[ULPIANUS libro quarto ad Sabinum. ] §45.3.2.prSeruus communis ipse sibi stipulari non potest, quamuis constaret eum se stipulari domino posse: non enim se domino adquirit, sed de se obligationem.
[ULPIANUS, in the fourth book on Sabinus.] A common slave cannot stipulate for himself, although it is established that he can stipulate for his master that he himself be given; for he does not acquire himself for his master, but rather an obligation concerning himself.
