Donatio Propter Nuptias
As a rule, mutual gifts between husband and wife were void. But gifts made before marriage by a man to his betrothed was valid. Such a gift was called a doitatio ante nuptias. This term, however, in time acquired a special technical sense and denoted a gift made before marriage by the prospective husband, or by some one on his behalf, to the future wife for her support, it being deemed important that married women should have property of their own, so that they might not be unprovided for in the event of the dissolution of the marriage.
The object of the' donatio ante nuptias was to make such provision. Originally the donation had to be made before marriage, but by Justinian's legislation it might be made after marriage, and its name was changed to donatio propter nuptias. Upon the dissolution of the marriage, both dos and donatio propter nuptias belonged to the wife, the former being the property derived from her own side and the latter that derived from her husband's side.
It was common for the gift by the husband to be returned to him in the shape of dos. And sometimes, also, the donatio was not actually paid but merely covenanted for at the time of the marriage, and could be recovered by the wife upon its dissolution. The property given as dos and donatio propter nuptias belonged to the wife alone and the children of the marriage had no interest therein.
