Marriage is the ceremony that establishes and recognizes a legal sexual union that will lead to the creation of a family. It is a passport ritual that seals the person's transition from one state to another. The term also denotes not only the conclusion but also the already established legal sexual union. Thus it is an institution, which is defined as the socially recognized union of two persons. Marriage is a vital institution for society - it is no coincidence that unmarried and childless couples have, over time, been more or less marginalized and even today are marginalized or unappreciated in various societies.
