Can judges be present in the public seat during the trial in the courtroom? Please help!

"the public seat"?

Normally, a trial is open to the public. There is seating available for a number of members of the public. And that would include any judge not assigned to the case.

Where is this (what country) and what kind of a case (criminal or civil) is it? The reason I ask this is that I find the term "public seat" to be bizarre.

Depends on the reason for the debt. Generally no, but there are exceptions to both.

"Retired pay may be garnished for enforcement of a retired servicemember's legal obligations to provide child support or make alimony payments. Upon receipt of a valid court order, the Defense Finance and Accounting Service in Cleveland (DFAS-CL) may use retired pay that may be available, including any allotments from such pay, to satisfy the amount of the writ. The amount of writ can include all retroactive amounts for which a retired servicemember may be delinquent in child support or alimony payments. DFAS-CL will attempt to notify a retired servicemember of any garnishment against retired pay. Only the retiree's disposable retired pay is subject to garnishment."

SSD is the same.
