Child Maintenance Payments: What to Do If the Amount Looks Wrong

If a child maintenance amount looks higher or lower than expected, start by checking the information behind the calculation. An unexpected result does not always mean the calculation is incorrect, but it is worth reviewing the details.

Common areas to review

Check gross income, pension contributions, other children in the household, shared-care nights and whether payments have been recorded correctly. Changes in work or care arrangements can also affect the amount.

Get organised before raising a concern

Prepare a short timeline, supporting documents and specific questions. Clear evidence makes it easier to explain what has changed or which figure you believe needs checking. This information is general guidance, not legal advice.
