ELI5: Explain Like I'm 5

Bona fide purchaser

Okay kiddo, so let’s say I want to buy this chocolate cake from the store. The person who made the cake sold it to the store, but then the store sold it to me. Now, if there was something wrong with the cake that the person who sold it to the store didn’t tell them, I might get really sick from eating it.

But if I’m a bona fide purchaser, that means I bought the cake in good faith, meaning I didn't know there was anything wrong with it and I bought it from a place that had the right to sell it. So if there was something wrong with it that no one knew about, I wouldn't be responsible for it because I bought it in good faith. It's kind of like when you buy something from a store and they guarantee it, they're saying that you're protected because you're buying from them in good faith.
