What's the main difference between Joint Tenancy & Tenancy in Common?

The Kohab co-ownership model is based on the legal concept of ‘tenants in common’. This basically means that the co-owners hold a share of the whole of the property in common with each other e.g. 50:50. Each owner can transfer their share in the property and pass their shares of the property to their beneficiaries should they die. In the joint tenants’ scenario the share in the property automatically passes to the other co-owner, when they die.
