seven years after the conclusion of representation for each matter. Required records include:
- Receipt and disbursement journals showing date, amount, payer or payee, and client matter reference for every transaction
- Individual client sub-ledgers showing funds received, disbursements made, and running balances for each matter
- Bank records including monthly statements, deposit slips, and canceled checks or check images
- Supporting documents such as retainer agreements, settlement statements, invoices, and client authorizations
Segregation and Commingling
Client funds must never be deposited into the firm’s operating account. Retainers, settlement proceeds, and any other funds held on behalf of a client go into the trust account until they are earned or properly disbursed. The only firm funds permitted in an Illinois IOLTA account are a nominal amount sufficient to cover bank service charges not already waived by the institution.
Disbursement Rules
Illinois attorneys must never disburse against deposits that have not yet cleared. Funds must be available and confirmed before any check is issued or wire initiated. Attorneys must also ensure that earned fees are transferred out of the trust account promptly once earned — letting firm funds sit in a trust account constitutes commingling even if the intent is conservative.
Oversight & Enforcement
Oversight and Enforcement in Illinois
Lawyers Trust Fund of Illinois (LTF)
Administers the IOLTA program, maintains the list of approved financial institutions, monitors rate comparability compliance, and distributes IOLTA interest to civil legal aid organizations and pro bono programs statewide.
ARDC Registration & Discipline
Investigates trust account violations and administers the annual registration process that includes mandatory trust account certification. The ARDC has authority to impose discipline up to and including disbarment for Rule 1.15 violations.
Automatic Bank Reporting
LTF-approved financial institutions are required to notify the ARDC of any overdraft or dishonored item on a lawyer's trust account. This early-warning system ensures even minor errors surface to regulators immediately, before the problem compounds.
Annual Registration Review
The ARDC's annual registration process includes mandatory trust account certification, giving regulators visibility into every practitioner's trust account status each year — including attorneys who report holding no client funds.
