the other parent with a written explanation of its decision and any other relevant
papers from the Child Support Agency file.
Once these documents have been received, the SSAT notifies the applicant and the
other parent of an appointment time for a SSAT Hearing, or in some circumstances, a pre-hearing conference.
An SSAT Appeal usually takes 10-12 weeks from the date of lodgement.
Once the review has been determined the SSAT will provide the decision and the
reasons for the decision.
