Hello "Lucky," and congrats. I love to hear stories like this. My advice is:
#1 DON'T TELL FRIENDS OR RELATIVES. You will have people you don't even know coming out of the woodwork, professing to be a relative. STOP! LOOK! LISTEN! TAKE HEED!
#2 Check out a reputable financial advisor and invest at least 3/4 (or more) of your $$. I know you will want to first, pay off any bills, buy a new car and/or property. But remember, property appreciates, rolling stock depreciates, so be careful. I've always heard that you should hire an attorney, but all they do is take your money. However, you know your situation, so it may be something for you to look into. If I were in your place, I'd go straight to a situation where my $$ will make $$, not take it.
Another large matter is, check on Inheritance Tax. Make sure that is taken care of first of all. That old IRS guy can get mean!
If you use a portion of your $$ to invest in a business, go it alone. If you choose to have a partner, make sure they have as much or more $$ than you. In this case, you WILL need an attorney.
Again, I'm so happy for you, and the best of luck!
