Hmm... Ohio is quite far away. I'm estimating that it's about $600 USD for a round-trip back and forth on the same day (I used Orbitz): SD, Ca from Cleaveland, OH, round trip same day. I still stand with my opinion, which is to make a motion to vacate and dismiss (it's a simple legal form), and generate an evidence-based argument (witnesses, too, if applicable) as to why it should not continue: This is in case she shows up. Also, it would be wise to deny having ever knowingly talked to the person on the restraining order: You may want to research applicable telephone laws for CA, WA, and OH. You don't absolutely know you had a telephone call with her, right? She would have to use civil discovery to prove that you called her. heh, yeah, I feel the haters coming on here. That phone call is something you would have to take into consideration. I think I've read there is a six month statute on violations, which is something you might want to look into. You might even want to hire a cheap attorney to resolve this while bringing all evidence and witness statements so the attorney knows the argument (gameplan) ahead of time.
What I'm recommending is a gamble rather than hiring an attorney. And in a lot of ways, if you keep making motions to vacate and dismiss (and make sure something significant happens, if you can; perhaps you went to therapy, per se), and the ex-wife is going to have to make another round trip or pay an attorney $500 USD.
Do you see what I'm recommending here?
I'm recommending economic warfare. lol.
If the ex-wife attempts to assign someone as power of attorney, then if it's not legally legit, object to it and continue to seek a vacate.
