Needs me to sort out estate (7)
I believe the answer is:
demesne
'estate' is the definition.
('demesne' can be a synonym of 'estate')
'needs me to sort out' is the wordplay.
'to sort out' indicates anagramming the letters.
'needs'+'me'='needsme'
'needsme' with letters rearranged gives 'DEMESNE'.
(Other definitions for demesne that I've seen before include "Seed men on landed estate" , "Large landed property" , "Domain" , "Extensive landed property" , "Landed property used by the owner - needs me (anag)" .)
