Law Firm Accounting: 4 Common Legal Accounting Mistakes

Updated: Jan 25

1. Mismanaging trust accounts

Every law firms have an account to hold money on behalf of a client for their case. This is a common practice in law firms to secure cash flows from their clients. This means that the funds may be owned by the law firm, but they do not belong to the law firm until earned.

It is quite complex since law firms need to keep track of each client’s ledger while keeping all trust amounts pooled in one bank trust account. Law firms need to ensure that one client’s funds are not mingled with one another. Moreover, the client’s funds must not be used to pay the law firm’s fees.

Common pitfalls faced by law firms:

  • Overdraft client ledgers at the transaction level.

  • Post transactions to an inappropriate account, such as an income or expense account.

  • Failure to comply by neglecting the three-way reconciliation process.

2. Proper Accounting of Case Costs

In legal accounting, all cases expenses are not treated the same. It is important to ensure that every item billed is tracked and invoiced. Client costs should also be tracked to ensure advanced funds are reimbursed since entries provide little value if they’re not allocated to a particular matter. Without the association to a legal matter, the client will never actually be billed for the item.

3. Income and Revenue Differentiation

Law firms that do not separate revenue from actual income will have inaccurate books. This creates compliance issues and makes it difficult to identify which cases are of value to them.

Therefore, the incidental cost of a case must be allocated before the invoice is paid. Since this is not income, this part must be recorded separately.

Recording income is not always as simple as recording an entry when a payment is received. Each type of income requires its specific entry into the accounting system.




4. Data Entry Errors While Syncing Legal Billing & Accounting Systems

Some law firms use two different systems for their accounting and billing payments. This means that all financial data must be recorded twice, but must be done accurately on both systems. Failure when synchronizing these two systems will create bookkeeping problems, leading to complicated billing or a violation of ethics, and wrong financial data to be analyzed.

Every law firm is a business and to achieve success, accurate financial data is required to make the right business decisions.
