Client ledgers are individual records that track each client’s money within your firm’s trust account. Even though all funds sit in one IOLTA bank account, you need a separate ledger for each client or matter showing their deposits, disbursements, and current balance. The total of all client ledger balances should always equal your trust account balance.

Start by creating a ledger for each client matter that will hold funds. Some firms track at the client level, others at the matter level if a client has multiple cases. Each ledger needs to capture the client or matter name, date of each transaction, description, deposit amount, disbursement amount, and running balance.

Every time money comes into the trust account, record it on the specific client’s ledger. Retainer received from Smith goes to Smith’s ledger. Settlement funds for Garcia go to Garcia’s ledger. When you disburse from trust to pay costs, transfer earned fees to operating, or refund unused retainer, that comes off the appropriate client’s ledger.

The critical rule is that no client ledger can ever show a negative balance. You cannot use one client’s money to cover another client’s expenses. If Garcia’s ledger shows $500 and you need to pay $600 in costs for their case, you need to collect more funds first. A negative balance means you’ve either made a recording error or actually misused trust funds.

Most law firms use practice management software like Clio, PracticePanther, or MyCase to manage client ledgers. These systems are designed for legal billing and generate client ledgers automatically as you record trust transactions. Clio integrates with QuickBooks, letting you maintain detailed client ledgers in your practice management system while keeping clean accounting records separately. A LA County bookkeeper for small business with legal industry experience can help configure this integration properly.

If you’re tracking ledgers in QuickBooks without legal-specific software, set up each client as a sub-account under your trust liability account. This works but requires more manual discipline to ensure every deposit and disbursement gets coded correctly.

Monthly three-way reconciliation ties everything together. You match the bank statement balance, your book balance in the trust account register, and the total of all client ledger balances. All three numbers must agree. If they don’t, you have an error to find before closing the month.

California State Bar rules require law firms to maintain trust account records including individual client ledgers for at least five years. During a random or triggered audit, the Bar will review your ledgers alongside bank statements and reconciliation reports. Proper law firm trust accounting setup from the start makes these audits straightforward rather than stressful.
