I was asking for facts, not gut feelings. Can you name any kind of certificate or any other kind of paper a immigrant could get now which would help him in the future?
Isn't that the whole point of the original article, there will be a cutoff point, people assumed it would be when we left the EU but the government is about to state that it will be when we call article 50.
A marriage certificate?
Why would you have to immigrate _now_ for a marriage certificate? Do you think the situation will worsen even more for couples married after the cut off date?
