My ex husband and I have the standard custody arrangement. I have physical and we have joint legal. He has the right to visitation for one non consecutive week at a time for up to six weeks a year. Up until about three weeks ago, he only chose to visit our children twice a year and never had any contact with their school or never showed any interest in being there as far as legal custody goes. Since he got out of the military three weeks ago, he has been harrassing my childrens school, (which for the last four years never called once). He tried to set up a day to go to the school on the last day of school right before the end of class and do a "presentation". Which is weird in and of it self because he lives over twelve hours away. I am extremely uncomfortable with this. I spoke with a lawyer and they said because he has joint legal custody he has the right to do this. It is terrifying my children and was so strange that my son's teacher approached me after school. What should I do???? He has threatened in the past to come and take my children, I keep looking over my shoulder expecting them to be gone....
