I have 4 children and one child lives with my ex and the other 3 children and the youngest child had a rare medabolic disease and she needed a liver transplant and I had to get his visition limited to a few hours ever other weekend and he has never gotten her she is only 8 and now really doesn't remember him. The 2 oldest haven't seen him in over 8 months he did show up at christmas and brought them gifts but has not seen them since he has only texted 1 time to get them but it was not his weekend it was mine and I did not let them go because it was the wrong weekend and I have not heard from since and I have not seen my oldest child since christmas because she does not want to see me because of thing that she has been told So my Question is what can I do to just stop all his visistion rights as he doesn't use them and I don't want him to come back and hurt them again like he already have in the past

If there is a visitation order in place, go back to family court and ask for a modification, by presenting evidence that he is not exercising his visitation rights, and that you have not blocked his attempts to exercise those rights. The outcome depends on the strength of your evidence, whether he fights you, and the mood of courts in your area regarding custody.

You will have to go back to court, and ask the court to modify the order. Next you will not stop his "rights" he will have rights to always take you back to court latter and try to modify them for his benefit. You may get his time reduced, but then he may counter file to ask for more time to be given, esp if the children's health improved or he can care for the condition.

I'm afraid it's a legal matter, it will have to go back to the courts.I can sympathize with what you are saying but he is the father.It will be down to the courts to decide whether or not it will be in the children's best interest to have visits from their father depending on supportive evidence from both parties.
