I am moving to Canada for six months. My 15 yr old daughter does not want to move with me. Her father and I have joint legal custody; I have always had sole physical custody. My daughter would like to stay with a friend's family while I am gone. I also have an 18 yr old daughter living independently. Should my ex be named the younger one's guardian? Or can physical custody be granted to him? Does it matter? Or should the other child's parent's be guardians? Or can my 18 year-old daughter be the younger one's guardian even though they will not be living together? I want to make sure I do the right thing legally for my daughter so that she is secure and that school and medical decisions can be made for her in my absence.
