To have child support based on a formula assessment you need to apply to us.
If you believe using your real name will cause safety concerns for you, a carer, or your child, we may be able to leave your name out when communicating with the other parent. Attach any relevant documents to this form. For example a court order, police report, a letter from a social worker or Work and Income, or a letter from your doctor.
