In a statement, New Hampshire lottery Executive Director Charlie McIntyre said the commission consulted with the state’s attorney general’s office and that the Powerball winner must abide by the disclosure laws “like any other.”
“The New Hampshire Lottery understands that winning a $560 million Powerball jackpot is a life-changing occurrence,” the statement said. “Having awarded numerous Powerball jackpots over the years, we also understand that the procedures in place for prize claimants are critically important for the security and integrity of the lottery, our players and our games. While we respect this player’s desire to remain anonymous, state statutes and lottery rules clearly dictate protocols.” That quote was taken form article published in the Washington Post. Admins don't like sharing outside sites, so you can look it up if you'd like. Also it is required in all but 6 states (Delaware, Kansas, Maryland, Ohio, N. Dakota, and S. Carolina). Bottom line, is the state she played in does require it and for those purposes.
