Withdraw application

If we haven’t accepted or refused your application yet, you can withdraw it.

Fill in the Notice of withdrawal of application for a child support assessment form.

Wait for the result

We’ll write to you and the other parent to tell you our decision.

If we make an assessment, we’ll send your child support assessment notice. This says:

  • how much you’ll receive or pay
  • when your payments will start.

Check your details

Check that all your details on the assessment notice are right. You need to tell if they aren’t or if they change later.

If you think our decision was wrong

If you don’t agree with a decision we’ve made you may be able to object. Both parents have the right to object.

Read about objecting to Child Support decisions, including what you can and can’t object to.

If we need to contact you

Once you have an assessment, we may need to contact you from time to time about your child support. You can request how and when we contact you through your Child Support online account. To update your preferences, call us on the Child support general enquiries line.

Sometimes we may need to contact you using a different method or outside your preferred contact times. This may happen if:

  • we haven't been able to reach you through your preferred method
  • you don’t make payments on time
  • we need to resolve a specific matter.
