A live-in relationship, also known as cohabitation, refers to an arrangement in which an unmarried couple lives together in a long-term committed relationship, often without being legally married. It is a consensual union between two adults who are in a relationship and decide to live together in the same household.
Thus, living with a woman in a live-in relationship does not constitute offence. If after solemnization of marriage your husband lives in a live-in relationship in the nature of marriage then it constitutes an offence.
Therefore, at this stage you have the right to break the agreement of marriage and claim compensation from the opposite party. Concealment of fact regarding the live-in relationship constitutes a valid ground for the cancellation of marriage.
Since your fiancé concealed this important fact from you, he is liable for the damages caused to your reputation and the mental distress you have experienced. It may not be advisable to file a criminal case for cheating, as there is a possibility that he may end his relationship and remain faithful to you after the marriage.
