A deal that brings father to court (4)
I believe the answer is:
pact
'a deal' is the definition.
(I've seen this before)
'father to court' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'to court' becomes 'ct' (abbreviation used in road names).
'pa'+'ct'='PACT'
'that brings' acts as a link.
(Other definitions for pact that I've seen before include "Alliance" , "deal" , "Written agreement between two states" , "International treaty" , "Settlement" .)
