Coy dean forking out when judgment's announced (3,2,9)
I believe the answer is:
day of reckoning
'when judgment's announced' is the definition.
(day of judgement)
'coy dean forking out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'coy'+'dean'+'forking'='coydeanforking'
'coydeanforking' with letters rearranged gives 'DAY OF RECKONING'.
(Other definitions for day of reckoning that I've seen before include "Time to fulfil one's obligations" , "When to pay for past" , "24 hours of audit?" .)
