When both of my parents were gone, my brother was in charge of their estate. I am sure glad this job went to him and not to me.
My parents lived in many different states and also had property in more than one state. They were snowbirds, living in the Midwest in the summer and in Arizona in the winter. They also owned property in both of these states.
I remember my brother talking about getting a notary statement and affidavit of domicile before assets could be released.
This was quite a long process before everything was said and done. It was at least a year before all the wrinkles were ironed out. I don't think I would have done a very good job of handling the stress and details of figuring all of that out.
