Roz, what you need to do is make sure that both of you get (joint physical custody) also make sure that it is stipulated that neither one of you can move out of the county/city without giving up custody of the minor children. In the event of job transfer,marrage,what ever the essue may be that parent will give up its custody rights of the child/children. I lost my daughter when she was only 4 when her mother had been seeing our neighbors best friend who at the time was living in the bay area/Berkley. She then decided to move there and the corts aloud it. They then tried to move to Germany because of a job, I was able to stop that because it was a non English speaking country. They decided to move to England which the courts granted. I never gave up on my daughter and our relationship. She is now going to be 15 this month and has been living with us for the last 3 1/2 years. If you like more details and more information and ideas that might help you in your situation please do not hesitate to call me at 209-471-7199 leave a voice message and how I can get back to you. I will call back.
good luck and dont give up on yourself and your daughter.
