A form of concurrent ownership of property between two or more persons, in which each has an undivided interest in the whole property. Each co-tenant is entitled to the undivided possession of the property, according to his proportionate share and subject to the rights of possession of the other tenants. Their interests may be equal (as in joint tenancy) or unequal. Where the conveyance document does not specify the extent of interest of each co-tenant, there is a presumption that the shares are equal. There is no rights of survivorship. Any tenant in common can sell his interest in the property without the consent of his co-tenants.
