Trying To Put Dad To Rest In Peace

My father passed away unexpectedly while I was across the country on August 2. Since I’ve been home, the rest of his immediate family has done nothing to assist in getting him cremated, and he was left in a morgue for over a week. His sons were nice enough to call to have him moved to a funeral home, excluded me from the obituary, and won’t use any of the bond money he left them to cremate him. I wasn’t left anything, and I’m fine with that. But I’m not fine with letting this continue any longer. I’d rather just not deal with the people he is related to. His best friend and I are arranging a private service for later on in the week, for neighbors and friends. Any help would be MOST APPRECIATED
