Court officer (7)
I believe the answer is:
bailiff
'court officer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bailiff that I've seen before include "Officer of court" , "Possibly menacing landlord's agent" , "Sheriff's officer - landlord's agent" , "Landowner's agent" , "Landlord's agent or steward" .)
