Actor Bill Fagerbakke has filed for legal separation from his wife, actress Catherine McClenahan, reports TMZ.

He also recently starred on "How I Met Your Mother" as Marshall's dad. McClenahan is less well known, but she did just appear on the Jon Hamm episode of "Comedy Bang! Bang!."

The pair were married in 1989 and have two grown children -- Hannah, 21, and Carson, 18. According to the legal documents, Fagerbakke is seeking spousal support.
