I live in PA and ex lives in Nebraska, divorce and custody were both ordered in NY. His wife does not like our children and has done everything in her power to be sure there is no communication between the children and thier father. Her newest trick was to change thier home phone number to an unlisted number. My children are furious. My son tried to call his father 2 weeks ago and found out the number was now unlisted. It was not changed because of me because in the 13 yrs we have been divorced I have called him MAYBE 5 times and each time was directly related to the childrens health. (ie: son being admitted to the hospital) Is there any recourse here?
