It depends what kind of restraining order it is. If you are served a restraining order, it’s typically a TRO (Temporary Restraining Order) or an EPO (Emergency Protective Order). Civilians request TROs, but only law enforcement request EPOs. For more information on these restraining orders visit this page. These types of restraining order last between 7 and 25 days. Whether the restraining order becomes permanent is decided at the restraining order hearing. If the restraining order becomes permanent, it can last as long as 5 years.
