Adverse possession hasn't been a thing people can claim for many years now
Actually, you're wrong about that.
If the land is unregistered (and there is still a lot of unregistered land) then after 12 years you can make a claim for adverse possession.
If the land is registered then the process is a bit more complicated.
First of all, you need to wait for 10 years. You then make an application to the Land Registry and they will contact the registered owners and let them know that you are making an application for adverse possession.
The registered owner then has 65 working days (so, about 3 months) in which to object to your application.
If they don't object in time then, great, the land's yours.
If they do object then your application is rejected, but that's not quite the end of things.
The owner then has two years in which to start proceedings against you in court to get off their land.
So, if you either agree to vacate the land or they start court proceedings against you within two years then you're probably not going to get the land (although there are circumstances where you still could get the land).
However, if at the end of those two years the owner hasn't started court proceedings then you're free to make another application and this time it can't be refused.
Although, please note that if the land belongs to the Crown or government departments etc then the time is actually 30 years.
