What happens if both parties violate restraining order?

Answer 1

Valid for the US only: The answer will depend on the specifics of the order and the statutes in your state. However, in most states, a restraining order (more accurately called a "protection order") is a court mandated document which can only be altered under the authorization of a judge. Neither the protected party or the restrained party are permitted to interpret or alter or ignore any provision of the order. Therefore, if a no contact order is issued, and the protected party invites the restrained party over for a quick chat "just to sort things out" both parties are in violation and , in some states if it is a DV related order, both parties MUST be arrested for violation of the court order.

Answer 2

You will be held in contempt of court and, depending on the court which issued the order (civil or criminal), you could either be fined (civil) or fined AND jailed (criminal).

Answer 3

Then both are in contempt and both can be appropriately sanctioned.
