In both a tenancy in common, and a joint tenancy, each co-owner owns an undivided interest in the property.

Tenancy in Common

A form of co-ownership where each party owns a separate fraction of the property and can transfer their interest independently.

Joint Tenancy

Joint ownership of property by two or more co-owners in which each co-owner owns an undivided portion of the property. On the death of one of the joint tenants, his or her interest automatically passes to the surviving joint tenant(s).
