With its profound meaning, marriage is one of the oldest social constructs, predating the formation of the state and even the law. Despite its growing importance, states have not defined marriage within the framework of fundamental law. As a result, the legal aspects of marriage have undergone significant changes, and it is only recently that marriage has come under the jurisdiction of the state. As a rule, marriage and related issues are part of civil legislation; they may be provided for in both the Unified Civil Code and the Special Family Code. The article discusses the Georgian experience with the constitutionalisation of marriage and the evolution of the constitutional regulation of marriage in the Democratic Republic of Georgia.
