Bar association model rules require that billing be accurate, transparent, and not deceptive. Automated time tracking software introduces new questions: can a timer running in the background generate a billable entry? Who is responsible when an AI suggests a time entry? What is the lawyer's duty to review before billing?
Key Analysis
Model Rules of Professional Conduct Rule 1.5 requires fees to be reasonable — which includes accurate timekeeping.
Bar association ethics opinions are increasingly addressing AI-assisted billing: the consensus is that the supervising lawyer must review every AI-generated billing suggestion before it is applied.
Double-billing detection is not just a software feature — it is a professional conduct requirement. Billing the same time unit to two clients is grounds for disciplinary action.
Risk Signals
AI-suggested billing entries applied to invoices without lawyer review.
Time tracking software that rounds up time aggressively without disclosure to the client.
No audit trail linking billing entries to the original work log — making double-billing undetectable.
Action Items
Require explicit lawyer review and approval of every billing entry before it is applied to an invoice.
Disclose rounding policies in the fee agreement and ensure the software implements exactly what was disclosed.
Implement double-billing detection that alerts on any time overlap before the billing entry is saved.
