The types of people who know how to handle this aren't the types of people who play the lottery. But yeah, I totally agree with the top subcomment: consult an attorney. Have that attorney help you with everything, like literally everything. In fact, it might be worth getting two so they make sure the other doesn't take advantage of you and so you'll have backup in case one attorney is unavailable. Your attorney should be able to hook you up with a good financial advisor, insurance (you'll want umbrella insurance along with a bunch of other insurance you probably never knew you might need).
