Use this form if you want to stop getting child support under a formula assessment, voluntary agreement or court order. Only the receiving carer may cancel a voluntary agreement or court order. 

If cancelling a formula assessment, all receiving carers and any parent who has at least 28% of ongoing daily care must agree to cancel it.

We'll cancel your child support from the date you give us on the form.


My responsibilities

If you're getting the sole parent rate of benefit or Unsupported Child's Benefit, you cannot cancel a formula assessment for child support.

Once you've cancelled child support payments, you cannot later ask us to collect them. If you were owed payments before cancelling, you can collect those by applying through the Family Court.
