My friend had married a girl last year without telling anyone from his and her family. So after wedding she was living with her parents. The wedding was performed with buddhist rituals. Later he had planned for marriage registration. Girl due to pressure from her family or some unknown reason did not agree on signing the marriage registration papers. This caused a lot of quarrels between them and they decided to break their relationship and they did not talk to each other after that. They however did not do anything to legally end this relationship. No one from either family knows anything about it.
My friend is now planning to get married with another girl selected by his family. My concern is what trouble can first girl give to him legally if she decided to make his life miserable. What all IPC laws can he be subjected to if he goes ahead with this second marriage? What is best leagal way out of this problem for him.
