Estate needs to be reorganised around this person (7)
I believe the answer is:
demesne
'estate' is the definition.
('demesne' can be a synonym of 'estate')
'needs to be reorganised around this person' is the wordplay.
'to be reorganised' indicates an anagram.
'around' indicates putting letters inside.
'this person' becomes 'me' (I've seen this in other clues).
'needs' is an anagram of 'desne'.
'desne' placed around 'me' is 'DEMESNE'.
(Other definitions for demesne that I've seen before include "Estate; sound like belittle" , "Domain" , "Large landed property" , "Land attached to manor" , "Extensive landed property" .)
