Is sued, perhaps, for neglect (6)
I believe the answer is:
disuse
'for neglect' is the definition.
(both can mean a state of disrepair)
'is sued perhaps' is the wordplay.
'perhaps' indicates an anagram.
'is'+'sued'='issued'
'issued' anagrammed gives 'DISUSE'.
(Other definitions for disuse that I've seen before include "State of not being employed" , "Fall into this state to be unemplyed? (6)." , "Neglect; abandonment" , "Issued (anag)" , "Neglect; desuetude" .)
