Visititing mother's rights
My boyfriend has sole legal custody of his 2 year old son. The mother has supervised visitations ( the person that was ordered to be the supervisor is her sister) every Wednesday from 530 to 730 and the first three saturdays a month. When she does show up to pick their son up she is always 30-60 minutes late without a phone call. She is always very rude to my boyfriend and when he tries to communicate with her about their son, she tells him to leave her alone and not to talk to her. What rights does he have to not let her see him and if that was to happen what can she do to him to get him in trouble? Not only is this a hassle every time she shows up but it puts my own kids in front of how she is around my boyfriend. Last week she even dropped their son off with a different outfit and when my boyfriend asked her what happened she flipped him off and got in her car and drove away with no explanation. He got in the road to block her to get an answer (something I know he shouldn't have done) and she stopped pulled out a camera and took pictures. Then she drover around him and left. What can we do about her?
