How to Read a Legal Bill Like a Cost Lawyer: Your Guide to Fair Fees

If you’ve ever opened a legal bill and felt your eyes glaze over, you’re not alone. Legal invoices can be dense, full of jargon, and—sometimes—full of charges that shouldn’t be there.

At Law In Check, we review bills every day to help clients spot when lawyers overcharge their clients. Once you know how to break down a bill into its parts, you’ll quickly see where costs make sense and where they might be inflated.

Here’s how to read a legal bill like a cost lawyer.

1. Start with the Cost Agreement

Before you even look at the bill, find your cost agreement (the contract you signed with your lawyer). This sets out:

• The hourly rates for each team member.
• how time will be recorded (e.g., 6-minute units).
• What disbursements will be charged.



If something on the bill doesn’t match the agreement, it’s your first red flag.

2. Understand Billing Units

Most law firms bill in units—often 6 or 10 minutes per task. That means a 2-minute phone call can be billed as 6 minutes.

Where overcharging hides:
• Multiple short tasks billed separately instead of being grouped together.
• Time “rounded up” repeatedly across the bill.



Tip: Add up the total units charged in a day to see if it’s realistic.

3. Break Down Professional Fees

The “Professional Fees” section covers the lawyer’s time. Look for:

• Clear descriptions - Each entry should say what was done, why, and for how long.
• No duplication – Make sure the same task isn’t billed by two different people without explanation.
• Appropriate staff – Admin work (like filing or photocopying) should be billed at an admin rate, not a senior lawyer’s rate.

4. Scrutinise Disbursements

Disbursements are expenses your lawyer pays on your behalf—such as:

• Court filing fees
• Expert witness fees
• Barrister’s fees
• Travel expenses

Where overcharging hides:
• Charging for internal overheads (e.g., printing, postage) as disbursements.
• Duplicate charges for the same expense.
• Mark-ups on third-party costs without disclosure.



Tip: Ask for copies of receipts or invoices for large disbursements.

5. Check for GST

In Australia, legal services attract 10% GST—but it must be applied correctly:

• GST should be on professional fees and certain disbursements.
• Some disbursements (like government filing fees) are GST-free—check you’re not being charged GST on these.

6. Look for Vague Entries

Entries like “work on file,” “emails,” or “telephone call” without detail don’t help you assess whether the work was necessary. The LPUL requires sufficient detail in bills.

Tip: You have the right to request an itemised bill if your invoice isn’t detailed enough.

What to Do When Your Lawyer Overcharges You

If your review turns up questionable charges:

• Ask for clarification – Sometimes errors are genuine and can be corrected.
• Request an itemised bill – This forces the lawyer to break down every charge.
• Seek independent advice – A cost lawyer can tell you if the charges are fair.
• Act quickly – Under the Legal Profession Uniform Law, there are strict time limits for disputing a bill.



Understanding your legal bill is the first step to protecting yourself from paying more than you should. By reviewing your cost agreement, checking how time is billed, scrutinising disbursements, and looking out for vague or duplicated charges, you put yourself in a stronger position to question anything that doesn’t seem right.

If you’ve found charges that don’t add up—or you simply want peace of mind—our team at Law In Check can review your bill and identify potential savings. Even small discrepancies can add up to big reductions.
