The verdict was returned Tuesday in a lawsuit filed by Scott Howard. He claimed he had an oral agreement with the actress and was owed a percentage of her earnings on the hit NBC sitcom.
Howard worked with Kudrow for 16 years, beginning in 1991.
Kudrow contended during the trial that she paid Howard more than $11 million before they parted ways in 2007.
Kudrow's attorney, Gerald Sauer, says the verdict will be appealed.
Kudrow starred on "Friends" from 1994 to 2004.
City News Service says trial testimony indicated she earned more than $1 million per episode by the end of the show's run.
