One owed money (8)
I believe the answer is:
creditor
'one owed money' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for creditor that I've seen before include "He should be paid" , "Lender" , "he advances to you" , "The one to whom debt is due" , "He's the one owed the money" .)
