Which of the following refers to the situation when a joint tenant decides to sell their property?

When a joint tenant decides to sell their property, the share they sell changes to tenancy in common. This is due to the principle of joint tenancy, where all joint tenants hold equal interest in the property with rights of survivorship. If one joint tenant sells their interest, that person’s share does not carry the right of survivorship associated with joint tenancy; instead, it creates a tenancy in common for the buyer. In this arrangement, the new buyer takes ownership as a tenant in common with the remaining joint tenants, who still hold their shares in joint tenancy with each other.

The other options describe scenarios inconsistent with how property interests work in joint tenancy. For instance, the share sold cannot remain under joint tenancy since the essence of joint tenancy is that all parties must hold the property together. Moreover, properties in a joint tenancy cannot simply be designated as unsellable or must be divided equally, as these conditions ignore the rights and actions of individual joint tenants.
