I've honestly never had that particular situation arise. The closest I’ve come was when a character got killed and then raised, but then the player had already decided they didn’t want to play that character anymore. So that character retired and the new character jumped into play next session.
Whether they decide to make a new character or the old one is raised, my goal is to get them back into play as quickly as possible. So that if they need to get raised by an NPC, the required quest or payment will occur after the character is up and on their feet again. No one likes just sitting around at the gaming table, doing nothing.
