IOLTA compliance has a reputation for being complicated. In practice, it rests on a small set of rules that have not changed much in decades, and the cases that end in discipline usually involve the same recurring errors. For a personal injury firm, the exposure is higher than average, because settlement money flows through the trust account constantly and often has to be split among the client, the firm, and one or more lienholders. This guide lays out the core rules, the mistakes that most often draw a bar's attention, and what happens when an account is audited. It is written for the solo or small-firm PI attorney who handles client money directly.
Everything below deals with the obligations themselves. If you are also weighing software to help enforce these rules day to day, our guide to trust accounting and IOLTA software for PI firms covers that side.
What IOLTA is, and why PI firms touch it constantly
IOLTA, Interest on Lawyers' Trust Accounts, pools nominal or short-term client funds that cannot practically earn net interest for the client, and forwards the interest to a state program that funds civil legal services for people who cannot afford a lawyer. The concept dates to the early 1980s, following a change in federal banking law, and IOLTA programs now operate in all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands.
The duty to keep client money separate is older and broader than IOLTA itself. ABA Model Rule 1.15 requires a lawyer to hold client and third-party property separate from the lawyer's own property, in a separate account. Every state has its own version of that rule. For a PI practice, the funds that land in trust are constant: unearned retainers, settlement payments, and money owed to medical lienholders or for subrogation. The volume and the multi-party nature of those funds are what make trust accounting a live compliance issue rather than a once-a-year chore.
The core rules every PI firm has to follow
State rules vary in their details, but the backbone is consistent across jurisdictions. These are the obligations a bar examiner expects to see satisfied.
Keep client funds separate, and never commingle
Rule 1.15 allows a lawyer to keep only enough of the lawyer's own money in the trust account to cover bank service charges. Earned fees belong in the operating account. Advance fees and expenses go into trust and come out only as they are earned or incurred. Mixing the two directions, leaving earned fees in trust or paying firm costs from it, is the classic commingling violation.
Track every client on a separate ledger
A trust account holds many clients' funds at once, so each client needs an individual ledger. North Carolina's rule, for instance, requires a ledger recording receipts and disbursements for each person from whom and for whom funds are received, showing the current balance held for each one. The corollary is strict: a firm can never disburse more for a client than that client's ledger shows, because doing so spends someone else's money.
Reconcile on your state's schedule
Reconciliation is the control that catches errors early. The State Bar of California's client trust accounting handbook describes a three-way reconciliation that ties the trust account journal to the client ledgers and to the bank statement, and all three totals must agree. North Carolina requires that a reconciliation report be prepared at least quarterly, on top of a monthly bank reconciliation, while other states expect the full three-way monthly.
Keep complete records, and bank where overdrafts are reported
The ABA model rule sets a five-year retention period after the representation ends; North Carolina requires at least the six-year period before the most recent fiscal year end. Many states add a structural safeguard: a trust account may be held only at a bank that has agreed to report overdrafts. In Illinois, lawyers may hold trust accounts only at banks that notify the disciplinary authority whenever a trust account is overdrawn or an instrument is presented against insufficient funds.
The mistakes that most often trigger discipline
Trust-account discipline rarely comes from exotic schemes. It comes from a handful of routine errors, each of which breaks one of the rules above. Recognizing them is most of the work of avoiding them.
| Common mistake | Rule it breaks |
|---|---|
| Leaving earned fees in the trust account | No commingling (Rule 1.15) |
| Paying a firm or personal expense from trust | No commingling (Rule 1.15) |
| Disbursing more for a client than that client holds | Per-client ledger, no negative balance |
| Skipping or deferring the monthly reconciliation | Reconciliation requirement |
| Withdrawing a fee before it is earned or a lien is resolved | Advance funds belong to the client |
| Incomplete or missing client ledgers and records | Recordkeeping and retention |
| Holding the account at a non-reporting bank | Overdraft-notification rule |
The throughline is that almost every one of these is caught by two habits: a current per-client ledger and an on-schedule three-way reconciliation. A mistake that a monthly reconciliation would have surfaced becomes a violation only when the reconciliation never happened.
For PI firms, the highest-risk moment is disbursing a settlement. The funds arrive as one number and leave as several: the client's net, the contingency fee, case costs, and lien payments. Withdrawing the fee before the lien math is final, or recording a payment against the wrong client, can quietly leave another client's funds short. Until every piece is reconciled against the correct client ledger, the safest assumption is that all of it still belongs to the client.
How a bar audit actually works
Trust-account audits come from two directions, and it helps to understand both. Some are triggered for cause: a client complaint, a discrepancy, or, very commonly, a bounced trust check. Because banks must report trust-account overdrafts to the disciplinary authority in states like Illinois, an overdraft is not a private problem a firm can quietly fix. The report itself can open an inquiry.
Other audits are random. New Jersey, for example, runs a random audit program whose purpose is to confirm that firms maintain the required records, described as a trust account checkbook, a receipts journal, a disbursements journal, and a trust ledger book with an individual ledger for each client. A firm can be selected without any allegation of wrongdoing. North Carolina's rule likewise makes trust records subject to random audit by the State Bar. The recurring theme is that current, reconciled records are expected to exist at all times, not to be assembled after a request.
Staying audit-ready
Audit readiness is not a special project. It is the byproduct of doing the routine work on schedule, so that the records an examiner asks for already exist. Three habits carry most of the weight.
- Your trust account holds only client and third-party funds, plus the small balance your state allows for bank charges.
- Every client has a current ledger with a running balance, and none is negative.
- You complete a three-way reconciliation on your state's required cadence and keep the report.
- Earned fees move to operating promptly, and advance funds stay in trust until earned.
- Your account is held at a bank that reports overdrafts to your state's disciplinary authority.
- You retain client ledgers, journals, bank statements, and reconciliations for your state's required period.
None of this is unique to personal injury work, but the stakes are higher in a practice where large, multi-party settlement funds move through the account regularly. The discipline that protects the firm is the same discipline that protects the client's money: keep it separate, track it per client, reconcile it on schedule, and keep the records.
Built for the claim-valuation side of a personal injury practice.
Trust accounting keeps a firm compliant. Claim valuation is where a PI firm decides what a case is worth and how to move it. Insurance Intelligence Pro, in development at Appalanche, is a claim-valuation-intelligence platform for personal injury attorneys, built by a team that understands the operational realities of running a PI practice. It is not trust accounting or IOLTA software. See what it does and follow its progress.

Is IOLTA participation mandatory?
It depends on the state. IOLTA programs operate in all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands, but the participation rule differs: some states make it mandatory, some use an opt-out model, and a few are voluntary. What is consistent everywhere is the underlying duty to keep client and third-party funds in a separate trust account. Confirm your own state bar's specific IOLTA rule rather than assuming the model that applies elsewhere.
What is the most common IOLTA compliance mistake?
The recurring problems cluster around a few rules: commingling (leaving earned fees or operating money in trust, or paying firm expenses from it), failing to reconcile on schedule, and letting a single client's ledger go negative by disbursing more than that client holds. Each breaks a specific rule, and each is avoidable with monthly reconciliation and a per-client ledger. Because banks must report trust-account overdrafts to the disciplinary authority in many states, a negative balance is one of the fastest ways a mistake becomes a bar matter.
How often does a law firm have to reconcile its trust account?
The cadence is set by each state. Many states expect a three-way reconciliation monthly, tying the bank balance, the trust ledger control balance, and the total of all client ledgers together. North Carolina, for example, requires a reconciliation report at least quarterly, on top of a monthly bank reconciliation. Confirm your state's required frequency, and treat reconciliation as the routine that catches errors before they become violations.
Can a single bounced trust-account check trigger a bar audit?
It can. In many states, the bank holding a lawyer's trust account must notify the disciplinary authority whenever the account is overdrawn or an instrument is presented against insufficient funds, and that report can prompt an inquiry or audit. Separately, several states run random audit programs that select firms with no allegation of wrongdoing at all. Keeping current, reconciled records is the practical defense in both situations.
How long must a PI firm keep its IOLTA records?
The retention period is set by each state. The ABA Model Rule 1.15 sets a model period of five years after the representation ends, and many states follow that while others differ; North Carolina, for example, requires records covering at least the six-year period preceding the most recent fiscal year end. Keep complete records, including client ledgers, journals, bank statements, and reconciliation reports, for at least your state's required period.
