My boyfriend has been beating me, how do I charge him with domestic violence and get a restraining order?

This matter sounds like its becoming fairly serious and it can only escalate further if you do not seek help. First of all, you should definitely secure yourself another place to stay. At the same time, you need to go to your local superior court and file a Domestic Violence Claim against your boyfriend which would then issue a temporary restraining order. The restrainig order would prevent your boyfriend from having contact with you, your relatives, and/or children if you guys have any. He would not be allowed to come in within a certain distance from you. He would also be required to pay any medical fees for your injuries or any other damages that were occured.

You can also hire an attorney to make sure he is prosecuted to the full extent with a proper restraining order, and to be sure you are awared fair compensation for your damages. He may very well also hire a Criminal Defense Attorney to fight the charge as well, so it'd be a good idea to speak to a Lawyer immediately. Good luck on everything.
