How to fight a protective order in indiana
Read the order.
The county sheriff will probably serve you with a copy of the protective order. Protective orders can be issued " ex parte, " which means that the judge issues it without hearing from you.
The order should lay out what you are prohibited from doing: contacting the petitioner, possessing a firearm, etc. You may also be served a summons or a notice of hearing along with the order.
