My grandfather remarried several years ago, he and she are now in their 90's and live in florida (where her family is). He wants to "come home", and we all want him close to us, but her family tells him he is home. He gets very confused at times, and they seem to be controlling him. Red flags keep going up every time we talk to her family. I guess my question is, what are their rights and our rights as far as guardianship, or taking care of him vs. whatever they have manipulated him into doing?
