Prior to being married in Alberta, you must obtain an Alberta Marriage License from an Alberta Registry office. Fees vary between Registry Offices. This license is valid for 3 months from the date of issue. The Registry office will prepare a marriage license and a Registration of Marriage that must be presented to the Marriage Commissioner prior to the wedding. Within the civil ceremony there are mandatory phrases that must be stated. Other aspects of the civil ceremony can be customized to meet your wishes. At the wedding, the Registration of Marriage is signed by the bride, groom, two witnesses and the Marriage Commissioner. The Marriage Commissioner will complete the paperwork and process it with the Vital Statistics office. A  Statement of Marriage, prepared by the Marriage Commissioner, will be presented to you at the completion of the ceremony.
