Name written in property agreements (7)
I believe the answer is:
assents
'agreements' is the definition.
(I know this)
'name written in property' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'written in' indicates putting letters inside.
'property' becomes 'assets' (I've seen this before).
'n' put into 'assets' is 'ASSENTS'.
(Other definitions for assents that I've seen before include "Agrees, complies" , "Expresses agreement" , "Gives nod" , "Accedes, acquiesces" , "Says yes" .)
