Restraints on Divorce
Divorces were very unusual during the Republican period, though practically unrestrained by law. It is said that for five hundred yeai's no one divorced his wife. But under the Empire divorces became extremely frequent, and several laws were enacted plac- ing restraints upon the right of divorce. These laws Ijrohibited divorces except for certain causes, and provided that persons divorcing their spouses without statutory grounds should suffer certain penalties.
Thus a wife illegally divorcing her husband forfeited her dos, and a husband putting away his wife without statutory cause was required to pay her the donatio propter niiptias which he had merely agreed to pay.
Indeed, the primary purpose of the donation (which was an institution of the later Empire) was to secure to a wife divorced without good cause a contribution of property from her husband.
It should be noted that these laws merely prescribed certain penalties for dissolving marriages without any statutory ground. They did not declare divorces without such ground void. A husband or wife was just as free to divorce his or her consort without cause as before. The only effect of the legislation was to require a person dissolving a marriage without statutory ground to pay a penalty for the privilege.
