This discussion addresses the illegal conversion of common passages or courtyards into car parking spaces within apartment complexes. It clarifies that 'demurrage' is not the correct term for this situation, as demurrage relates to shipping delays. Instead, the focus should be on illegal encroachment and property law. Owners affected by such conversions are advised to formally notify the encroaching parties and consult a property law specialist for legal guidance and to explore remedies, which may include complaints to local authorities.
