no because them you wold be in contempt of court. you cannot physically keep her from him unless you have a court order from a judge.
You go to court.
Not if the father is doing his fatherly duties for the children, and causing the children no harm or pain. But if he is then yes, also if she sees the father unfit and suspects harm is being done in which case it should be taken to court.
Not unless she has a court order.
A father was jailed for calling his daughter "she" because he violated a court order that required him to refer to her using gender-neutral terms.
Through court actions, but not on her own.
As a wife you do, but if nothing has been said in court, then according to the government, the answer is no.
If by withholding the information she is preventing him from seeing the child she is in contempt of the court order.
Not without it clearly stated in the court order.
He doesn't. Only the courts can award/enforce visitation.
If the mother have visitation right granted by the court the father can not stop her from seeing her child. If he does she can get help from the police and also report him back to the court so they know he broke the court order.
I don't know your situation, but you can do anything as long as both parties agree. What I mean by both parties is mother and father. If mother and father agree, and the 16 year old wants to live with her father for a year, then it is OK. If the parents do not agree, then a court hearing may be necessary to hear both sides and decide what is best for your daughter. Being that your daughter is 16, she will have some say in court as well.
I have seen no documentation that disallows a father from representing any relative in a Federal court case.
