Only if he invested well and you inherited his estate.
It's a bitter pill. I was subjected to a similar fate with a relative of my relative who supposedly left me his estate. I had been too unwilling to seem grasping to ask him for a copy of the will or the name of his lawyer. Whoops! Another relative had a key to the deceased's house because her son was doing repair work for him; and suddenly, no will could ever be found.
