This answer does not, nor is it intended to, create an attorney-client relationship or constitute attorney advertising. Rather, it is offered solely for informational purposes. The facts of each case are different and unique, it is critical to consult with qualified counsel with whom information can be shared and assessed under attorney-client privilege, so that competent and quality advice can be obtained on which you can make informed decisions

Since you say that it was the "final hearing," I'm guessing you had a Consent Agreement signed so this witness didn't impact anything, did he/she? Whatever the case may be, your divorce is in Ohio and you'd be best to post your question in the Ohio forums.
