Claim on property (4)
I believe the answer is:
lien
'claim on property' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lien that I've seen before include "Right to another's property, if an obligation is not discharged" , "Security for a debt" , "Legal right to detain property" , "Right to retain property until a debt is paid" , "Legal claim on the property of another" .)
