i am going through a divorce and i want to move out of New Jersey and my kids are living with me and my divorce is not finalized yet and i have 2 kids

Your children are old enough to have a say, and if your divorce is not finalized, then you can make it part of the divorce.  you should be prepared to say why you are moving, for example, "I have a better job in another state", or "that's where my family is from and I will have more support in raising the children and working", or whatever the circumstances are.  You cannot just say I want to move to be away from my ex !
