This discussion clarifies the sale of shares in an unregistered property based on a family settlement MoU. While an individual can sell their 25% share to a willing buyer without explicit consent from other shareholders, possession cannot be handed over until the property is legally partitioned. An unregistered MoU is generally invalid for immovable property, so a registered Partition Deed is essential. Once partitioned, each share becomes self-acquired property, allowing the owner to sell it freely.
