JTWROS is titling a deed as joint tenants w/ rights of survivorship - which is how I hold title w/ my adult son so that when the time comes the DVC contracts will be 100% his w/out having to mess w/ and pay for probate in Florida & he can sell or keep them.
Married couples can hold title as tenants by the entireties which also avoids Florida probate. In looking at the OC controller site it looks like DVC typically grants deeds to John Doe & Jane Doe, husband and wife, to create tenants by the entireties.
I’m not an expert in Florida real property law but this site explains the options available.
