Catherine Falk filed legal papers in L.A. County Superior Court claiming her father "requires full-time custodial care for his health and safety."

In the docs, Catherine claims she is worried her father "can easily be deceived into transferring away property" and believes a conservatorship will protect Peter from "fraud or undue influence."

A hearing on the matter is set for next month. Calls to Falk's reps were not returned.
