Owing money their end, abroad (2,3,3)
I believe the answer is:
in the red
'owing money' is the definition.
(I've seen this before)
'their end abroad' is the wordplay.
'abroad' indicates anagramming the letters.
'their'+'end'='theirend'
'theirend' with letters rearranged gives 'IN THE RED'.
(Other definitions for in the red that I've seen before include "OD - with 23 & part of 13a" , "needing cash injection" , "Broke" , "Flashing lamp" , "have no credit" .)
