help!my ex is a control freak!!!

i live in an area that is insanely expensive.
i own my own business, and can work out of the house anywhere i go. i would like to move an hour or so from where i live where the rent is more affordable. the schools are comparable. my ex is freaking out! he is threatening me to reverse custody, and is calling me a mental case and accusing me of being unstable because i want to move our kids. help!!!!!
he is telling our kids that i am evil, too.

I know in CA you have to notify the other parent, via US "return receipt request". This is to give the other parent the option of taking you to court to make changes in the custody schedule because of the move.

If the move will not disrupt the current order or the judge feels the distance is not to far to work out resonable arrangement for the children he could change the order at his own discresion.

I suggest that you research your potential move, including lots of information about schools, doctors, child care, friends and relatives in the area and make it clear that you are doing this in the best interest of your children/family and not to spite your x.

Also, make it very clear in your response that you are willing to work out the details so the children will continue to have a relationship with both parents.
