If you are entitled to an order of protection and the threats and harassments are happening in front of your child, and you believe that a danger presents itself to your child as well, you might be able to have the order modified to include your daughter. You should speak with the DA that is handling the matter. If you are filing a petition then this is a family court matter. The court clerk should be able to assist you.
you should pursue this matter with the police if you feel threatened or harassed. It may become a he said/she said but the police and/or the family court should get involved.
