[ULPIANUS libro sexagesimo tertio ad edictum. ] §23.3.3.prDotis appellatio non refertur ad ea matrimonia, quae consistere non possunt: neque enim dos sine matrimonio esse potest.
[ULPIANUS in the sixty-third book on the Edict.] The term "dowry" does not apply to those marriages which cannot legally exist; for there can be no dowry without marriage.
ubicumque igitur matrimonii nomen non est, nec dos est.
Therefore, wherever the name of marriage does not exist, neither does a dowry.
