I'm pretty sure the Commonwealth of Virginia specifically does not recognize "joint tenants with right of survivorship", or "tenants in common" for unmarried persons. I'll have to check on that. Virginia law is astoundingly oppressive in such matters.

The Virginia legislature, in the first drafts of this bill, specified "same-sex couples," but quickly realized the legal issues they would run into... so they got around it by amending it to specify "unmarried persons." On the surface, that would seem less discriminatory... except that, if they really want the legal protections, heterosexual couples do have an option. They can get married. Regardless of how much I want those same protections, I am expressly forbidden by law to qualify myself for them.
