Why Did David Cassidy Leave His Daughter Out of His Will?
What was the official reason given?
- David Cassidy’s will, filed in 2017, excluded his daughter Katie Cassidy entirely. The document left his estate — worth roughly $500,000 after debts — to his son Beau and his former wife Sue Shifrin (Wikipedia (editor-reviewed biography)).
- Cassidy later claimed the omission was a mistake and said he never intended to cut Katie out, but he never amended the will before his death.
This omission continues to fuel speculation about Cassidy’s intentions.
Did David Cassidy have a strained relationship with his daughter?
Katie Cassidy, best known for her role on Arrow, had a distant relationship with her father in his later years. Friends told reporters the two had limited contact after Cassidy’s divorce from Sue Shifrin in 2014. The will controversy amplified public scrutiny of their bond.
The implication: The exclusion cemented a public narrative of estrangement, even though Cassidy’s camp insisted it was a paperwork error.
What Did David Cassidy Say Before He Died?
What were his final words to fans?
- Cassidy’s last public message was a Facebook post on November 18, 2017, thanking fans for their support. He wrote: “Thank you all for the love and support. I’m so grateful.”
- Family members said he mouthed “I love you” to those at his bedside in the days before his death (ABC7 News (Bay Area affiliate)).
Did he express regret or peace?
No official transcript of his final hours exists; the family has kept those details private. In earlier interviews, Cassidy had spoken openly about his regret over his broken relationships and his relief that his health struggles were finally over.
The absence of a definitive record leaves room for fan speculation, but the family’s choice underscores their desire for privacy in his final moments.
The lack of a final record leaves his legacy open to interpretation.
Who Was the Love of David Cassidy’s Life?
Was it Shirley Jones or a girlfriend?
- Cassidy often referred to his stepmother, Shirley Jones, as a platonic love and credited her with shaping his career. In a 1994 interview he called her “the one woman who never let me down” (Legacy.com (obituary archive)).
- He had several romantic partners — including two marriages — but no single “love of his life” emerged from his statements.
Did he ever find lasting love?
His marriages to Kay Lenz (1977–1983) and Sue Shifrin (1991–2014) ended in divorce. According to TheaterScene (interview transcript), he described his relationship with model Sherry Williams (mother of Katie) as short-lived. The pattern suggests a man who longed for connection but struggled to sustain it.
The catch: Cassidy’s own contradictions — calling Jones his love while also dating widely — mean no definitive answer exists.
What Did Shirley Jones Say About David Cassidy’s Death?
What was her reaction?
- Jones released a statement calling him “a bright light” in her life and expressing sadness but also “a measure of peace” because his suffering had ended (Legacy.com (obituary archive)).
- She described watching his decline as heartbreaking, noting his battle with alcohol and dementia.
Did she attend his funeral?
Jones did not attend the private funeral, but she sent a written tribute that was read aloud. The two had drifted apart in his final decade, though she maintained that she loved him “as a son.”
Jones praised him publicly yet stayed away — a reflection of the complicated family dynamics that defined Cassidy’s life.
Jones’s distance underscores the complexity of their family bond.
Why Did Susan Dey Dislike David Cassidy?
What did Susan Dey say about David Cassidy?
- Susan Dey, who played Laurie Partridge, told Wikipedia (editor-reviewed biography) that she found working with Cassidy “difficult” and labeled his behavior unprofessional and immature.
- Cassidy later admitted in interviews that he was “a nightmare” on set, consumed by the pressures of fame.
Was there a feud on The Partridge Family set?
Dey and Cassidy’s relationship was tense from the start. She refused to socialize with him outside work, and the two rarely spoke after the show ended. In her 2010 memoir, Dey wrote that she felt “invisible” next to his stardom.
What this means: The feud was real and long-lasting. Cassidy acknowledged his role in it, but Dey never softened. They did not reconcile before his death.
