My father recently passed away. He was not married, there is a will, my only sibling and I are the beneficiaries, and I am the executor. He owned no property, and had little to no debt, as far as we can tell. He owned 3 vehicles, and had an investment account, on which I am a joint account holder. About half of that is allocated in the will to college funds for grandchildren. My sibling and I are not disputing or fighting over any of this. Are there any legal actions we are required to take, do we have to go into probate, or can we sell the vehicles, split what is left in the investment account, and let it go at that?
