As the only heir at law, I sure would consult a GOOD probate lawyer to see if it can be successfully contested. At $1 million, knocking it out gets you something far more than the pocket change, but depending on how the Will was drawn, if you don't knock it out you may lose that pocket change. The grounds for contesting it are set out on FreeAdvice.com under Wills and Probate.
The fact that someone is an alcoholic does NOT mean that he lacked menatl capacity to prepare a Will, or that he was the subject of undue influence, fraud, duress, etc. BUT in the hands of a good lawyer who can investigate and possibly raise questions, the lucky friend may be willing to settle or risk losing everything.
