contrary to what some people may believe, the term joint tenant with the right of survivorship has nothing to do with being a lessee or tenant in a rental apartment. a jtwros is one version of co-tenancy that gives co-owners equal rights to the asset in addition to the right of survivorship. a joint tenant with right of survivorship differs from a tenancy in common. while parties in a jtwros must have an equal stake in the asset or property, tenants in common aren’t bound by this rule.
