## Checking plan

**Lawyer review required**

The responsible lawyer reviews the work against the instructions, sources and intended use.

- What the AI does: Potential support includes extracting and organising information and preparing preliminary structure or wording. Confirm the tool’s capability and permitted scope.
- What the lawyer does: Set the scope, verify the evidence, resolve exceptions and approve the final output for its intended use.
- Who reviews: Responsible lawyer with competence in the matter
- Basis: Suggested checking approach based on the task guidance. Complete the assessment for the actual tool, information and jurisdiction.
- Why: The plan reflects the described work and review requirements. Policy colours are not used to determine permission or checking.

## Checks the lawyer makes

1. Confirm that the wording reflects the client’s instructions and contains no unintended admission, concession or commitment. Check the recipient and tone.
2. Confirm that the actual tool, feature and processing terms permit use of this information, including access, retention, training and disclosure conditions.
3. Review the original source set for relevant material absent from the output, including contrary evidence, qualifications and unresolved gaps.
4. Confirm the output against the client’s instructions and the complete relevant source material, including omissions or contradictions.
5. Resolve exceptions and record the responsible lawyer’s approval of the exact output and intended use.

## Notes

- Confirm the required checking with the responsible lawyer before work starts. The checking approach does not establish permission to use AI.
