David and Katie (who now stars on the TV series "Arrow") had a complicated relationship - she was raised by her mother, former model Sherry Williams - and David told PEOPLE in 2009, "Because I didn't raise her, I didn't have to parent her".
"It is my specific intent not to provide any benefits hereunder to Katherine Evelyn Cassidy and/or any descendant of Katherine Evelyn Cassidy", David wrote in the will.
Still, Katie was among the family members at her father's bedside when he died of liver and kidney failure in a Fort Lauderdale hospital on November 21.
David Cassidy leaves daughter Katie out of will. David Cassidy snubbed his daughter Katie in his will, leaving his assets to son Beau. David's three half-siblings will receive anything declared as "music memorabilia".

The Blast reports that David Cassidy took his daughter, Arrow star Katie Cassidy, out of his will sometime before his death, and it was no accident. David and Sherry never married, and five years after Katie was born, he had son Beau with third wife Sue Shifrin. I was her biological father but I didn't raise her.

He was detained after a co-worker told police that Donaldson handed her a bag with a gun inside and told her to watch it for him. A pretrial detention hearing scheduled for Tuesday was canceled because the case has not yet been assigned to a division.
Cassidy's wealth was depleted in 2015 when he filed for bankruptcy, declaring debt of up to $10 million. "She has a completely different life", he said.
Despite their differences, Cassidy said he was "proud" of his daughter for her career. "She's very talented", he said.
But David and his daughter revealed in an interview with People earlier this year that he was merely her father by biology. Katie Cassidy was raised by her mother and her stepfather, Richard Benedon.
The 31-year-old recently broke her silence about her family's loss to thank fans for their outpouring of support, revealing his last words were, "So much wasted time" - a comment which inspired Katie to "share my gratitude with those I love as to never waste another minute..."
