What is the name of your state (only U.S. law)? New York
what consequences would a woman have if she moved out of state with her children if she had sole custody after a divorce judgement was awarded? My friend is trying to leave NY to CA for a bette job in the nursing profession and was told by others, that she couldn't do it without consent from her ex. Is this true? What is to stop her from doing it.What is the name of your state (only U.S. law)?
The court will make custody decisions based on what is better for the children. Generally, the premise is that the children are better off with regular contact with both parents.
If she decides to move without her ex's permission, he could immediately go to court and ask for a court order to have the children returned to NY. The court might grant it. It's impossible to say how it would go, but the factors which would probably enter into it revolve around the amount of time the kids spend with each parent.
The more time the kids are spending with their father now, the better his chances are of blocking the move. The longer the kids have been in their current situation, the better the chances of blocking the move. And so on.
If there were an abuse issue and there was a court order against the father, this would, of course, change, but you didn't say anything about that.
Even if the parents can agree, they should get the court to approve it before she moves because he can always change his mind if there's no court order.
And there's a very good chance that she's going to be paying for the kids' transportation for regular visitation. If she's currently in upstate NY, the cost of living in CA will be much higher. If she's in the city, it will be more comparable. In any event, the 'better' job might end up not being as much of a benefit as she thinks.
In general, it's disruptive to the kids' lives and interferes with their relationship with the father. There are studies which show that one of the largest factors that determines how kids do later in life (career, staying out of jail, etc) is their relationship with their father (probably their relationship with both parents, but the study mostly involved kids who already had a strong relationship with their mother).
Bottom line is that you really need to think long and hard about it and I would recommend against it both for legal reasons and for the benefit of the kids. But if you do it, anyway, your ex could challenge it - and have a good chance of winning custody.
