My boyfriend died on January 3, 2004 at home with me under care of a Georgia hospice. He had a living will with me named and also a health care POA for me. I was able to make all decisions EXCEPT for one. He wanted to be cremated. The Georgia funeral home said they "could" take his brother's signature for approval of cremation, but that they really wanted his son's. (they were estranged). The funeral director had to call the son in California and they faxed back and forth with the son giving his permission for cremation.
Thanks for your touching story. I had a very dear friend who was in a similar situation. She's at peace now as I'm sure your friend is. Bless you.
