POST MATRIMONIAL INVESTIGATION -- Post matrimonial investigation is a check on spouse’ activities like infidelity, cheating, etc. Mostly the need for such investigation arises, if marriage is initially done without pre-matrimonial investigation. The marital disloyalty basically arises due to the suspected cheating activities of the life partner. If such cheating by one spouse on the other is knowingly continued, it turns the marriage upside down and ends with the legal dissolution of the marriage. As far as any previous relationship is concerned; it may not be taken into consideration, if it is a thing of the past. What is more important is to be faithful to each other after marriage. Mismatch results in extra-marital relationship and spouse infidelity which totally shatters the married life. To unearth any such possibility of breaking of marital vows, it would be better to seek the guidance of a private detective.
