Joan Rivers spread her estimated $150 million fortune among family, friends, staff and charities — including a group that supports guide dogs, according to the comedienne’s will filed Tuesday.
But the document is devoid of details, leaving all the money to the beneficiaries through a blind trust.

Rivers’ only child, Melissa, who was named an executor of the estate, also will get all of her mother’s tangible property.

Other family members set to inherit unspecified amounts are Melissa’s son and Joan’s grandson, Edgar Cooper Endicott, and Rivers’ niece and nephew, Caroline Waxler and Andrew Waxler.

“We didn’t know,” gasped Andrew’s wife, Laurie Waxler, when told of the inheritance by The Post. “She was an incredibly generous woman.”

Rivers’ close staff, including assistants Jocelyn Pickett and Sabrina Lott Miller and publicist Scott Currie, also received bequests.

Miller, one of five staffers named in the will, said her employer of 26 years was “generous to a fault.”

Currie, a close friend of Rivers who planned her memorial service, said his undisclosed inheritance doesn’t ease the pain of the comic genius’s passing.

“Nothing can ever make up for the loss I feel every day,” Currie said.

“She was such a big part of my life for over 25 years. She was an incredible lady.”

A source close to the family said Rivers “was great to her staff, and they loved her.”

“I know that she put some of their kids through school,” the source noted.

In addition, Rivers showered funds on her favorite charities: Guide Dogs for the Blind in California; the Queens-based food pantry God’s Love We Deliver, where Joan was a board member; the Jewish Guild for the Blind in Manhattan; the Simon Wiesenthal Center; the Cystic Fibrosis Foundation, where Joan served as a spokeswoman; and the Jewish Home and Hospital Foundation in Manhattan.

The legal filing makes a brief mention of a forthcoming medical malpractice suit over Rivers’ death at age 81 after a procedure on her throat in September.
