Right out of line (4)
I believe the answer is:
lien
'right' is the definition.
(I've seen this before)
'out of line' is the wordplay.
'out of' is an anagram indicator.
'line' is an anagram of 'LIEN'.
(Other definitions for lien that I've seen before include "Legal claim on Nile" , "Right to a lawyer" , "Right to retain property until a debt is paid" , "The right to take property if an obligation is not met" , "Sequestration order" .)
