Subway fans have until Friday to win free subs for life, but the catch will require some legal fees

• Subway's latest change will grant one fan free sandwiches for life.
• Hopefuls must legally change their name to Subway by Thursday night to enter the contest.

Subway is promising free sandwiches for life to one lucky fan, but they'll have to make a pretty permanent change to qualify for the deal.

You have until Friday at midnight to legally change your first name to Subway if you want to score free sandwiches for life from the chain, according to a press release. Fans can visit SubwayNameChange.com to enter starting Tuesday.

"Subway brand love and dedication run deep, especially when free sandwiches are up for grabs," the announcement read. "In 2022, one superfan camped out for two days to get a footlong tattoo of the Subway Series logo in exchange for free Subway for life."

The winner will also be reimbursed for the legal fees of changing their name. Earlier this month, Subway introduced its Deli Hero subs made with meat sliced in-house to 20,000 US locations, and it pledged to give away one million six-inch subs.

The sandwich chain began overhauling its menu with new ingredients and sandwiches in 2021. According to the press release, 2023 is the third year of Subway's "multiyear transformation journey."

If you're considering entering its latest contest, no purchase is necessary, but it's only open to legal US residents ages 18 years or older, with higher age limits in Alabama, Nevada, and Mississippi.

Subway did not immediately respond to Insider's request for comment.
