You've won...now what.

Do you play the lottery? Have you ever won? If so, after you jump up and down, scream and hug everyone in site, there are a few things you should do.

Keep that ticket safe. Sockman says people do funny things with their tickets, such as keeping it in a baggie in the freezer, in a sock under the mattress, in a money-belt around their waist day and night, or most practical of all, in a safe deposit box.

Think about your job. A winning ticket is a grand thing, but it doesn't really count until you've got the cash. For now, consider just taking a little sick time or vacation, without explaining why, if possible. You're going to be very busy becoming a millionaire. You probably will quit eventually. Sockman says most winners do, even though at their original interview about a quarter claim they'll keep working. He explains, "They can't imagine how much money they've won. It's a life-changing event."

Find people you can trust. "The most important financial decision to make initially is who's going to be accountant, financial adviser and lawyer," says Hartigan. "And I don't think they should be the same person." If you don't have all of these people in your Rolodex currently -- and how many of us do? -- "talk to other people who use these kinds of services. Referral is the best way," Hartigan suggests. If none of your friends or family can recommend a particular professional, Hartigan recommends going to a major accounting firm, a major brokerage and a large law firm. "Ask what they'll do for you." Garrison agrees with Hartigan's advice and adds, "References are mandatory."

Decide on a lump sum or payments. This decision depends on what you want to do with your money and advice from your team of advisers. The lump sum will equal less than the total of the payments over however many years. "With the lump sum invested properly, you'll probably have more at the end," says Hartigan. "If you're a person who really can't control your spending, annual might be better." In Florida, the recent trend shows 75% of winners take the lump sum, says Sockman.

Arrange for a special account at the bank. You can't just deposit millions into your plain ol' checking account. And they don't really give you a paper check with a lot of zeroes. They give you the money by a wire transfer to your pre-arranged special account, says Sockman.

Change your phone number. Now that you're richer than your wildest dreams, everyone's going to want to reach out and touch you, and that will be a nightmare. So get a new unlisted telephone number.
