Auditor’s seen in place (5)
I believe the answer is:
sited
'in place' is the definition.
'auditor's seen' is the wordplay.
'auditor's' shows a homophone (sound like).
'seen' becomes 'sighted' (I've seen this before).
'sighted' sounds like 'SITED'.
(Other definitions for sited that I've seen before include "Situated" , "Positioned" , "installed" , "Put" , "Placed, located" .)
