What co-ownership allows for equal interest and the right of survivorship?

The concept of co-ownership that allows for equal interest and the right of survivorship is Joint Tenancy. In a joint tenancy arrangement, each co-owner holds an equal share of the property, and importantly, if one of the co-owners passes away, their share automatically transfers to the remaining co-owners. This is known as the right of survivorship, which differentiates joint tenancy from other forms of ownership such as tenancy in common, where there is no automatic transfer of ownership upon a co-owner's death.

Additionally, community property refers to property acquired during marriage and is owned equally by both spouses, but it does not provide the right of survivorship. Partnerships involve co-ownership in a business context rather than real property, which also does not pertain to the question. Thus, Joint Tenancy is the correct answer as it encapsulates both equal interest and the vital element of survivorship, establishing the automatic passage of ownership rights amongst co-owners.
