After the estimate
What your estimate can help clarify
Use the estimate as a working figure. The useful next step is to separate what is settled, what depends on records, and what may need legal advice.
Care arrangements and records
Note the care pattern that actually happens, where it differs from the estimate, and what records may help explain the difference.
Agreements or proposed terms
If a limited or binding child support agreement is being discussed, review the proposed terms before treating the estimate as a position.
Special circumstances or extra costs
List costs, needs, or circumstances that sit outside the ordinary estimate and may need advice before any application or response.
What to bring to advice
Keep the estimate with the questions it raises
Bring the result, the inputs used, and any notes about assumptions or disputed facts. The estimate is not legal advice and it is not a Formal Assessment.
- Save the result summary before changing inputs
- Write down assumptions and disputed facts
- Gather income, care, cost, and agreement records
