Tom Girardi allegedly stole more than $18 million from his own clients' trust accounts — money meant for burn victims, widows, and plane crash survivors. When the scandal broke, California's response wasn't just to prosecute Girardi. The state overhauled trust account oversight for every attorney in California, launching the Client Trust Account Protection Program (CTAPP) — annual registration, self-assessments, and mandatory compliance certifications for anyone holding client funds. In July 2023, the State Bar of California administratively suspended more than 1,600 attorneys for failing to comply with the new reporting rules.
Here is the uncomfortable implication: if 1,600 California lawyers could not complete even the basic annual paperwork on their trust accounts, how many are actually performing monthly three-way reconciliation the way their state bars require? The answer — from every bookkeeper who has inherited a law firm's books — is "far fewer than you would think." Trust accounting remains the single most frequent source of attorney discipline in the United States, and the single most effective prevention is a procedure most firms skip, shortcut, or misunderstand: three-way reconciliation.
If you manage a law firm's books — whether you are a managing partner, a solo practitioner, or an office administrator handling the finances — this article walks you through exactly what 3-way reconciliation is, why state bars mandate it, how to perform it every month without fail, and where firms most commonly go wrong. We will cover the workflow, the software, the documentation, and the compliance stakes. Get this right, and you sleep at night. Get it wrong, and your license is at risk.
Three-way reconciliation is the monthly process of confirming that three separate records of your IOLTA (Interest on Lawyers' Trust Account) balance all agree to the penny. The word "three-way" — sometimes written as "3-way reconciliation" — refers to the three independent ledgers that must be compared:
All three numbers must match. Not approximately. Not "close enough." Exactly. If the bank says $142,317.44, your combined trust ledger must show $142,317.44, and the sum of every individual client ledger must equal $142,317.44.
Why three ledgers instead of two? Because a standard bank reconciliation — comparing your books to the bank — only tells you whether the total amount in the account is correct. It cannot tell you whether that money is correctly attributed to the right clients. You could have the right total while still commingling funds, misposting a deposit to the wrong client, or holding money for a client whose matter closed six months ago. The third leg of the reconciliation — the sum of individual client ledgers — is what catches those errors. It is the step that protects clients from one another's mistakes and protects you from disciplinary action.
A healthy IOLTA account has no "float," no attorney money parked in it, and no negative client balances. The three-way reconciliation is the monthly proof that this is true.
The authoritative framework for lawyer trust accounting begins with ABA Model Rule 1.15, "Safekeeping Property," which requires lawyers to hold client funds separate from their own, maintain complete records, and preserve those records for a defined retention period. You can read the rule directly at the ABA's Center for Professional Responsibility. The Model Rule is not itself binding — it is a template — but nearly every state has adopted a version of it, and most have layered on additional requirements.
Several states have explicit three-way reconciliation mandates. In California, Rule 1.15 of the Rules of Professional Conduct and the Client Trust Account Protection Program (CTAPP) require lawyers to register their trust accounts annually with the State Bar, complete a yearly self-assessment, and maintain detailed ledgers for each client; the State Bar's guidance is at calbar.ca.gov. In New York, Judiciary Law Section 497 and Rule 1.15 of the Rules of Professional Conduct require lawyers to maintain contemporaneous records of every trust deposit and disbursement, with each transaction assigned to a specific client. Illinois — under revised Rule 1.15A effective July 1, 2023 — requires lawyers to perform three-way reconciliation no less than quarterly (most firms do it monthly as a best practice), retain trust account records for seven years, and participate in the Lawyers Trust Fund of Illinois IOLTA program.
The consequences of getting this wrong are severe and well-documented. State bar disciplinary opinions routinely publish cases in which lawyers have been suspended or disbarred for commingling, conversion, or simply for failing to maintain the required records — even when no client money was actually lost. The failure to reconcile is itself, in many jurisdictions, an independent violation.
Ethics warning: In most jurisdictions, you do not need to intend to steal client funds to be disciplined. Negligent trust account management — including the failure to perform regular reconciliations — is itself sanctionable conduct. "I didn't know" is not a defense.
A clean monthly 3-way reconciliation takes a well-organized firm between thirty minutes and two hours. It takes a disorganized firm days, and that time cost is usually what leads firms to skip or shortcut the process. The workflow below is what your state bar examiner will expect to see if you are ever audited.
Step 1: Gather the bank statement. Download the IOLTA bank statement the moment it's available — ideally the first business day of the following month. Do not proceed until you have the official statement; a mid-month balance from online banking is not sufficient documentation.
Step 2: Run the combined trust ledger report. In your practice management or accounting software, pull the month-end balance of the trust control account. This is the single top-line number representing all money you hold in trust for all clients combined.
Step 3: Run the individual client trust ledger report. Pull a report that lists every client matter with a trust balance as of month-end, and sum those balances. Every practice management system with proper trust accounting (Clio, CosmoLex, LeanLaw, PCLaw) will produce this report natively.
Step 4: Compare all three numbers. They must match exactly. Any variance, even one dollar, must be investigated and resolved before the reconciliation can be signed off.
Step 5: Investigate and document any variance. Variances typically come from timing differences (a deposit in transit, an outstanding check) or from errors (a deposit misposted to the wrong client). Timing differences are reconciling items — documented, not "fixed." Errors must be corrected with a journal entry and explanatory note.
Here is a comparison of what each of the three ledgers should contain:
| Ledger | Source | What It Shows | Who Maintains It |
|---|---|---|---|
| Bank Statement | Financial institution | Actual cash balance in the IOLTA account as of month-end, including cleared deposits and cleared disbursements | Bank (external, authoritative) |
| Combined Trust Ledger | Firm accounting / practice management software | Running total of all money the firm is holding in trust across every client matter | Firm (internal control account) |
| Individual Client Ledgers (summed) | Firm accounting / practice management software | Balance held for each specific client matter, summed to a total | Firm (per-client subsidiary ledgers) |
If any of the three is missing — if, for example, the firm only tracks a combined balance and does not maintain per-client ledgers — the firm is out of compliance regardless of whether the numbers would match.
In our experience reviewing law firm books during onboarding, the same six issues account for the overwhelming majority of IOLTA reconciliation problems. Each is a preventable error, and each can trigger a disciplinary inquiry.
1. Bank fees charged against the trust account. This is the single most common violation. The bank charges a wire fee, a returned-check fee, or a monthly service charge, and the fee hits the IOLTA account. Attorney money — even a few dollars — cannot remain in the IOLTA account. Most state bars require the firm to replenish the shortfall from operating funds within a very short window (commonly within three business days, though specifics vary by jurisdiction). The underlying banking arrangement should have fees billed to the operating account, not the trust account.
2. Client funds commingled with operating funds. A retainer is deposited directly into the operating account instead of IOLTA, or earned fees are left in trust past the point they were earned. Either direction is a violation. Earned fees must be withdrawn from trust promptly; unearned funds must never sit in operating.
3. Interest assignment errors. Interest earned on an IOLTA account, by design, does not go to the client or to the firm — it goes to the state's IOLTA program (for example, the Lawyers Trust Fund of Illinois or the State Bar of California's IOLTA grants program). If your software or your bank is crediting that interest to the firm or to a client, something is misconfigured.
4. Deposits recorded in the wrong client ledger. A check from Client A's settlement is posted to Client B's matter. The combined trust balance still matches the bank, but Client A is now understated and Client B overstated. This is precisely the error that only a 3-way reconciliation catches.
5. Disbursements against uncleared deposits. A client's retainer check has been deposited but has not yet cleared the bank. The firm writes a trust check for costs against that balance, and the trust check clears before the deposit. The account is briefly in overdraft — and in most jurisdictions, this is a reportable event. Your bank may be required to notify the state bar automatically.
6. Stale checks. Trust checks uncashed for extended periods (commonly 90 to 180 days) create reconciling items that accumulate over time. Each stale check should be investigated, reissued if the payee is reachable, or escheated to the state's unclaimed property fund per applicable abandoned property law.
Ethics warning: A single instance of an IOLTA account going into overdraft — even by a few cents, even for a few hours — is treated by most state bars as a reportable event. Banks participating in IOLTA programs are generally required to notify the state bar when this occurs. The inquiry that follows is not optional.
Trust accounting recordkeeping is not just about the reconciliation itself. State bar examiners and auditors require a specific body of supporting documentation, and the retention period is long. Most states require records to be preserved for five to seven years after the termination of the representation, though specifics vary — California generally requires five years, Illinois generally requires seven, New York generally requires seven, and some jurisdictions require longer. Check your specific state's rule.
At minimum, your firm must preserve the following records for every IOLTA account:
| Record | Purpose | Typical Retention |
|---|---|---|
| Monthly bank statements | Authoritative balance record | 5-7 years per state rule |
| Deposit slips and deposit records | Proof of funds received per client | 5-7 years |
| Cancelled checks (or images) | Proof of disbursements and payee | 5-7 years |
| Client ledger cards (per matter) | Per-client transaction history | 5-7 years after matter close |
| Monthly 3-way reconciliation reports | Proof of compliance process | 5-7 years |
| Reconciliation variance notes | Evidence errors were identified and corrected | 5-7 years |
| Signed client fee agreements | Basis for earned-fee withdrawals | Per applicable rule |
| Trust disbursement authorizations | Documentation that disbursements were proper | 5-7 years |
The reconciliation itself should be a physical or digital document — signed, dated, and stored — not just a report that lives transiently inside your software. Many firms print and sign the monthly reconciliation, scan it, and file it in a dedicated compliance folder. If you are ever audited, the existence of signed monthly reconciliations over a multi-year period is often the single most important piece of evidence that your firm takes trust compliance seriously.
Several practice management and accounting platforms handle IOLTA trust accounting and 3-way reconciliation well. The common denominator is native support for per-client trust ledgers, a dedicated trust control account, and a reconciliation report that produces the three balances side by side.
Clio Manage and CosmoLex are the two most widely adopted cloud practice management systems for small and mid-sized firms. Both maintain separate trust ledgers per matter, enforce no-overdraft safeguards, and produce monthly 3-way reconciliation reports that are auditor-ready. CosmoLex includes full double-entry accounting natively; Clio pairs with QuickBooks Online via integration for the general-ledger side. For most firms under 50 attorneys, either is a strong choice.
QuickBooks Online paired with LeanLaw is a popular combination for firms that want the accounting power of QuickBooks with the trust-accounting discipline LeanLaw layers on top. LeanLaw enforces trust rules — no overdrafts, no commingling, per-matter ledgers — inside the QuickBooks environment. This combination tends to work well for firms that already have a QuickBooks workflow in place and want to extend it rather than migrate.
PCLaw (now part of LEAP) is the legacy desktop product many established firms have used for decades. It remains a capable trust accounting system, but the product is clearly in a mature phase of its lifecycle; firms evaluating new deployments generally start with a cloud option. Regardless of which system you choose, the decisive question is not the brand — it's whether the software produces a genuine, auditable 3-way reconciliation report every month. If it doesn't, it's the wrong tool for a law firm.
Every firm eventually hits a threshold where doing trust accounting in-house becomes more risk than it's worth. Some signals that DIY is getting dangerous:
The math on outsourcing is usually straightforward. A specialist bookkeeping firm that handles law firm trust accounting will perform the monthly 3-way reconciliation, document variances, maintain audit-ready records, and flag issues before they become disciplinary problems. The cost is generally a fraction of what a single hour of state bar defense counsel runs — and orders of magnitude less than the cost of a suspension.
Pro tip: The firms that get into trouble are rarely the ones that tried to cheat. They are almost always the ones that got busy, let a month slip, then another, and then discovered a problem six months later they could not unwind. Consistency is the whole game.
