I feel like it's more common than you'd think. I swear I heard that they do this in places like France, too, because wasn't Jim Morrison's grave up for lease again recently?? Okay, not "recent," as this article is from 2000, but https://www.latimes.com/archives/la-xpm-2000-sep-28-mn-28119-story.html. Pere LaChaise agreed to lease his grave in perpetuity, which means that that's unusual??

Funky.

We actually already own a plot for our family in a local cemetery, which is it's own story, but there you go.
