The complaint filed Monday in a Los Angeles Superior Court asks for at least $1,000,000 in damages and charges Laura Boyce with violating a confidentiality agreement, defamation and infliction of emotional distress on the former "West Wing" star, his wife Sheryl and two sons.
Boyce was hired to take care of their sons for most of 2007 before she quit in November, according to the complaint.
It was not clear whether Boyce had hired an attorney. A message left at a phone number listed in her name was not immediately returned.
Lowe is currently appearing on the ABC show "Brothers and Sisters" and was in the films "Wayne's World," "St. Elmo's Fire," and "The Outsiders."
