20 Pa.C.S. § 6402

Only individuals whose registration of a security shows sole ownership by one individual or multiple ownership by two or more 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.
