One requirement is to do a "Fürbitte" aka a prayer for the fugger so he can get forgiveness and remain in heaven/ leave purgatory. At least that is what i ve heard.
> Original residents of the Fuggerei were asked to offer three prayers a day for Jakob Fugger and his family. …
> "Jakob Fugger says they have to pray for him. Our administrator always says he is in heaven and will see if you do that. You are responsible for that," said Herzog.
> In other words: that part of the deal is between residents and God.
