Looking for a unique memento of your wedding day? Order a Commemorative Marriage Certificate package from the NSW Registry of Births Deaths & Marriages.  Display it in a frame as a keepsake or as part of your album as an everlasting memory. All packages include a standard Marriage Certificate and are essential if you want to change your name after marriage. Commemorative Certificates do not contain security features and organisations may not accept them as a proof of identity document. To apply for your certificate, speak to your celebrant, visit our website or call the Registry.
