Philip Seymour Hoffman left his $35 million fortune to Mimi O'Donnell.
The 'Capote' star, who was found dead in his apartment in New York City on February 2 from an apparent heroin overdose, named his estranged partner and the mother of his three children, Cooper, 10, Tallulah, seven, and five-year-old Willa, as the sole beneficiary of his estate.
A source told gossip website TMZ.com that the Oscar-winning actor wrote his will in 2004 before the birth of his daughters, and he also expressed a desire for his son to be raised in Manhattan so he could be exposed to the city's culture, arts and architecture.
The 46-year-old star also named Chicago and San Francisco as back-up places for Cooper to grow-up if his original request was impossible, and asked that his son visit both cities at least twice a year for cultural purposes.
'The Hunger Games' actor reportedly fell off the wagon in 2012 after being sober for more than 20 years and he entered rehab in May 2013.
Philip was allegedly found with around 70 bags of heroin inside his apartment after Mimi, who had recently kicked him out of their home in an act of "tough love," sent his friend David Bar Katz over to check on him when he failed to show up to spend time with their children.
Some 400 mourners, including Cate Blanchett, Julianne Moore and Diane Keaton, attended Philip's private funeral at St. Ignatius Loyola Catholic Church in Manhattan earlier this month.
