The establishment of joint tenancy' ownership of property, or the termination of such a tenancy, may have federal gift tax consequences to the co-owners of the property. Consequently, the gift tax is a factor to be weighed before embarking on either of these ventures. The gift tax consequences are determined by the nature of the property rights enjoyed by the joint tenants under the controlling state property law, and accordingly it is desirable, where Michigan property law is applicable, to consider the Michigan law and the significance of that law to the operation of the gift tax. However, before discussing Michigan property law, it may be helpful to review briefly the general principles controlling the applicability of federal gift taxes to joint tenancy interests.2
