TLDR: Peter Falk was diagnosed with Alzheimer’s disease in 2008 and placed under the conservatorship of his wife Shera Danese.
His adopted daughter Catherine Falk sued for the right to visit him after she alleged Shera was blocking access.
A court granted Catherine supervised visits of 30 minutes every other month.
After Falk’s death in 2011, Catherine turned her grief into advocacy, successfully lobbying for laws in multiple states that prevent conservators from cutting families off from ailing relatives.
They are known as Peter Falk’s Law.
The final chapter of Peter Falk’s life was defined by the same qualities that made Lieutenant Columbo so compelling: a story that looked simple on the surface and turned out to be far more complicated underneath.
When the Decline Became Undeniable
By the mid-2000s, those close to Falk had begun noticing memory lapses.
His decline accelerated sharply in late 2007 following a series of dental operations, after which his physician observed a rapid and severe deterioration in his mental capacity.
A hip replacement surgery in 2008 made things significantly worse. By that point, Falk could no longer recognize family members, could not recall major events from his own life, and had lost all memory of his four-decade career as Columbo.
In April 2008 he was photographed wandering in apparent confusion near his Beverly Hills home, prompting bystanders to call emergency services. Two months later he lost control of his vehicle and drove into an office building.
The Conservatorship Fight
In December 2008, Catherine Falk filed a petition in Los Angeles County Superior Court seeking to be appointed her father’s conservator.
The filing publicly confirmed for the first time that Falk had Alzheimer’s disease.
Catherine alleged that her stepmother Shera Danese had been systematically preventing her and her sister Jacqueline from visiting their father since Father’s Day of that year.
To support her case, Catherine’s legal team presented hundreds of postcards and telegrams Falk had sent her during his years traveling and filming, evidence of what she described as a close, loving relationship with her father.
Shera’s defense countered by submitting Falk’s personal diaries into evidence, arguing that his relationship with Catherine had been historically difficult and estranged.
Shera’s attorneys also pointed to a 1992 lawsuit in which Catherine had sued her father to enforce his divorce obligation to pay her college tuition at Syracuse University, a legal action that had driven a significant wedge between them at the time, even though Catherine testified they had since fully reconciled.
The two-day trial was heard in June 2009 before Probate Judge Aviva K. Bobb.
Falk’s physician, Dr. Stephen Read, testified that by then Falk’s Alzheimer’s had progressed to the point where he would not recognize Catherine or retain any memory of visits.
Despite this, the court ruled that Catherine had a legal right to see her father.
What the Court Ordered
Judge Bobb appointed Shera Danese as the conservator of both Falk’s person and his estate, affirming that she was his designated caregiver under documents he had executed in 2005 while still cognitively healthy.
But the judge also ordered a mandatory visitation schedule over Shera’s objections: Catherine was granted one 30-minute visit every other month.
The visits were required to take place at the home of a family friend located near the Falks, and entirely outside Shera’s presence.
Falk spent his final two years in this arrangement, living under 24-hour care in a guesthouse at his Beverly Hills property. He died on June 23, 2011, at age 83, from pneumonia and Alzheimer’s complications.
Shera did not notify Catherine or Jacqueline of his final hospitalization, his death, or his funeral arrangements.
The daughters learned of their father’s passing through media reports and were barred from attending his burial.
The Will and the No-Contest Clause
Falk’s estate was valued at approximately $5 million at the time of his death. His will left the majority to Shera, with explicit provisions setting aside six-figure bequests for both daughters.
However, the estate documents also contained a no-contest clause stating that if either daughter legally challenged the will or its administration, they would forfeit their inheritance entirely.
Catherine challenged elements of the estate distribution in court. The probate court upheld the no-contest clause, and Catherine forfeited her bequest.
Peter Falk’s Law
Rather than retreating from the experience, Catherine Falk turned it into a legislative campaign.
She founded the Catherine Falk Organization and began advocating for state laws requiring conservators to provide family members with notice of a ward’s hospitalizations, health changes, and death, and guaranteeing adult children the right to visit ailing parents under conservatorships without requiring a separate court battle for each visit.
The resulting legislation, known informally as Peter Falk’s Law, passed in several states with bipartisan support.
New York enacted it in 2016, signed by Governor Andrew Cuomo. California, Texas, and Iowa also passed versions of the bill.
Catherine testified before multiple state legislatures, often appearing alongside Kerri Kasem, daughter of radio personality Casey Kasem, who had experienced a nearly identical dispute with her stepmother over her father’s final years.
The tragic irony of the case was not lost on those who followed it. Peter Falk had filmed a public service video in 2003 urging banks and healthcare workers to recognize and combat elder financial abuse, motivated in part by his own mother having been victimized by a caregiver.
Less than a decade later, his own family became a case study in the kind of guardianship isolation those laws were designed to prevent.
Jacqueline Falk, the quieter of the two sisters who had stayed largely out of public view throughout the dispute, died in April 2026 at age 60.
Why did Peter Falk’s daughter sue him?
Catherine Falk’s original 1992 lawsuit against her father was to enforce his divorce obligation to fund her college tuition at Syracuse University. Her 2008 conservatorship petition was a separate action seeking the right to visit him as he declined from Alzheimer’s disease.
Did Peter Falk have Alzheimer’s disease?
Yes. Falk’s Alzheimer’s diagnosis was publicly confirmed in December 2008 through court filings by his daughter Catherine. His physician testified that by mid-2009 his cognitive decline was so advanced that he could not recognize family members or recall his own career.
What is Peter Falk’s Law?
Peter Falk’s Law is the informal name for legislation passed in several US states, including New York, California, Texas, and Iowa, that guarantees adult children the right to visit ailing parents under conservatorships and requires conservators to notify family members of hospitalizations and death.
