New Hampshire Lottery Commission rules require a winner sign the ticket before being able to claim a prize.
If she had signed the back of the ticket with the name of a trust, she could have maintained her privacy. However, her attorney, Steven Gordon, wrote in court filings obtained by The Union Leader that she didn't realize she had that option until after the fact.
“Her attorney asked if she could ‘white out’ her name in front of lottery officials and replace it with the trust, but was told any alteration would invalidate the ticket and she'd lose $560 million,” the newspaper reported.
The lottery executive director said those rules are in place for security reasons.
