Trust accounting is one of the most regulated areas of bookkeeping in Australia. Every state and territory law society sets its own rules for how solicitors must handle client money, and the consequences of non-compliance — whether intentional or inadvertent — are severe. Bookkeepers taking on a legal practice client need to understand the framework before they touch a single transaction.
Why Trust Accounts Exist and What Makes Them Different
When a client pays money to a solicitor in anticipation of legal services — a settlement advance, a conveyancing deposit, a damages award — that money belongs to the client, not the firm. It must be held in a separate trust account, completely quarantined from the firm's own operating funds. The legal practice acts in each state make this mandatory and create criminal liability for misappropriation.
This is categorically different from a business holding a customer deposit. The trust account is not the firm's asset. It cannot be used to pay the firm's rent, even temporarily. It cannot be overdrawn for any reason. Every dollar in the trust account must be traceable to a specific client matter.
Three-Way Reconciliation: The Core Control
The central control in legal trust accounting is the three-way reconciliation, performed at least monthly (some jurisdictions require it monthly without exception). It reconciles three separate records:
- Trust bank statement balance — the balance shown on the bank's records at the reconciliation date.
- Trust cash book balance — the balance in the practice's own records of trust receipts and payments.
- Ledger balance — the sum of all individual client trust ledger balances at the same date.
All three figures must agree. If they do not, something is wrong — possibly a data entry error, possibly something more serious. The reconciliation must be signed off by the principal solicitor and the records must be retained.
In practice, I recommend running the three-way reconciliation weekly rather than monthly. It takes minutes with modern software and makes month-end a non-event. Waiting until month-end means a discrepancy discovered on the 30th could represent four weeks of cumulative errors.
State-by-State Differences
While the broad framework is consistent, the details differ by jurisdiction:
- NSW: The Legal Profession Uniform Law (LPUL) applies. External examinations are required annually, conducted by an approved external examiner appointed by the Law Society.
- Victoria: Also under LPUL. Similar external examination requirements. The Law Institute of Victoria publishes detailed trust accounting guidelines.
- Queensland: The Legal Profession Act 2007 applies. The Queensland Law Society has its own inspector program and requires monthly reconciliations to be filed.
- WA, SA, TAS, NT, ACT: Each has its own legislation. Some require the external examiner to be a registered auditor; others accept a qualified accountant.
Bookkeepers should download the current trust accounting handbook from the relevant law society before engaging with a legal practice client. These handbooks are detailed and practical, and staying current with them is non-negotiable.
Common Violations and How to Prevent Them
The law society inspectors see the same failures repeatedly:
Mixing trust and office funds. This is the most serious violation and can be inadvertent. A common scenario: a cheque arrives from an opponent and is banked into the office account by mistake. Establish a physical workflow — separate bank deposit books, separate incoming mail trays — to prevent this.
Overdrawn client ledgers. No individual client's ledger balance can go negative. Drawing more from trust than a client has on ledger is a technical deficiency even if the overall trust account has a surplus. Use software that prevents this at the transaction entry stage.
Late transfers to office account. Once costs are billable (a tax invoice has been issued and the time to raise a dispute has passed, typically five days), the funds must be transferred to the office account promptly. Leaving billed funds sitting in trust indefinitely is a common finding.
Incomplete matter ledgers. Every client matter that ever receives trust money must have its own ledger, even if the amount is small and the matter is long closed. Destroying or losing ledger records is a violation regardless of how old the matter is. Most jurisdictions require trust records to be retained for seven years.
Interest on trust accounts. Trust accounts must be held at an authorised deposit-taking institution in an account that generates interest. The interest does not belong to the client or the firm — it must be remitted to the Public Purpose Fund (the specific fund name varies by state). Failing to set this up correctly at account opening is a compliance issue from day one.
Software and Integration Considerations
Most legal practice management software (LEAP, Smokeball, ActionStep, Law Master) has built-in trust accounting modules that enforce the three-way reconciliation and prevent overdrawn ledgers. If a firm is using general-purpose accounting software without legal trust modules — which still happens in small suburban practices — the risk of errors is materially higher.
As a bookkeeper, you should not be maintaining trust records in Excel or a manual ledger in 2026. If a client insists on this, document your concerns in writing.
When integrating legal practice management software with a general ledger (for example, to produce the firm's P&L), be clear about what should and should not flow across. Trust receipts and trust payments are not income and expense — they are movements in a liability (trust money held). Only the fee transfers from trust to office represent income recognition.
Practical Advice for Bookkeepers New to Legal Clients
If you have not previously worked with a legal practice, the best starting point is to complete the trust accounting CPD module offered by your professional association (ICB or AAT) and to read the relevant law society's handbook cover to cover. Then, before you process a single transaction, ask the supervising solicitor to walk you through their current reconciliation — seeing the three-way reconciliation in action is worth more than any written explanation.
Legal trust accounting is exacting. But with the right processes and software, it becomes one of the more satisfying areas of bookkeeping — because the controls are so clear that a clean set of books genuinely means something.
