Restraining orders, whether temporary or final, are civil in nature and do not carry the same kind of penalties involved in criminal cases like jail time. However, the consequences of having a restraining order against you can be potentially far worse than jail.
If a Final Restraining Order is Ordered against you, you will be fingerprinted and placed on a domestic violence registry, and you will be permanently prevented from having any contact with the alleged victims.
Among other things, the Judge can also order that you be prevented from returning home, pay child support, pay spousal support, alter or suspended child custody, prevent you from ever legally possessing a firearm, and fine you.
