Head-holding in court (8)
I believe the answer is:
chancery
'court' is the definition.
(type of court)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for chancery that I've seen before include "Lord Chancellor's court" , "in which a wrestler may be held" , "Embassy office" , "Court of public archives" , "Where Jarndyce suit languished" .)
