It’s like, “Your papers, please,” but for things you own.

Authorities in Britain have begun trying out a new police power called unexplained wealth orders under a law that took effect last year. The police go to a court and say you’re living way above any known legitimate income. The judge then signs an order compelling you to show that your possessions (whether a house, fancy car, or jewelry) have been obtained honestly and not with dirty money. In the meantime, the boat or artwork or other assets get frozen, and you can’t sell them until you’ve shown you obtained them innocently.
