[GAIUS libro uicensimo octauo ad edictum prouinciale. ] §18.1.53.prUt res emptoris fiat, nihil interest, utrum solutum sit pretium an eo nomine fideiussor datus sit.
[GAIUS, On the Provincial Edict, Book XXVIII] In order for the property to become the buyer's, it makes no difference whether the price has been paid or a guarantor has been provided on that account.
quod autem de fideiussore diximus, plenius acceptum est, qualibet ratione si uenditori de pretio satisfactum est, ueluti expromissore aut pignore dato, proinde sit, ac si pretium solutum esset.
Moreover, what we have said about a guarantor is accepted more broadly: if the seller is satisfied in respect of the price by any means whatsoever, as for example by providing a substitute debtor or a pledge, it is to be treated just as if the price had been paid.
