Who manages your condominium fees for the building?

Normally (In Portugal, Spain, Germany and at least some developments in Brazil) one of the residents is the "president" (which is either always the same or can vary). The President decides how the condominium charges are spent. Possibly the ones in Brazil don't have much interest in keeping the exterior clean (or they want to keep the condominium charges low) so they spend it elsewhere.

Or maybe the owners of the properties got together and discussed it and decided they wanted to keep the charges to a minimum?
