法律問題(業權與股份相同嗎)

Property is governed by the Conveyancing and Property Ordinance. Any changes in the ownership of the property must be registered in the Land Registry by a separate very formal legal document e.g. Assignment Deed etc. The legal document has to be signed by all the owners, you and your family members, of the property.
For change in partners in a partnership firm, you have to make the changes quite common in the Profits Tax Return and with the knowledge and consent of the remaining partners.
So, this is a separate and distinct issue for ownership in property and in a partnership firm. To avoid misunderstanding, you can just clearly state the name of the firm with the BR number instead.
