How can you remain anonymous after winning the lottery?
Actually, your best bet is to sign the back of the ticket and put it in a safe place. Then go find yourself a good lawyer and have the attorney set up a trust with a bank. The trust will need a name. Let's name it the " BigWin Trust". Once BigWin Trust is properly set up the lawyer will have one of the bank officers present the winning ticket to the lottery agency and accept the winnings on behalf of the BigWin Trust. This is legal in the states that have Powerball. Not sure about Megamillion states. But, sign the ticket, put it in a safe place, see a lawyer, set up a trust and then keep your mouth shut and no one will ever know.
Powerball web sites states the following: "All but five states (DE, KS, MD, ND, OH) have laws that require the lottery to release the name and city of residence to anyone who asks. Other states may offer to assist you in some way, including such things as the creation of trusts. But generally, you will want to hire an attorney to review the laws in your state to see what options you might have. Photos and press conferences are up to you for most, but not all states. Check with your state lottery to see if photos or more are required. Most of the time, it is advisable to get it over with the press so that you don't have one or more reporters following you around to get that "exclusive" interview. Even if the you can keep your identity secret from the press and the public, you will have to be known to the lottery - so they can confirm that you are eligible to play and win."
