Possibly in Japanese do not exist therm like this. Even in English it could be
rare. Anyway, how could I translate it in Japanese? The meaning of sub-debtor
should be "debtor of debtor".

Let me give the example sentence (please sorry in case if you will find it
confusing):

" _The pledge of receivables arising from the Respective Receivables created
under the Pledge Agreement shall be considered as validly existing until the
moment the Sub-debtor receives a notice from the Pledge on termination of such
pledge._ "

Translation of the word "sub-debtor"
Debtor is 債務者. Principal debtor is 主たる債務者、 主債務者.

If Sub-debtor is a "non-principal debtor" (a debtor other than the principal
debtor), it could be 副債務者, 副次債務者, etc.

Otherwise, perhaps something like a sub-contractor is meant, and you may have
to make up a plausible term. (Subcontractor is 下請（事）業者、再委託先、再委託業者)
