Is there normally a deposition hearing for child support?

Not normally. In Pennsylvania, discovery is only permitted with special order of the court. My children's father was successful in getting the courts permission for discovery. I think the lawyer just wants to maximize billable hours. His attorney kept stating it is a complex case and asking for continuances in addition to discovery. So the court ordered us to testify solely by deposition, because the normal child support hearing is de novo, only about 10 minutes is available.
