[ULPIANUS libro primo responsorum. ] §45.2.8.prHis uerbis: 'eaque praestari stipulanti tibi spopondimus' interesse, quid inter contrahentes actum sit: nam si duo rei facti sint, eum qui absens fuit non teneri, praesentem autem in solidum esse obligatum, aut si minus, in partem fore obstrictum.
[ULPIANUS in the first book of Responses.] With these words: 'eaque praestari stipulanti tibi spopondimus' (and we have promised to you, the stipulator, that those things shall be performed), it makes a difference what was done between the contracting parties: for if they were made two joint debtors, he who was absent is not bound, but the one present is bound for the whole, or if not, he will be bound for a part.
