Hi it sounds like you need to get your daughter into therapy. Also having a licensed professional prepare a report for the Court to demonstrate,how, if at all continued exposure and contact with the father may have a negative far reaching impact on your child. In addition, although you have a hearing on the modification petition scheduled already, you can file a Petition for an Expedited hearing, which would required Family Court to schedule a hearing before a Judge to determine if the reasons you seek an expedited hearing warrant the same. Having an evaluation and recommendation by a licensed professional would strengthen your position.
Hopefully you find this answer helpful. If I can be of further assistance please feel free to email me Debra@DebraRaineyLaw.com.
