LEGAL REQUIREMENTS FOR SCOTTISH WEDDINGS
Scotland does not have a residency law for couples who would like to marry here, which means that as long as all of your legal documents are in order you can be married in Scotland fairly soon after you arrive in the country.
If you would like a religious ceremony, you are not limited to a church wedding. As long as you have agreement from a minister, a religious ceremony can be performed in any location for which either an address or a grid reference is available. Alternatively, a registrar can perform a civil ceremony, or you can opt for a humanist ceremony. In all cases, the bridal couple along with their two witnesses and the celebrant sign the Marriage Schedule. This document is legal anywhere in the world.
