James Gandolfini is believed to be worth up to $70 million when he died of a heart attack on June 16. According to his will signed December 19 and filed Tuesday, July 2 in Manhattan Surrogate's Court, the former actor of "The Sopranos" will leave his estate primarily to his children.

Mike, Gandolfini's 13-year-old son from his first marriage, will have a trust set aside for him and will get access to it when he turns 21. The teen will also automatically get all of his late father's clothing and jewelry, and is given an option to buy one of the New York properties left by the actor.

Mike will split his father's Italian property with his half-sister, 8-month-old Liliana Ruth when she turns 25. "It is my hope and desire that they will continue to own said property and keep it in our family for as long as possible," the Emmy-winning actor states in the 17-page court document.

Gandolfini's widow, Deborah Lin with whom he had daughter Liliana, will receive the second-largest chunk of the actor's property after his kids. She reportedly gets millions from his estate. The rest will be divided among extended family members and his close friends.

$500,000 will be given to each of his nieces, $200,000 to his personal assistant and $100,000 to his godson.
