My ex has asked for a copy of the marriage certificate. I'm pretty confident that when I applied for divorce I gave it to my solicitor and I never saw it again. Is this normal? I have the Decree Absolute and been fully divorced for a year now (thank god!) should I have the marriage certificate, and will I ever need it in the future?
You don't get the marriage certificate back which is why some people get a copy for divorce purposes and keep the original.
Copies of certificates for UK marriages can be easily obtained should you want one. I cannot see why you might as the marriage is over. It is the Decree Absolute you may need in future so keep track of that ?!
