I am no expert here but I think I'd have to disagree with Jada. You are talking about what you feel is your safety, not just "their" divorce. I think you are entitled to be involved in your safety. I for one knows how it feels to be on the receiving side of a angry persons rampage... and its not fun.
I don't know much about the sharing of the property funds, but as I understand it, any asset which is an inheritance is rarely ever split unless it is gifted. If there is no "transmutation" of said assets then it is mostly his. But I am no expert. I just know that you need to do what is safest and healthiest for you and your family. But if your feelings are unwarented then you should ask someone older and wiser than you, that knows you and your family better, on what you should do. I wish you the best. I am sorry if I am not much help.
