A court deed? (3)
I believe the answer is:
act
'deed?' is the definition.
(an action)
'a court' is the wordplay.
'court' becomes 'ct' (abbreviation used in road names).
'a'+'ct'='ACT'
(Other definitions for act that I've seen before include "turn" , "Feat" , "Ordinance" , "Perform on stage" , "Perform - part of a play" .)
