Appeal a decision about payment amounts
An appeal to an independent tribunal can be made if anything relating to the child support calculation is disputed. Get specialist advice if the client wants to appeal the assessment. Before you can appeal, you must contact the CMS to ask for the decision to be looked at again. This is called mandatory reconsideration.
1 If you are unhappy with the outcome of the mandatory reconsideration, you can appeal to the First-tier Tribunal (Social Security and Child Support) within one month of getting the decision. If you submit your appeal after a month, you must explain why you did not do it earlier.
