Conn. Gen. Stat. § 45a-468b: Registration in beneficiary form: Sole or joint tenancy ownership.

Only individuals whose registration of a security shows sole ownership by one individual or multiple ownership by two or more individuals with right of survivorship, rather than as tenants in common, may obtain registration in beneficiary form. Multiple owners of a security registered in beneficiary form hold as joint tenants with right of survivorship, as tenants by the entireties, or as owners of community property held in survivorship form and not as tenants in common.
