I just need to ask about legal matters. It is about my marriage. I got married 2008 but before the marriage my wife and I is already living together for more than 3 years and we have 1 child aged 2 years old before the wedding on 2008. When we got married there was a problem of the marriage contract up until now. I have 2 first names and in the certificate it has only 1 name. we got married with the help of a religious group but the papers for the marriage were processed through a tribal way. We're not part of any tribe and no seminars happened. We just signed the papers. The marriage certificate is now recorded in NSO. I have a copy already. 6 years after the wedding my wife confessed that he got involved in a relationship with a married man during the time that we're living together with our son that aged 2 years old that time. I just recently knew it. Would be the marriage considered as invalid because of the way and the processed of the wedding. How about what my wife hid from me? would that be a ground for an invalid marriage? Please help I'm in deep confusion right now. I'll be waiting for your response as soon as possible.
