Polygamy is very rare among the Banias, and it is generally the rule
that a man must obtain the consent of his first wife before taking
a second one. In the absence of this precaution for her happiness,
parents will refuse to give him their daughter. The remarriage of
widows is nominally prohibited, but frequently occurs, and remarried
widows are relegated to the inferior social groups in each subcaste as
already described. Divorce is also said to be prohibited, but it is
probable that women put away for adultery are allowed to take refuge
in such groups instead of being finally expelled.
