Owners of apartments in a German building meet at least once a year to decide on repairs, costs and rules. The invitation should reach them at least three weeks before the meeting, unless the matter is especially urgent. Under the Condominium Act, a resolution is valid only if its subject was named in the invitation. A typical agenda item therefore reads Beschluss über die Sanierung der Fassade, resolution on the renovation of the facade, not a vague heading such as Allgemeine Überlegungen, general considerations.
