Hindrance or disadvantage (9)
I believe the answer is:
liability
I believe this clue is a double definition.
'hindrance' is the first definition.
(I've seen this before)
'disadvantage' is the second definition.
(thesaurus)
(Other definitions for liability that I've seen before include "Hindrance" , "Debt; drawback" , "Financial obligation" , "Indebtedness" , "duty" .)
