Ledger, who died in January 2008 at the age of 28, posthumously won the prize for best supporting actor for his portrayal of the evil Joker in the latest Batman adventure, "The Dark Knight." The film's director accepted the award on Ledger's behalf at the Golden Globes ceremony in Los Angeles.
"I should imagine that eventually it will be going to Matilda," Ledger's mother, Sally Bell, told People magazine. "At this stage, she is only so young, but down the track she will have all these things. It will belong to her because she is part of him."
Bell added that the late actor's family is "bursting with pride" over the accolades Heath has been earning for playing a role he "loved."
"It is such a fantastic and wonderful legacy for his daughter. Matilda will have so many people who will be able to speak to her about her father's abilities and (the) respect he had in the industry. That is such a wonderful legacy to leave," Bell told the magazine.
Matilda is Ledger's daughter by his one-time fiancee, actress Michelle Williams. The couple had broken up several months before Ledger's death of an accidental prescription drug overdose.
