Interestingly, about 10% of land in England and Wales still isn't actually registered with the land registry. Mainly because registration only became compulsory fully in 1990 and still only when the land was sold or mortgaged.
In Scotland only ~58% of land is in the registry - most of the rest is covered by a register of transactions but that can make it difficult to work out who owns what.
> Land ownership is quite a contentious issue in Scotland.
Yes, I saw an article recently that said that approx 50% of Scottish Land is owned by just 420 families. It's actually worse than England in that respect.
