IOLTA Rules by State / California

California IOLTA Trust Account Rules

A Guide for Attorneys

Administered by State Bar of California

Who Must Maintain an IOLTA Account?

Any attorney licensed in California who receives client funds — whether retainers, settlement proceeds, real estate closing funds, or court awards awaiting disbursement — is generally required to deposit those funds into a designated IOLTA trust account. The account must be maintained at a qualified financial institution that has agreed to remit interest to State Bar of California. Client funds must remain completely separate from the firm's operating accounts at all times.

Small or short-term client funds that would not earn net interest for the client go into the IOLTA account, where the pooled interest is directed to legal aid and bar foundation programs. Larger or longer-term funds that would earn meaningful interest for a specific client should be placed in a separate interest-bearing account for that client's benefit — not in the pooled IOLTA account.

Reconciliation Requirements

California requires monthly three-way reconciliation of your IOLTAtrust account. Three-way reconciliation means verifying that three figures agree: your adjusted bank statement balance, your check register (book) balance, and the sum of all individual client sub-ledger balances. All three must match — it is not sufficient for the bank balance and book balance to agree if the per-client ledgers don't add up to the same total.

California requires reconciliations to be prepared in writing and signed. A verbal or informal reconciliation does not satisfy the rule. The signed reconciliation report must be retained in your files along with the supporting bank statements.

If a discrepancy is found, it must be identified and corrected. Completing the reconciliation and leaving a known discrepancy unresolved is itself a violation. Common causes of discrepancies include transposed amounts, disbursements posted to the wrong client matter, uncleared checks not properly tracked, and bank fees that were not recorded.

Record Retention

California requires attorneys to retain trust account records for a minimum of 5 years. Records that must be kept include bank statements, canceled checks or check images, deposit slips, reconciliation reports, and the client ledger showing each transaction for every client matter.

Many attorneys retain records longer than the 5-year minimum as a matter of professional caution — bar complaints and civil malpractice claims can sometimes surface years after a matter closes. Electronic records are generally acceptable provided they are complete and accessible.

Overdraft Notification

California requires participating financial institutions to notify the state bar if any check or other instrument drawn on a IOLTA account is presented against insufficient funds — regardless of whether the bank honors or returns the item. This means even a momentary overdraft that is immediately corrected will trigger a bar notification and likely a follow-up inquiry. Maintaining accurate real-time records and never disbursing more than the available balance is essential.

Annual Registration

California requires attorneys to annually register their IOLTA trust accounts with the state bar or IOLTA program. This typically involves certifying the account details, the financial institution, and compliance with the trust accounting rules. Failure to register can itself be a disciplinary violation, separate from any substantive accounting error.

Audit Requirements

California operates an active random trust account audit program. Any attorney maintaining a IOLTA account may be selected for examination at any time, without a specific complaint or trigger. Attorneys selected for audit are typically required to produce bank statements, reconciliation reports, client ledgers, and check copies for the period under review.

When a California bar examiner reviews a trust account, they will typically request monthly reconciliation reports for the past 12–36 months, bank statements for the same period, a complete transaction ledger, and individual client sub-ledgers. The examiner may select specific client matters at random and trace every transaction from opening to close. If your sub-ledgers reconcile to the bank balance and your reconciliations are current and signed, the examination is typically straightforward.

Unclaimed Funds and Escheatment

Client funds held in your IOLTA trust account that remain unclaimed for 3 years may be subject to California's unclaimed property (escheatment) laws. When a client matter closes with a remaining balance and you cannot locate the client after documented good-faith attempts, the remaining funds must typically be remitted to the state. The specific procedures — including required notice to the client, the waiting period, and the remittance process — are governed by California's unclaimed property statutes. Failing to remit escheated funds can itself be a separate legal and ethical violation.

How IOLTATrusts Handles California Requirements

IOLTATrusts is purpose-built for the exact requirements that California imposes on attorney trust accounts:

• ✓Automatic monthly reconciliation — generates your three-way reconciliation report in one click, ready to sign and file.
• ✓Per-client sub-ledgers — every transaction is posted to a specific client matter; the sum always reconciles to your total account balance.
• ✓Negative balance prevention — the system blocks any disbursement that would take a client's ledger below zero, preventing the most common compliance failure.
• ✓Period locking — completed reconciliation periods are locked so no one can alter historical records retroactively.
• ✓Immutable audit trail — every transaction, edit, and deletion is logged with a timestamp and user ID.
• ✓One-click audit report — bundles reconciliation history, client ledgers, and transaction records into a print-ready PDF for bar examinations.
• ✓Always audit-ready — because California has an active random audit program, your records need to be complete at all times, not just at year-end. IOLTATrusts keeps them current automatically.
