Jane Doe's lawyer had asked lottery officials if she could "white out" her name and replace it with the trust name, but lottery officials said that would invalidate the ticket.
However, she also wants "the freedom to walk into a grocery store or attend public events without being known or targeted as the victor of a half-billion dollars".
"After completing and signing the ticket, Ms Doe met with counsel and learned for the first time that a trust could sign for and collect the winnings, thus preserving her privacy", says Mr Gordon.
Under regular procedures, the woman's identity would then become public when she claimed her winnings.
In New Hampshire, the woman claimed she mistakenly signed her name on her winning Powerball ticket, making her identity public information.
When the attorneys requested if she could have a trustee sign the ticket instead, with the commission present, they were denied.More news: Richardson officer hospitalized after shooting at apartment complex

New Hampshire is one of a handful of states that permit lottery winners to form anonymous trusts to shield their newfound riches. "She'll have to change her name and move away if they put her name out", said one customer. "But I found that wasn't the case", lottery victor Donna Mikkin wrote in a blog post.
A New Hampshire woman recently won $560 million Powerball, making her the world's newest owner of a nine-digit bank account.
The unidentified victor is going to court in hopes of getting her winnings while maintaining anonymity.
William Shaheen, whose law firm is representing the woman, had written a blog post shortly after the drawing, urging the victor not to sign the ticket immediately because of the confidentiality rules.
Efrain Flores narrowly missed hitting a jackpot of $103 million that day, according to Lottery officials, who said he got five of the six winning numbers in opting for the Quick Pick option.
"The lottery must proceed in accordance its rules and by state law in processing this claim like any other", McIntyre said.
