If you have minor children, then your failure to cooperate may cause CPS to decide to take the children into custody and ask the juvenile court
to restrict your custody/visitation
-- or, place the children in foster case or under the care of someone else.
Whether or not this would actually occur is unknown.
A not guilty verdict in a criminal case means that the prosecution did not prove its case beyond all reasonable doubt. A juvenile and/or civil court action has a much lower burden of proof, so it's possible to be not guilty in criminal court, and liable in juvenile or civil court.
In my opinion, you may want to consider allowing the meeting, but not saying anything. And, if things get too adversarial, you can simply state that "I respectfully XXXXX XXXXX answer the question, and this meeting is concluded."
