Under what condition can a joint tenancy be destroyed?

A joint tenancy can be destroyed when any one of the four essential elements of joint tenancy is terminated. These elements include unity of possession, unity of interest, unity of time, and unity of title. If any of these elements is lost, the joint tenancy ceases to exist, resulting in a change in ownership structure, typically converting it into a tenancy in common.

For instance, if one joint tenant sells their interest to another, it disrupts the unity of title, which can dissolve the joint tenancy. Similarly, if one party passes away, affecting the joint tenancy's survivorship aspect, that element is also terminated.

Other conditions, such as bankruptcy, primarily impact an individual's financial status and obligations, but they don't directly affect the ownership structure of the property unless one of the aforementioned unity requirements is compromised. Selling the property, while it does involve a transaction, wouldn't necessarily destroy a joint tenancy either, unless it impacts the aforementioned unities that define that type of ownership.
