OSNepalNews, Kathmandu, 13th Dec: Marriage is defined differently, and by different entities, based on cultural, religious, and personal factors. A commonly accepted and encompassing definition of marriage is the following: a formal union and social and legal contract between two individuals that unites their lives legally, economically, and emotionally. The contractual marriage agreement usually implies that the couple has legal obligations to each other throughout their lives or until they decide to divorce.
