Money posted in court (4)
I believe the answer is:
bail
'money posted in court' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bail that I've seen before include "One of two on the stumps" , "Wooden bar" , "Piece placed on top of cricket stumps" , "Piece of sporting apparatus" , "Temporary release of one awaiting trial" .)
