How Should a Law Firm Handle Retainers and Advance Fees?
Aug 12, 2026Retainers and advance fees are a normal part of running a law firm. They help protect the firm from unpaid bills and give clients a clear starting point for the representation. But from a bookkeeping standpoint, they are also one of the most common sources of trust accounting problems.
The core question is simple: has the money been earned yet? The answer determines which account the money belongs in, when it can be moved, and how it must be recorded.
What Is the Difference Between a Retainer and an Advance Fee?
The word “retainer” is used loosely in everyday practice, which can cause confusion. From an accounting perspective, it helps to separate a few different types of payments.
Advance fee deposits
This is money a client pays up front that the firm will bill against as work is performed. Until the firm actually earns the fees, the money belongs to the client and should be held in trust.
Advance cost deposits
These are funds paid to cover expected costs, such as filing fees, court reporter fees, expert fees, or records requests. They also belong to the client until they are spent on the client’s behalf.
Earned fees
These are payments for work that has already been completed and billed. Earned fees belong to the firm and should go into the operating account.
Flat fees and fees described as nonrefundable
Some firms charge flat fees or describe certain fees as nonrefundable or earned on receipt. Whether a particular fee can be treated as earned when received is an ethics question that depends on the fee agreement and the applicable rules. Florida attorneys should review the Rules Regulating The Florida Bar and consult ethics counsel when structuring these arrangements. The bookkeeping should then follow whatever the fee agreement and the rules permit.
Where Should a Retainer Be Deposited?
Advance fees and advance costs should be deposited into the firm’s trust account. In Florida, nominal or short-term client funds generally go into an IOTA account.
Earned fees should be deposited into the operating account. Depositing earned fees into trust and leaving them there can be considered commingling, and depositing unearned client money into operating can be considered misuse of client funds. Neither is a minor error.
When a single payment includes both earned and unearned amounts, firms should follow their jurisdiction’s rules on how to handle it. A common approach is to deposit the full payment into trust and then promptly transfer the earned portion to operating with documentation.
When Can Money Move From Trust to Operating?
Funds can be transferred from trust to operating once the fees have actually been earned. A reliable process usually looks like this:
- The attorney performs the work and records the time.
- The firm issues an invoice to the client showing the work performed and the amount being applied from the retainer.
- The bookkeeper records the earned-fee transfer on the client’s trust ledger.
- The money is transferred from trust to operating, with the transfer tied to the specific client and invoice.
Every transfer should be traceable to a specific client, a specific invoice, and a specific amount. Lump-sum transfers that combine several clients without a clear breakdown make reconciliation much harder and can raise concerns during an audit.
Can a Firm Transfer Fees Too Early?
Yes, and it is one of the most common trust accounting mistakes. Transferring a retainer to operating before the work is done, or moving a rounded amount “to be safe,” means the firm is holding client money in its own account.
The opposite problem also happens. Some firms leave earned fees sitting in trust for months because transfers are not done consistently. Over time this creates firm money in the trust account, which can be considered commingling.
The best protection is a regular billing and transfer schedule, such as monthly, so earned fees move out of trust promptly and unearned funds stay put.
What Happens to an Unused Retainer?
When a matter ends, any portion of the retainer that has not been earned or spent on costs belongs to the client and should be returned promptly. The final invoice should show the total retainer received, all fees and costs applied, and the remaining balance being refunded.
Unused balances that are left sitting in trust after a matter closes are a frequent problem. They can lead to unclaimed funds that become much harder to resolve later.
What Records Should a Firm Keep for Retainers?
For each client who pays a retainer, the firm should be able to show:
- The signed fee agreement
- The date and amount of each deposit
- Which account received the deposit
- Every invoice applied against the retainer
- Every transfer from trust to operating
- Every cost paid on the client’s behalf
- The running balance on the client’s trust ledger
- The final refund, if any
These records should agree with the monthly three-way reconciliation. If a client’s ledger shows a different balance than the firm’s billing system, the difference should be investigated right away.
Tips for Handling Retainers Cleanly
- Use a fee agreement that clearly explains how the retainer will be held and applied.
- Deposit advance fees into trust, not operating.
- Bill against retainers on a consistent schedule.
- Transfer earned fees promptly, one client at a time.
- Never transfer more than the amount invoiced.
- Watch for negative client balances.
- Refund unused balances promptly when a matter closes.
