California Courts: Self-Help Center: Protection from Abuse: Domestic Violence: Restraining Orders
FakeBoobsRule Reviewed by FakeBoobsRule on . How do you get a restraining order? In California, against another adult (not a spouse). Would I go to the court house? Local police station? What? And how could I get an immediate restraining order? Thanks in Advance. Peace. (Sorry if this is in the wrong place.) Rating: 5
