Yes. You are required to submit your marriage certificate to the court with your application for a divorce. The marriage certificate also contains information that is needed to draft the divorce application. In most cases the marriage certificate is scanned in to be sent electronically through the digital application process. The scanned copy must be of the original marriage certificate or a formal certified copy. If you have lost your certificate or you do not have it in your possession, then you can apply for a further copy for a small fee at the General Register Office or sometimes the venue where the marriage took place. If you are required to send a hard copy of the marriage certificate be aware that the court will retain it although it may be possible to apply specifically for its return at a later date.
