I have a cousin that told me she was going to file something (in Iowa) that is similar to VPO. The net result was that her ex would be unable to possess firearms until the VPO expired, or he could prove otherwise and then get them back. I was surprised and asked "do you really think he'll do anything"? She said no. I said as in no chance? She said yeah. Apparently what caused their end was him cheating. Like most of us here, he liked firearms and was a hunter and collector. This was going to be a revenge act. I told her that I wouldn't do that. I said if I were in his shoes and that happened, I'd be LIVID. I said I'd fight her for everything in court. Child support, property division, etc. where otherwise I'd probably just realize I probably caused it and let her have more than my share. Thankfully, she saw my point and didn't follow through with it. A few years later those two even dated again for a while but ultimately it sounded like the wounds were too deep. However, this whole interaction with a person I know fairly well, and that I wouldn't have thought had a vindictive bone in her body, has left me realizing just how easy it could be.
There are some unscrupulous divorce lawyers out there who advise all their female clients to file VPO's as a bargaining chip. IMO they should be censured and if they persist, disbarred if that can be proven.
