Child support assessment for same-sex parents

You and the other person on your child support assessment application must be the child's parent or non-parent carer.

Read about who can apply for an assessment.


You’re a parent if you have adopted the child.

Artificial conception

Parents must have been married or in a de facto relationship at the time of the artificial conception procedure and both agreed to the procedure.

Case study

Nicole and Samantha are in a de facto relationship. They decide to have a child together and agree Nicole will be the birth mother. Nicole undertakes an artificial conception procedure. She gives birth to their daughter Louisa.

They break up. Nicole has full time care of Louisa. She applies for a child support assessment.

We decide Samantha has to pay child support as the other legal parent.


You’re both the child’s parents if an Australian court order says you are.

If an assessment names you as your child’s non parent carer

You can ask us to change your assessment to show that you are a parent of your child. This may change the amount of child support you pay or receive.
