Recent studies have shown that extrasolar planetary systems are prevalent around main-sequence stars in the Milky Way. However, little is known about their fate towards the end of the stellar evolution. In this talk, I will show various evidence that some white dwarfs are dynamically active and planetary systems could be prevalent around white dwarfs. I will also talk about the recent discovery of an actively disintegrating asteroid around a white dwarf and how this system fits into our overall understanding of the fate of planetary systems.
