Question on In-game Petitions

[SmartBud14]

I realize that in-game petitions probably take a while, but does anyone know how I will know when my in-game petition is answered? I am waiting on a corpse summon and petitioned days ago. I'm just not sure if the corpse will be summoned to a specific spot that I should be checking, or if I will receive some kind of in-game response letting me know what was done. Any helpful responses are greatly appreciated. Thanks.
