Quote from Lily in We're Not From Here
Lily: Yeah. You're writing constantly. There's forms we have to sign, our death folders, thank you notes... Barney: Whoa. Whoa. What are death folders? Lily: It's this thing they recommend you do in case one spouse died unexpectedly. Marshall: It's all the information your spouse might need all in one convenient location. Lily: Yeah. Account info, important addresses, a letter to the other person, all that stuff. I'll get the next round. Marshall: I am such a jerk. Barney: Yeah. Wait, why? Marshall: I didn't know that I was supposed to write a letter. All Lily's gonna find in that folder are a bunch of bank statements and a funny list of things to do with my ashes. Ted: Marshall brownies. Marshall: Number six.
