Motion for Visitation Hearing coming up..?

She can allege whatever she wants, but most judges are used to it and don't put much stock in unsubstantiated claims. Evidence is key in legal situations. If she has no real evidence, she probably won't win. That said, ultimately, whether you cheated on her, she cheated on you, whatever the case, you have a little girl together and the focus needs to be on her well-being. Do what is best for your daughter. Part of that is getting along reasonably well with your soon to be ex wife. I know it can't be resolved today, but you really need to try to get to where that relationship can be civil if not friendly.
