Privilege and Billing Safeguards
- Protect privilege: never include legal advice, mental impressions, or litigation strategy.
- Be specific: avoid vague phrases like "legal research" — always name the topic.
- Tie work to objectives: connect entries to matter goals or compliance requirements.
- Show policy compliance: rates, caps, task codes, approved expenses.
- Flag anomalies: unusual expenses, staffing changes, large time spikes.
- No duplicate billing: do not overlap timekeeper entries for the same task without explanation.
- No administrative padding: exclude admin tasks unless guidelines permit.
- Stay consistent: narrative must match time entry descriptions and invoice totals.
