@68colliam: Joint tenancy: Whatever the number, these co-owners have no shares in the property, say land. They all own the whole property as if it was for one person. They could be related by blood or just business partners. The ownership is the same. It has two characteristics, namely, survivorship and the 4 units. Read "Burton v Camden (2000)" to understand in details. Be law smart. Follow me for more of such.
