i would complain to his department and ask why

You need a grounds to set aside a plea and courts hate this, so this will be uphill struggle since they read you the riot act and it is recorded...

You need to file DWc-1 claim form and get an attorney.. Only if the work comp carrier determines not work related, this can be litigated

need to clear it up because even with no valid service and such, the court never knows this unti it is brought up.

you could call the police but many times, they will not get involved in family disturbance.

they police, do you mean the police? Where they involved.. Did the police check your id and take a statement?

attorney can make special appearance for just his hearing but he has to file a limited scope.. you may have to testify if evidence is hearsey.

Most PDs will not talk to any one but the defendant, not his family. You can ask to address the court but. letter is improper ex parte

No warning is required . You could fight it.

Yes it is against the law . You may or may not get in trouble but don't do it again
