A client owes the firm money, while the firm is still holding funds for that client. Commercially, it may seem sensible to retain those funds until the outstanding invoice is settled.
However, a solicitor cannot automatically retain client money for an unpaid invoice simply because the client owes the firm money. The key question is why the funds are being held.
That distinction matters where money was received for a specific purpose, such as counsel’s fees, tax, a transaction or another third-party payment.
Start with the purpose of the client money
Before deciding whether money can be retained or transferred, the firm should identify exactly why it received the funds.
Money paid on account of future legal fees may be capable of being applied to properly billed costs, subject to the engagement terms, the client’s instructions and the relevant SRA requirements.
By contrast, money held for a specific external payment or defined purpose should not automatically be redirected towards the firm’s invoice.
The original article correctly centres this issue on purpose. A client-account balance should not be treated as one general pool simply because the same client also owes money to the firm.
Can client money be used to pay an outstanding invoice?
Potentially, but only where the money is properly available for that purpose.
Where client money will be used to pay the firm’s costs, the firm must first provide the client or paying party with a bill of costs or other written notification of the costs incurred. The amount transferred must also relate to the specific sum identified.
That means an unpaid invoice does not create a general right to treat every client-account balance as available for the firm’s fees.
A balance may exist on the ledger, but the firm still needs to understand why that money is being held and whether it can properly be applied to the outstanding costs.
When should a solicitor not retain client money for an unpaid invoice?
A firm should be particularly cautious where the money has no direct connection to the outstanding bill.
For example, funds held for tax, counsel’s fees, a transaction or another defined payment should not automatically become security for an unpaid office-account debt.
The same principle applies where a matter has finished and there is no longer a proper reason to retain the remaining balance. In that situation, the firm should not delay repayment simply because an invoice elsewhere remains unpaid.
Where the position is unclear, the firm should review the client ledger, engagement terms, written instructions and billing history before taking further action.
What should the firm review before retaining or transferring client money?
We recommend a documented decision process rather than relying on assumptions.
The first step is to confirm the source and purpose of the funds. The firm should then establish whether that purpose still applies and whether the client has received a bill or written notification of the relevant costs.
It should also consider whether the money can properly be applied to those costs and whether any client instructions affect the position.
If there is uncertainty, the issue should be escalated to the responsible solicitor or COFA before money is retained or transferred. The decision should then be recorded clearly so there is a reliable audit trail.
Residual client balances need prompt attention
Residual balances can become a problem where a matter has finished but the client account has not been reviewed properly.
A good matter-closing process should include a review of the final client ledger, any remaining third-party payments, the billing position and any balance due back to the client.
If there is no longer a proper reason to hold the money, the firm should deal with the balance promptly.
This is not simply an administrative issue. Unresolved client balances can create unnecessary work and weaken the firm’s overall control environment.
The operational problem behind the legal question
Small firms often encounter this issue because client-account management and credit control sit with different people.
The cashier sees money on the ledger. The fee earner sees an unpaid bill. The client may expect a refund. Meanwhile, nobody has a complete view of why the funds are being held and what should happen next.
We recommend linking these processes rather than treating them separately.
A good system should identify matters where a client balance and overdue office debt exist at the same time. However, it should not assume that one can automatically be used to settle the other.
That decision still needs to be based on the purpose of the funds, the billing position and the relevant authority.
Better credit control without relying on client money
Returning money that should be returned does not mean accepting poor payment behaviour.
Strong credit control starts much earlier. Appropriate payments on account, prompt billing, clear payment terms and regular follow-up all reduce the risk of overdue invoices.
Firms should also resolve billing queries quickly and make timely decisions about whether further work should continue where payment remains outstanding.
Client account should not become a substitute for a structured credit-control process.

Frequently Asked Questions
1. Can a solicitor retain client money because an invoice is unpaid?
Not automatically. The firm must consider why the money is being held and whether there is a proper basis for retaining or transferring it. An unpaid invoice alone does not make unrelated client money available to the firm.
2. Can money paid on account be used to pay legal fees?
It may be, provided the money is properly available for that purpose and the relevant requirements are met. The firm should also ensure the client has received the necessary bill or written notification before any transfer takes place.
3. Does client money have to be returned when a matter ends?
If there is no longer a proper reason to hold the money, the remaining balance should be dealt with promptly. The firm should therefore review the client ledger carefully when closing the matter.
4. Can money held for a disbursement be kept against an unpaid invoice?
Not simply because the invoice is outstanding. The firm should consider the original purpose of the money and whether it can properly be applied to the firm’s costs.
5. What should a firm do if it is unclear whether client money can be retained?
The position should be reviewed before any transfer or continued retention. We recommend checking the ledger, engagement terms, client instructions and billing position, then escalating any uncertainty to the responsible solicitor or COFA.
