How sniper disputed possession (9)

I believe the answer is:
ownership
'possession' is the definition.
(ownership is a kind of possession)
'how sniper disputed' is the wordplay.
'disputed' indicates an anagram.
'how'+'sniper'='howsniper'
'howsniper' with letters rearranged gives 'OWNERSHIP'.
(Other definitions for ownership that I've seen before include "The right of possessing something" , "Proprietary right of possession" , "Proprietorship, possession" , "Legal title" .)
