In Switzerland, you must be 18 years old in order to get married. Same-sex couples can also get married. People wishing to get married must contact the cantonal registry office (Zivilstandsamt) in Glarus. The registry office will then initiate the marriage preparation procedure. This involves examining whether the requirements for marriage are met. After the procedure has been completed, the wedding must take place within three months. The registry office offers more detailed information on the procedure and the necessary documents. If one person still lives abroad, it is possible to file a request for entry so that he or she can take part in the marriage preparation procedure. If there is a suspicion of a marriage of convenience (Scheinehe), the registry office can deny the marriage. A marriage in the past can also be declared in valid in this case or the residence permit may be withdrawn.
