if a married hindu man marries another woman without divorcing his first wife, he could be charged with polygamy. his second marriage is illegal and null and void. but to charge the man with polygamy and penalise him, it needs to be proved that he underwent the necessary rituals that makes a marriage legal under the hindu marriage act. it is here that the dichotomy in the rule complicates matters. the hindu marriage act is governed by the various rituals in various parts of the country, which means that what is relevant in north india does not always apply in the south. the necessary ingredients of a legal marriage under the hma is " datta home " and " saptpadi " (taking seven steps around the sacred fire). but for the reddy community of andhra pradesh these rituals are not necessary. the " saptpadi " is not relevant in a case of bigamy in tamil nadu either. in several judgments (santi deb berma, lingari obulamma and laxmi devi), the supreme court however, said without " saptpadi " a marriage was not complete. so men who committed bigamy, but steered clear ofsaptpadi - were acquitted of bigamy charge. for in order to prove bigamy, it must be proved that the second marriage was performed according to necessary rituals. in tamil nadu, however, such ceremonies as " saptpadi " and " datta home " are not needed for a legal marriage. the state had amended hma and inserted section 7-a for solemnisation of a legal marriage
