Joan Rivers' Will Revealed

— -- Joan Rivers' will, obtained by ABC News today, reveals that the iconic comedian left all her assets in a living trust.

As a result, specifics of her assets and how they will be divided will not be disclosed.

What is known is that Rivers, who died on Sept. 4 at the age of 81, named her daughter, Melissa Rivers, her longtime business manager Michael D. Karlin, and interior designer Robert Higdon as co-executors of the will, filed in the New York State Surrogate's Court on Dec. 5.

Rivers went into cardiac arrest on Aug. 28 while undergoing a procedure at Yorkville Endoscopy in Manhattan. Since then, an investigation by the New York State Health Department found the clinic deficient in four categories, though a clinic representative noted that the clinic "immediately submitted and implemented a plan of correction that addressed all issues raised."

Several weeks later, a report from the U.S. Department of Health and Human Services indicated that staff members at the clinic photographed her with a cell phone while she was sedated, improperly documented how much of the sedative propofol was used, and "failed to identify deteriorating vital signs and provide timely intervention during the procedure."

Melissa Rivers has retained attorneys, though sources familiar with her legal situation told ABC News last month that she had not yet decided whether to file a lawsuit against the clinic.

"As any of us would be, Ms. Rivers is outraged by the misconduct and mismanagement now shown to have occurred before, during and after the procedure," attorneys Jeffrey B. Bloom and Ben Rubinowitz said last month in a prepared statement. "Moving forward, Ms. Rivers will direct her efforts towards ensuring that what happened to her mother will not occur again with any other patient."
