What is one way to terminate a joint tenancy?

To terminate a joint tenancy, one effective method is through the conveyance of a joint tenant's interest. When a joint tenant decides to transfer their share of the property to another party, this action can fundamentally change the nature of the ownership. In a joint tenancy, all tenants have equal rights to the property, and a key feature is the right of survivorship, meaning that upon the death of one tenant, their share automatically passes to the surviving tenants. However, once a joint tenant conveys their interest to another person, they sever the joint tenancy. This often results in the creation of a tenancy in common between the original joint tenants and the new owner because the new party is not a joint tenant and does not have the right of survivorship.

The other choices do not directly cause the termination of a joint tenancy. While the death of all tenants would indeed end the joint tenancy, it is not a practical or immediate method to terminate it. Mutual agreement can lead to the dissolution of a joint tenancy, but it requires the consent of all parties, making it less straightforward. The purchase of an additional unit does not impact the existing joint tenancy and therefore does not contribute to its termination.
