Which of the following arrangements would typically not allow heirs to inherit the property upon a co-owner's death?

In examining the arrangements for property ownership, it's important to understand how each form impacts inheritance rights. Joint tenancy is characterized by the right of survivorship, which means that when one co-owner of the property dies, their interest automatically passes to the surviving co-owner(s) rather than going to their heirs. This feature is pivotal in distinguishing joint tenancy from other forms of ownership.

In contrast, tenancy in common allows each co-owner to pass on their share of the property to their heirs upon death. Similarly, tenancy by the entirety, which is a form of joint ownership specifically for married couples, also features the right of survivorship. Severalty ownership, held by a single individual, does not involve co-owners and naturally allows the owner to leave the property to their heirs.

Therefore, joint tenancy is the arrangement that typically does not permit heirs to inherit the property when one of the co-owners dies, as the surviving co-owner automatically takes full ownership. This principle reflects the fundamental legal implications of joint tenancy regarding succession and inheritance.
