1) Each tenant has an unrestricted right of access to the property. Where one co-tenant wrongfully excludes another from making use of the property, the excluded co-tenent can bring a cause of action for ouster, and may receive the fair rental value of the property for the time that he was dispossessed.

2) Each tenant has a right to an accounting of profits made from the property. If the property generates income such as rent, each tenant is entitled to a proportion of that income.

3) Each tenant has a right of contribution for the costs of owning the property. Co-tenants can be forced to contribute to the payment of expenses such as repairs, property taxes, and mortgages on the entire property.

Co-tenants do not have any obligation to contribute to any costs of improving the property. If one co-tenant adds a feature that enhances the value of the property, that co-tenant has no right to demand that any others share the cost of adding that feature - even if other co-tenants reap greater profits from the property because of it.

Furthermore, each co-tenant can independently encumber their own share in the property by taking out a mortgage on that share; other co-tenants have no obligation to help pay a mortgage that only runs to another tenant's share of the property, and the mortgagee can only foreclose on that share.

Finally, co-tenants owe one another a duty of fair dealing. Because of this, any co-tenant who acquires a mortgage claim against the property must give his co-tenants a reasonable opportunity to purchase proportionate shares in that claim.
