Sorry to be a pain, I hope this is the correct forum too.
I bought some shares for a company in the uk and now I would like to sell them. I have lost my certificate of purchase of these shares. What can I do now?
This is not a disaster. The registrar is usually a professional service and well used to this kind of stuff. Find out who they are from web site, or the company secretary, and they will have procedures to sort this out fairly easily for you
