[MODESTINUS libro secundo differentiarum. ] §42.1.20.prNon tantum dotis nomine maritus in quantum facere possit condemnatur, sed ex aliis quoque contractibus ab uxore iudicio conuentus in quantum facere potest, condemnandus est ex diui Pii constitutione.
[MODESTINUS, in the second book on Differences.] only is a husband condemned to the extent of what he is able to perform on the ground of a dowry, but even when sued in judgment by his wife on the basis of other contracts, he is to be condemned to the extent of what he is able to perform, according to a constitution of the divine Pius.
quod et in persona mulieris aequa lance seruari aequitatis suggerit ratio.
The principle of equity suggests that this should be observed with an equal balance in the person of the wife as well.
