Person owed money (8)
I believe the answer is:
creditor
'person owed money' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for creditor that I've seen before include "Moneylender" , "He's the one owed the money" , "one to whom money is due" , "The one to whom debt is due" , "to whom something is due" .)
