## 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: Prepare provisional schedules from verified inputs for independent checking.
- 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 current income, care arrangements and relevant family circumstances.
2. Verify the applicable assessment or maintenance process and current calculation inputs.
3. Recalculate figures independently and distinguish an estimate from a formal assessment.
4. Review needs and resources against the supporting financial documents.
5. Record assumptions, unresolved information and the lawyer’s advice.

## Notes

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