The five-year court battle regarding legendary New York City philanthropist Brooke Astor's will has finally reached a settlement, according to her grandson, Philip Marshall. The settlement, which is to be filed Wednesday in Westchester County Surrogate Court, sets aside $100 million for charities. The recipients of the donations include the Metropolitan Museum of Art, the New York Public Library, New York City public schools, Carnegie Hall, Rockefeller University and a number of other important New York City organizations.

New York Attorney General Eric Schneiderman says that Astor's son, Anthony Marshall, will see his share of the Astor assets cut by over half- $14.5 million to be exact. When Astor passed away at the age of 105, Marshall and the charities disputed over which of the original wills and revisions best revealed Astor's true intent.

However, just years before Astor's death, Philip Marshall accused his father of mistreating Astor and sought out a new guardian for his grandmother, according to the NY Times. Anthony Marshall was eventually convicted for taking advantage of his mother's dementia to manipulate the will. 

Anthony Marshall had allegedly conspired to manipulate the will with Astor's estate lawyer, Francis X. Morrissey Jr., and the two were put on trial for months. Anthony Marshall was ultimately convicted of first-degree grand larceny after rewarding himself with a raise of $1 million for overseeing his mother's finances and Morrissey was convicted of forging Astor's signature on a revision to her will. 

The two have appealed after being sentenced to one to three years in prison.
