West Ham joint-chair Vanessa Gold says she is willing to sell part of her family's 25% stake in the club.
Gold's eldest daughter Jacqueline also died two months later, leaving Vanessa in charge of the shareholding.
She was appointed to the club's board in August by Gold's long-time business partner David Sullivan, who currently holds about 39% of shares in the club.
"I would consider selling a proportion of our shares to the right partner," said Vanessa Gold.
"I have spoken to each of the other three major shareholders at West Ham United, David Sullivan, Daniel Kretinsky and Tripp Smith, who have been very supportive.
