A homeowner is in dispute over maintenance charges for their larger flat in a joint venture property. While they believe charges should be divided equally among the 8 flats, one owner is demanding double payment based on square footage. The homeowner is seeking legal advice on how to resolve this, as they cannot afford the increased cost and believe the charges should be split evenly, regardless of flat size. The general consensus suggests common charges are typically apportioned equally, and without a registered society, refusing unreasonable demands might be an option.
