Divisive bit of info on debtor’s documents (8)
I believe the answer is:
factious
'divisive' is the definition.
(synonyms)
'bit of info on debtor's documents' is the wordplay.
'bit of info on debtor' becomes 'fact' (I can't justify this - if you can you should give a lot more credence to this answer).
'documents' becomes 'IOUs' (IOU is an example).
'fact'+'ious'='FACTIOUS'
Can you help me to learn more?
(Other definitions for factious that I've seen before include "Quarrelsome" , "Seditious, divisive" , "Characterised by internal strife" , "Ready to quarrel" .)
