Nah, I gotta disagree a little tiny bit with RKBAR15 on that one part. The OOP only applies to the defendant or respondent, not to another member of the family (that I can think of anyway).
If wife files criminal charges v. husband or files family offense petition against husband she will receive an order of protection against hubby and he has to turn in firearms. She does not. She only has to turn in firearms if there is an order of protection against her. That can only happen if she is either charged with one of list of crimes (Assault aggravated harassment stalking etc etc) or hubby files family offense petition against her too (so I guess that might be the case where there are mutual orders, in my experience Orders of protection are usually the result of criminal charges.
But if he's a jerk he'll run down to family court and get a temporary order so she has to turn the guns over to the sheriff.
Orders of protection are kind of flawed. They are easy to abuse by going through family court and filing just to bust the other spouse's chops. They are enforced more strictly than they used to be by the police, However a lot of the time after everything is calmed down the wife goes back to the husband and then shows up in court wanting the order of protection and the criminal charges dropped-until next weekend when she'll be calling the police to come save her from another whuppin' These are very much the same cast of characters a lot of the time.
