New documents allegedly filed by the executor of Carrie's will claim that Billie is the sole beneficiary of personal property left by the Star Wars actress.
It is possible that Billie's inheritance will be even larger as Carrie could have had additional funds in trusts that would not necessarily be included in the probate filing.
A handful of Fisher's memorabilia will be auctioned in September and her shared property with the late Debbie Reynolds is on the market for $18 million.
The 25-year-old actress wore a black top with a dress with glimmering gold embellishments and her wavy blonde tresses parted and down, coordinating with gold heels and gold hoop earrings. The said amount will most likely go into the late actress' trust. In The Last Jedi, sadly, fans will also be saying goodbye to Leia Organa due to the sudden passing of actress Carrie Fisher late past year.
Just a day after the actress' death, her mother, Debbie Reynolds, passed away at the age of 84. Fisher's daughter will also inherit personal belongings like jewellery, artwork and collectibles.

The 62-year-old was in poor health and wrote letters to his friends stating he had stomach pain and high blood pressure. A family spokesperson says his health was deteriorating, and he lost an excessive amount of weight while in detention.
Earlier this month, Billie Lourd opened up about how she's coping with the loss of her mother and grandmother.
"If life's not amusing, then it's just true - and that would be unacceptable".
The star was incredibly close to her daughter. The cause of death on her death certificate is cardiac arrest. "...and now is the first time in my life when I get to own my life and stand on my won", she told her "American Horror Story: Cult" co-star Sarah Paulson in a Town and Country magazine interview.
Although Billie knows she was out-shone by Carrie, she "loves" being known as the daughter of Princess Leia.
However, Billie feels there is "a lot of pressure" on her to continue Carrie's "incredible legacy".
