I have a 10 year old son who has autism. I have 100% both physical & legal custody. His dad sees him 2 Saturday's a month and has never been to one dr. appt. or IEP meeting. He is not involved in any way other than to see him twice a month. I have had a boyfriend for the last 5 years that is thoroughly involved, as well as his family and treats him as part of their family. I am very worried about, if I should die or lose the capacity to make decisions, what will happen to my son. I want to have it in my will that my boyfriend be his legal guardian, while his dad will still remain his dad and visitation would not change. How would I go about doing this?
