[ULPIANUS libro trigensimo sexto ad Sabinum. ] §2.14.49.prSi quis crediderit pecuniam et pactus sit ut, quatenus facere possit debitor, eatenus agat: an pactum ualeat? et magis est hoc pactum ualere.
[ULPIANUS, On Sabinus, book 36] If someone lends money and agrees that he will sue only to the extent that the debtor is able to perform: is the agreement valid? And the better opinion is that this agreement is valid.
nec enim improbum est, si quis hactenus desideret conueniri, quatenus facultates patiuntur.
For it is not improper if someone desires to be sued only to the extent that his means allow.
