## Checking plan

**Source-by-source verification**

Trace relied-on content to independent sources and check for relevant material the output has missed.

- What the AI does: From the costs order, the bill or the costs records and any objections, build an item table by stage with the amount claimed, the basis in the records and the likely points of dispute, and calculate scenarios for the estimate.
- What the lawyer does: The lawyer decides the positions to take, whether to negotiate or refer to mediation, and prepares any material the registrar requires.
- Who reviews: Responsible lawyer with competence in the matter
- Basis: Practical workflow informed by the linked primary sources; the traffic light and working checks are editorial guidance, not a court classification.
- Why: The level reflects what the work is, the consequence of an error, and how much of the output the lawyer must independently re-derive.

## Checks the lawyer makes

1. Confirm the material (including produced and subpoenaed documents subject to the implied undertaking or any confidentiality order) may go into the tool before it is used.
2. Check each item against the records and the costs order.
3. Confirm the scale or basis that applies.
4. Confirm the client’s settlement authority before any negotiation.

## Notes

- These are suggested working checks. Confirm the required checking with the responsible lawyer before work starts; the checking approach does not establish permission to use AI.
