Does the right of survivorship apply with out a will?

The right of survivorship literally means that a will is not required. That is, between two people (A and B, for example) who are co-tenants with right of survivorship to a piece of property, the one of A and B who is alive after the other's death will own the property in full. So if A dies first, B will own the property outright, and if B dies first, A will own the property outright. So in any case, right of survivorship by its very existence means that a will is not required regarding that particular item of property only.
