What Is IOLTA? A Plain-English Guide for New PI Attorneys

You won your first personal injury case. The insurance company wires a $75,000 settlement. Before you think about your fee, the medical lien, or the check to your client, one question matters more than any other: where does that money land first?

The answer is your IOLTA account. If you don't set it up or manage it right, you can be disbarred for a clerical error. This is the guide we wish someone had handed us the week we got sworn in.

What IOLTA Actually Stands For

IOLTA means Interest on Lawyers' Trust Accounts. Every US jurisdiction runs some version of the program, and every attorney who holds client money is required to use one.

Here's the mechanical idea. When you receive money that belongs to someone else — a settlement, a retainer you haven't earned yet, a cost advance — you can't deposit it into your firm's operating account. That would be commingling, and it's one of the fastest ways to lose your license.

Instead, you deposit it into a dedicated trust account at an approved bank. The bank pays interest on those pooled client funds — not to you, and not to the clients, but to the state bar's legal aid foundation. That interest funds civil legal services for people who can't afford lawyers.

That's the "IOLTA" part. You don't earn the interest. You don't owe taxes on it. You're a custodian.

The Two Types of Trust Accounts

Most PI attorneys only need to know about one of these, but it helps to see both.

Pooled IOLTA. One account, many clients. Used for funds that are nominal in amount or held for a short period. Ninety-plus percent of PI settlements flow through a pooled IOLTA.

Individual (non-IOLTA) trust account. A separate, interest-bearing account set up for a single client when the amount is large enough or held long enough that the interest would meaningfully benefit the client. If you settle a $5M case and it's going to sit for six months while liens get resolved, your state bar may require you to open an individual trust account so the client earns the interest.

When in doubt, check your state's specific threshold test. California, for example, uses a cost-benefit analysis; Texas has its own framework.

What Goes Into the IOLTA — and What Never Does

The rule is simple: client funds in, firm funds out. The trick is knowing what counts as which.

Goes in

• •Client settlement proceeds
• •Unearned retainers
• •Advance deposits for case costs (filing fees, expert witnesses, medical records)
• •Funds held for third parties (medical liens, subrogation claims)

Never goes in

• •Earned legal fees
• •Your firm's operating money
• •Personal funds of any partner or associate
• •Money from any source that isn't being held for a client or a third party

The only exception most states allow is a small amount of firm money — often $100 to a few hundred dollars — to cover bank service charges. Anything beyond that is commingling.

The Three-Way Reconciliation (the Thing That Gets People Audited)

Every month, three numbers must match:

• •The bank balance on your IOLTA statement
• •The book balance in your trust account's general ledger
• •The sum of all individual client ledger balances

If all three agree, you pass reconciliation. If they don't — even by a penny — you have a problem that must be investigated and documented.

This is where most violations happen. Not because attorneys are dishonest, but because manual tracking across spreadsheets, bank portals, and case management software is genuinely hard. California's Client Trust Account Protection Program (CTAPP), which began random compliance reviews in September 2025, found that 83% of audited firms had noncompliant three-way reconciliations and 89% had noncompliant client ledgers. These aren't edge cases. They're most firms.

What Commingling Looks Like in Real Life

New PI attorneys often commingle without realizing it. A few common patterns:

• •Depositing the whole settlement into your operating account, then writing checks from there. Wrong. It always goes into IOLTA first.
• •Leaving earned fees in the IOLTA "just in case" you need to make adjustments. Once the fee is earned, it has to move to operating promptly. Delay is a violation.
• •Writing an IOLTA check to yourself for an amount not tied to a specific matter. Every disbursement must be traceable to a client.
• •Using one client's funds to cover a shortfall on another client's matter. This is theft, even if you planned to pay it back.

State Variations You Should Know About

IOLTA rules are set state-by-state. A few examples:

• •California: The 1:1:1 rule (one matter, one ledger, one reconciliation trail), plus CTAPP reporting and random audits as of September 2025.
• •Texas: Quarterly reconciliation minimum, with detailed record-keeping under Disciplinary Rule 1.14.
• •New York: 22 NYCRR Part 1300 governs; record retention is seven years.
• •Florida: Chapter 5 of the Rules Regulating the Florida Bar; specific overdraft reporting requirements.
• •North Carolina: Reportedly began geography-based random trust account audits in January 2026, following California's model.

If you practice in multiple states, you have to follow the stricter rule — not the one you like better.

The Three Mistakes That End Careers

• •Commingling — intentional or accidental.
• •Failing to reconcile, then trying to catch up the week before an audit.
• •Treating IOLTA like a savings account — leaving money parked too long, moving funds between client ledgers, or "borrowing" briefly with the intent to repay.

Every disciplinary case you read about starts with one of those three.

How Modern Tools Change the Math

The reason 83%+ of audited California firms fail reconciliation isn't that attorneys don't care. It's that the job was built for a paper-check era. Bank statements arrive once a month. Case management software doesn't always talk to the bank. Paralegals reconcile in Excel.

Modern disbursement platforms — Disbo included — automate the three-way reconciliation in real time. Every matter has its own ledger. Every payment is matter-aware, payee-verified, and journal-logged the moment it leaves the account. When your state bar sends an audit notice, you export the certified reconciliation instead of spending a weekend assembling one.

Whether you use Disbo or build your own system, the principle is the same: trust accounting is too important to do by hand.
