Are there court papers which outline visitation rights and if the mother has been granted visitation rights by the court how is the visitation to be handled? Anything ordered by the court has to be followed or the father of the children has to go back to court to have the order changed. I suggest that even if visitation is not specifically addressed in the order it can still be required if the mother pushes for it. I think that the only time visitation would not be required is if the order states that there will be no visitation.
The children's father needs to take the court order to an attorney for advice before he does anything else.
If the mother volunarily relinquished her parental rights the situation is different. Once rights are relinquished the parent has no rights re: the children. However signing over custody means that she has only relinquished custody and she continues to have other rights. This is an important difference that needs to considered.
An attorney should be able to help answer the visitation requirment if it's not clearly stated in the court order.
I agree that sending the children to another state to visit an absent mother and a step-father that no one in this state knows is a bad idea especially when the children strongly object to going. Has your son tried to work out a compromise with his ex?
Once the father knows his children's mother's legal standing in regards to the child(ren) he can then decide how to handle the visitation in a legal manner. If visitation in the other state is legally required then he should talk with a mental health professional who deals with visitation issues to see how he can best help his children while not alienating their mother.
Because she is their mother she is an important part of their emotional well being even if she's inappropriate in many ways. I'm glad to read that they have been having some visits and that you and their father have facilitated them.
I agree with others who've suggested that a trusted adult go with the children or be their primary caretaker while the children are visiting or that the mother and her new husband visit here. Since they have visited other relatives when they visited with their mother would a relative living in that city be able to "supervise?"
This is a difficult situation! I think that the most important factor is maintaining a reasonably good relationship between the mother and her children. Since I don't know any of you I do not know how this can be done. A point blank refusal to send the children is not the answer.
