Administrative Appeals Tribunal (AAT) applications against Child Support objection decisions 277-09180010



This document outlines the process involved when a customer lodges a request for the Administrative Appeals Tribunal (AAT) to review a Child Support objection decision.

Lodging an application for an AAT review

A customer may apply to the AAT for an AAT first review of:

  • a decision to disallow, allow or part-allow an objection, or
  • a decision to refuse an application for an extension of time to lodge an objection (EOT refusal)

The AAT refer to this process as an application for review.

A customer may lodge an application for an AAT first review over the phone, in writing or in person with the AAT.

If a customer calls to lodge an application encourage them to contact the AAT.

Note: a customer may withdraw their application for review before the AAT makes a decision. If the applicant withdraws the appeal and the respondent wishes to proceed, the AAT appeal will proceed. For more information See Administrative Appeals Tribunal (AAT) review dismissed or withdrawn.

Lodging an application for an extension of time for review (AAT EOT application)

The AAT has time limits which require a customer to make an application for an AAT first review within a specified time after they receive notification of the objection decision.

If the customer wants to make an application for an AAT first review outside of the prescribed time limits, they may apply to the AAT for an extension of time in which to make an application for review.

The AAT refer to this process as an application for extension of time for review. In these AAT Operational Blueprint documents that process may also be referred to as an AAT EOT application,

A customer must lodge an application for an extension of time for review in writing with the AAT.

If a customer calls to lodge an application for an AAT first review, encourage them to contact the AAT. The AAT will determine whether they are making the application for an AAT first review within the prescribed time limits, or whether they need to make an application for an extension of time for review.
