Do i need to go for a legal divorce ? I wanted to marry a woman but she is not in the same religion , so i am not concern of the marriage inside church . I will do the marriage registered with the girl who i am going to get married . But legally will there be any complication , like if the other woman comes back one day , will the girl who i am going to get married now will be in trouble or Is there any complication ? 
Question: Why is this person asking about divorce ?
He wants to get married to a different person .
