This procedure contains instruction for WA ex-nuptial child support cases only.

This document outlines information about Section 107 (s107) and Section 143 (s143) orders for WA ex-nuptial Child Support customers.

About s107 orders

Section 107 of the Child Support (Assessment) Act 1989 provides that a person can apply to a court for a declaration that the person should not be assessed in respect of the costs of the child because the person is not a parent of the child. The reason for a person to make a s107 application is where the person disputes paternity of the child concerned.

An application for a declaration under s107 should not be made if a court has already declared under section 106A that the payer should be assessed in respect of the costs of the child. The payer has the option to lodge an appeal against the section 106A declaration. However, if the court does make a declaration under s107 in these circumstances Child Support will give effect to the order.

Requirement to serve

A person applying for a s107 declaration is obliged to serve a copy of their application upon Child Support, as well as serving a copy upon the respondent i.e. the payee. If a person applies for a declaration Child Support must suspend payments to the payee for that child until the court makes a decision. See the Child Support Guide 4.3.2: Applications and orders about decisions under the Assessment Act.

About s143 orders

From 1 January 2007 where a court has made a declaration under s107 and child support has been paid to the payee for that child, the court must immediately consider making a s143 order (a Parentage Overpayment Order). A s143 order allows the person to recover some or all of the child support paid to the payee. See the Child Support Guide 3.1.2: Parentage overpayment orders.

Where a s143 order is made, it will be registrable as a maintenance liability and can be collected by Child Support. These monies can be collected in the same way as most child support liabilities including tax refund intercepts.
