Customer gets charge in court (6)
I believe the answer is:
client
'customer' is the definition.
(synonyms)
'charge in court' is the wordplay.
'charge' becomes 'lien' (I am not sure about this - if you are sure you should believe this answer much more).
'in' is an insertion indicator.
'court' becomes 'ct' (abbreviation used in road names).
'lien' placed within 'ct' is 'CLIENT'.
'gets' is the link.
Can you help me to learn more?
(Other definitions for client that I've seen before include "Eg, lawyer's customer" , "Person represented by lawyer" , "Computer software" , "Buyer" , "Customer of professional person" .)
