What is a Child Support Agreement

How do you do a written Child Support Agreement yourselves 

Doing a Child Support Agreement without the Child Support Agency

The Child Support (Assessment) Act 1989 provides flexibility for parents who want to make their own Child Support Arrangements and document those arrangements in a Child Support Agreement.

Child Support Agreements include provisions for periodic, non periodic or lump sum payments from one parent to the other.

The Child Support Agreement might also make provision about payments by one or both parents to third parties.

Those third parties might include schools, banks, insurance companies, medical practitioners and the like.

Child Support Agreements may be registered or unregistered.




The two types of registered Child Support Agreements which can be entered into by parents are:

  • Binding Child Support Agreements;
  • Limited Child Support Agreements.


Both Binding and Limited Child Support Agreements can be registered with the Child Support Agency, the Australian Tax Office and Centrelink.

Parents might agree to enter into one Child Support Agreement which deals with two or more children, however consideration should be given to specifying a separate rate for each Child.
