I was her biological father but I didn't raise her. In addition, the former "Partridge Family" star left his music memorabilia to his half-siblings Shaun, Ryan and Patrick.
David Cassidy's only daughter, Katie, has been cut out of his will and will inherit nothing following the death of the teen idol.
She once recorded her dad's classic song in 2002 when she was 16, but behind the scenes, the bond between father and daughter was a shaky one. Cassidy also has a son, Beau Cassidy, 26, with his third wife Sue Shifrin.
The last will and testament of David Cassidy has now been released, and many are shocked to discover that he has omitted his daughter Katie Cassidy from receiving any of his estate.
"I've never had a relationship with her", the elder Cassidy told PEOPLE in a February interview, shortly after revealing his battle with dementia.
It is important to point out that the will was filed in 2004 and David shared a tumultuous relationship with Katie, an actress best known for her portrayal of Laurel Lance, the alter ego of Black Canary on The CW's Arrow.
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".
"She has a completely different life", he told the magazine. "She's very talented. It's hard for me to even accept how old she is now, like 30".
Katie has appeared in TV series such as Arrow, Gossip Girl and Supernatural.
Despite this, the two had a relationship and she was among those by his hospital bed when he died, tweeting days later, "My father's last words were "So much wasted time".
When he passed, Katie publicly paid tribute to David, writing: "Words cant express the solace our family's received from all the love and support during this trying time".
