If you plan on hiring an attorney to represent you in this matter, there is no reason for another attorney to give suggestions for what your attorney should possibly say in their opening statement. Also, no attorney on here is going to serve as a "backseat" counsel for someone. If your wife doesn't show up, you can request at the hearing that the TPO action be dismissed. It sounds like your marriage may be over, so I would advise, in addition to handling the TPO action, that you consider getting a divorce. Good luck.
I agree with Daniel. If you are hiring an attorney and assuming you are paying him, this kind of task is why you pay him. I am sure a lawyer near you can come up with a clever enough opening statement or he wouldn't be a lawyer very long. Good luck!
This response does not establish an Attorney-Client relationship. It is highly advised that if you wish to discuss this further that you inquire into hiring local counsel.
