Following his death, his daughters said they would remember his 'wisdom and humor,' according to Metro - Main. Catherine Falk later became an advocate for families' rights, alleging she was prevented from seeing her father during his final years due to conservatorship arrangements. She campaigned for 'Peter Falk’s Law,' which was first passed in New York and has since been adopted in more than a dozen US states. The exact date of Jacqueline Falk's death has not been released.
