Able to pay all debts (7)
I believe the answer is:
solvent
'able to pay all debts' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for solvent that I've seen before include "Not in debt" , "Creditworthy" , "Financially viable" , "Having enough money to meet obligations" , "Able to meet liabilities" .)
