If I chance my luck, considering I informed him about my intention in an email, which he did not object to (but didn't answer), and I also refer to the email in the letter with the balance, does that put me in a better position?
Also if I did chance my arm, and hold the money for a while in case he then objected - could I be prosecuted, I would never know whether he might bring this up later.
And could I be prosecuted? (and also possibly my sister as she would have become involved by being nice to me)
Sorry, just one more question. You said I wouldn't get prosecuted, and he would have to sue me in the civil courts to get the rest of his inheritance. I am not clear about the distinction - is civil court for non-criminal disputes?
