The Swedish government doesn't check that the registered address is correct, and if someone you don't know chooses to register at your address then you won't know about it, and even if you did there's no way for you to get rid of that registration. There has been cases of police breaking down doors and rushing in to apartments just because some criminal had registered himself on that address, even though the people who lived there had never heard of that person.

The Internet is not only bad — it is now possible to sign up for notifications when somebody registers at your address (it’s on the Skatteverket web, somewhere). However, Sweden being Sweden, I suppose you will still have to prove that they do not in fact live there to get rid of them...

Made me think of the opposite problem - in Spain you have to prove that the people who live in your house shouldn't, really. It can take years to evict squatters.

It's partly a different issue.

In the first one, you have someone registered at your house despite not living there. Getting notified about it doesn't solve it though. You still have to report it as a crime and then they will investigate before fixing it. Due to all the bombings, they implemented a speed track a few years ago when gang members are involved (so they don't blow up your house during the process) but I still believe it takes months to solve.

In your case, you have physical squatters. Then you need to take it to court and prove that they shouldn't have access to your house. It takes many months to sort out and they can claim that they have an agreement with you. This was major news in Sweden about 5-8 years ago when waves of EU beggars were making camps on people's land that cost a ton of money to clean up afterwards.
