Trifle with attorney for the present (5)
I believe the answer is:
today
'the present' is the definition.
(today is a kind of present)
'trifle with attorney' is the wordplay.
'trifle' becomes 'toy' (I've seen this before).
'with' means one lot of letters goes inside another.
'attorney' becomes 'DA' (district attorney).
'toy' going around 'da' is 'TODAY'.
'for' is the link.
(Other definitions for today that I've seen before include "The present time or age" , "Presently" , "Current period of 24 hours" , "Nowadays" , "Modern times" .)
