Commingling Client Funds: The Trust Accounting Error That Ends Legal Careers

Commingling client funds is the trust accounting violation California attorneys are disciplined for most often, and it almost never begins the way people assume. The attorneys who lose their licenses over it are usually not stealing. They are behind on their bookkeeping.

Rule 1.15 of the California Rules of Professional Conduct requires that funds belonging to clients — settlement proceeds, advanced fees not yet earned, money for court costs — be deposited in clearly identifiable trust accounts and kept separate from the firm's money. The rule is simple. The failure is almost always operational.

This article explains how commingling happens in practice, why the State Bar treats it so seriously, and the monthly discipline that prevents it.

How Commingling Happens Without Intent

The most common route is a negative client ledger. A disbursement goes out on behalf of Client A before Client A's funds have fully cleared, or for slightly more than Client A has in trust. The IOLTA still has money in it — supplied by Clients B through M — so the bank balance looks fine and nothing bounces. Client A's ledger, however, is now negative, which means other clients' funds paid Client A's expense. That is commingling, and it happened without anyone deciding to do it.

The second route is earned fees left in trust. A fee becomes earned under the fee agreement and should move to operating. It does not move. Now firm money is sitting in the client trust account, mixed with client money. The violation exists even though no client lost anything.

The third is the reverse: a firm expense paid from the trust account, often with the honest intention of reimbursing it within the week. There is no compliant version of that transaction.

The fourth is credit card processing fees deducted from a trust deposit. The client's retainer arrives net of the fee, meaning the client's trust balance is short by the amount the processor took. Processing fees cannot be deducted from client funds.

None of these require dishonesty. All of them are findings.

Why the State Bar Treats It as Serious

The Client Trust Account Protection Program exists because of what happens when commingling goes undetected. Investigations following the disbarment of Thomas Girardi revealed that systemic gaps in trust account oversight allowed millions in client funds to be misappropriated over years without detection.

The California Supreme Court responded by approving Rule of Court 9.8.5, and the State Bar adopted the current form of Rule 1.15. California attorneys collectively safeguard over fourteen billion dollars in client trust funds. The regulatory position is that the safeguarding duty is absolute and the records must demonstrate it.

This is why the discipline outcomes look disproportionate to attorneys who committed an accounting error rather than a theft. From the State Bar's perspective, an attorney who cannot demonstrate that client funds were kept separate cannot demonstrate that client funds were safe. Penalties range from formal censure to suspension or permanent disbarment, and even unintentional errors can trigger disciplinary proceedings.

The distinction between careless and dishonest matters at sentencing. It does not prevent the proceeding.

The Controls That Prevent It

Preventing commingling is a monthly discipline built from four controls.

The first is individual client ledgers. Without them, a negative client balance is invisible. The State Bar expects attorneys to track each client's money separately from others in the IOLTA, and a pooled balance cannot do that.

The second is monthly three-way reconciliation. Matching the bank statement, the trust journal, and the sum of client ledgers is the only routine that surfaces a negative ledger before it compounds. A one-way bank reconciliation will balance happily while the problem grows.

The third is a disbursement rule: never disburse more than that client has in trust, and never disburse against funds that have not cleared. Written into firm procedure and enforced at the point of payment, this single rule eliminates the most common cause.

The fourth is prompt movement of earned fees. Transfer them when they are earned, record the transfer against the client ledger, and keep the trust account holding only client money.

Add a quarterly self-audit — sample a handful of matters and trace every transaction end to end — and the exposure largely disappears.

If You Suspect a Problem Already Exists

Discovering a negative client ledger or an unexplained shortfall is uncomfortable, and the instinct to wait and quietly correct it is the wrong one.

Stop disbursing from the account until the position is understood. Reconstruct the client ledgers from bank statements and disbursement records so you know exactly which clients are affected and by how much. Fund any shortfall from the operating account immediately — the firm's money can go into trust to cure a deficiency; client money can never go the other way.

Document what happened, when it was discovered, and what was done. A contemporaneous written record of an error found and corrected reads very differently to a reviewer than a gap that was never mentioned.

Then fix the process that allowed it. A shortfall corrected once and left structurally possible will happen again, and the second occurrence is much harder to characterize as an accident.

The State Bar publishes its trust accounting handbook and requirements at calbar.ca.gov. For a firm that has fallen behind, a bookkeeping cleanup that rebuilds the ledgers and restores monthly reconciliation is usually the fastest route back to defensible records.
