Only married couples can own property as tenants by the entirety so what happens if an unmarried couple buys property with a deed that purports to convey a tenancy by the entirety interest? If we presume that the goal was to create a right of survivorship, then we should interpret it as a joint tenancy. If we adopt the general presumption in favor of tenancy in common for ambiguous conveyances, then it should be a tenancy in common.
The D.C. Court of Appeals adopted the former assumption and interpreted a conveyance to a father and a son as a joint tenancy finding the entireties language sufficient to overcome the statutory preference for tenancies in common. In re Estate of Hamilton, 299 A.3d 542 (D.C. 2023).
