David Cassidy, who starred on the TV show “The Partridge Family” chose to cut his daughter out of his Will, so she will not receive an inheritance from him, according to the Los Angeles Times in "David Cassidy cut daughter Katie Cassidy out of his will."
David Cassidy previously acknowledged that he had never had much of a relationship with his daughter. She was raised by her mother and stepfather and rarely saw her biological father. David regretted this and the two reconciled before he passed away. However, David never changed his Will and Katie was specifically excluded from her father's prior Will (signed in 2004). The open question is whether David never got around to changing his Will to include his daughter after their reconciliation.
Your Will and other estate planning documents should be reviewed and updated whenever you have had a meaningful change of circumstances in your life. Most people have had a sufficient “change of circumstances” in their life at least every 5 to 10 years to warrant a review of their existing estate plan.
