Releases, lacking right charges (4)
I believe the answer is:
fees
'charges' is the definition.
(fee is a kind of charge)
'releases lacking right' is the wordplay.
'releases' becomes 'frees' ('free' can be a synonym of 'release').
'lacking' is a deletion indicator.
'right' becomes 'r' (common abbreviation).
'frees' with 'r' taken away is 'FEES'.
(Other definitions for fees that I've seen before include "Fixed charges for professional services" , "(Membership) charges" , "Emoluments" , "Professional payments" , "Charges, payments" .)
