The late Joan Rivers -- comedienne, TV host, fashion commentator and entrepreneur -- has left her family a fortune that is mostly in liquid and ready cash. Melissa Rivers has inherited a $100 million estate from her mother, and Joan also left something for her beloved grandson.

Though the amount may not seem like much to many in show business, Joan's estate is unique in that most of those $100 million is in cash rather than investments or properties. According to Us Weekly, $75 million of the total sum is believed to be in cash, sources said. Joan's $35 million Upper East Side condo makes up the rest of the inheritance.

However, the "Fashion Police" host did not leave all to her daughter. Her grandson Cooper Endicott, 13, has also inherited a trust fund believed to be more than what his mother inherited, according to the Chicago Sun-Times.

Melissa will not be strapped of cash regardless since she will continue to receive money from her mother's QVC custom jewelry money. She is also an executive producer for "Fashion Police," which airs on E!.

Joan died at the age of 81 back on Sept. 4 after she stopped breathing during a routine throat procedure at Yorkville Endoscopy, a private clinic in Manhattan. The comedienne had gone into cardiac and respiratory arrest and was put in a medically induced coma, but she did not wake up despite doctors' many attempts.

According to TMZ, Melissa Rivers will sue in an attempt to reveal the details of her mother's passing. On Oct. 16, the New York medical examiner's office released a report that said Joan had died of "therapeutic complications"; however, in accordance with the family's wishes and Jewish law, an autopsy was not performed. The New York State Department of Health released its own finding, which found many shortcomings from the clinic.

Nonetheless, to get more details, Melissa will sue to obtain sworn statements from hospital staff as to what exactly happened that lead to Joan's death.
