Risky to circumvent the Queen's court (8)
I believe the answer is:
chancery
'court' is the definition.
(chancery is a kind of court)
'risky to circumvent the queen's' is the wordplay.
'risky' becomes 'chancy' ('chancy' can be a synonym of 'risky').
'to circumvent' is an insertion indicator.
'the queen' becomes 'er' (Elizabeth Regina).
'chancy' going around 'er' is 'CHANCERY'.
(Other definitions for chancery that I've seen before include "He can cry (anag.)" , "Division of the British Court of Justice" , "Public record office" , "Court of public archives" , "Where Jarndyce suit languished" .)
