Disturbance in court, perhaps (7)
I believe the answer is:
ruction
'disturbance' is the definition.
(I know that ruction is a type of disturbance)
'in court perhaps' is the wordplay.
'perhaps' indicates an anagram.
'in'+'court'='incourt'
'incourt' is an anagram of 'RUCTION'.
(Other definitions for ruction that I've seen before include "Racket" , "Find a disturbance in cut iron" , "Uproar" , "Disturbance, quarrel" , "In court (anag.)" .)
