Understanding Legal Costs & Billing

Common charging models include:

• Hourly rates — charging for time spent, often at different levels.
• Fixed fees — a set price for clearly defined work.
• Capped / agreed fees — a maximum or pre-agreed figure.
• Conditional (“no win, no fee”) — arrangements with risk and uplift components.

You should feel clear about:

• what you will be charged for;
• what is included and what counts as an extra;
• how you will be told about changes or overruns.

“It depends” can be true — but you should still expect meaningful cost information.

You are normally entitled to:

• a written cost estimate at the start;
• a simple explanation of factors that may increase or reduce cost;
• reasonable notice if the estimate may be exceeded.

Common warning signs:

• nothing in writing;
• new estimates without explanation;
• unexpected or surprise bills.

Track changes using the Cost Monitoring Sheet.

A clear bill usually shows:

• what work was done,
• who did it and when,
• how charges were calculated,
• any disbursements (payments to third parties).

Patterns that often cause confusion:

• vague entries such as “work on file”,
• administrative extras you were not told about,
• charges relating to correcting the firm’s own mistakes.

You can ask the firm to clarify any entries. Keep all correspondence as part of your evidence record.

• Get a written estimate early.
• Ask to be warned about overruns.
• Use the Cost Monitoring Sheet to track changes.
• Query unexpected items calmly and in writing.
• Keep written records of all cost discussions.

Unexplained cost increases may form part of a service complaint.

ChatGPT can help you:

• translate billing language into plain English,
• spot vague entries,
• draft calm follow-up questions.

Example prompt:

“Here is a redacted legal bill. Please identify any unclear entries and suggest neutral clarifying questions. Do not add new facts.”

Always check summaries against your original bill. You stay responsible for what you decide and send.
