Joint tenancy is a form of property ownership that often factors into estate planning. If two people own a piece of real estate, for example, they can either be joint tenants or tenants in common. Under the latter, a tenancy in common, each person separately owns his or her share of the property. Thus, when one co-owner dies, his share passes through his estate like any other property. But under a joint tenancy, when a co-owner dies, his or her share simply ceases to exist; the surviving co-owner (or co-owners) acquire full title immediately upon the deceased co-owner’s death. Nothing passes through a will, trust or probate process.
A joint tenancy requires four conditions, known as the “four unities”: (1) the co-owners acquire the property at the same time; (2) the co-owners share identical same title to the property; (3) each co-owner has an identical share of the property; and (4) the co-owners have an equal right to possess the property. If any of these conditions are not met, or cease to exist, there is no longer a joint tenancy, but a tenancy in common.
Recently, the California Court of Appeals addressed a dispute over a joint tenancy that was dissolved shortly before one of the co-tenants died. The surviving co-tenant argued the joint tenancy remained in force. The probate court and the Court of Appeals disagreed. The case is discussed here for informational purposes only.
