My cousin was in love with a girl since he was in college. Since they both belong to different caste, neither of their parents accepted. His parents fixed his marriage with a different girl in March 2011. My cousin was not willing for this, but his parents fixed. Meanwhile he and his girlfriend got married through Arya samaaj in Feb 2011. They didn’t tell us that they got married. They have informed the bride that they already got married. They have sent some photos of their marriage to her through e-mail. She was in confusion and didn't inform everyone. My uncle and aunty were very stubborn in conducting the marriage. Unfortunately his second marriage also happened. He is living with his second wife. As a proof of first marriage they have the marriage certificate from Arya samaaj. His second marriage is legally registered. Could you please let me know which marriage is legally valid? Thanks in advance.
