 In a "sine manu" marriage, the wife remained under the legal control of her father.In both "cum manu" and "sine manu" marriages, if both the husband and wife were "alieni iuris" (persons under "patria potestas"; that is, under the power of their respective "patres familias"), the marriage could only take place with the approval of both "patres familias".Procedures for initiating and terminating marriage varied with the type of union.
