umm why don’t you brush up on your definition regarding ‘joint tenancy’?
Joint tenancy is when you have equal share in the property but if your spouse/or your joint tenant passes away, you have a right of survivorship and are thus able to own the property in its entirety. Ownership thus passes to the surviving spouse immediately, thus avoiding the need for probate.
So I am sorry but YOUR argument falls short (yet again) of making any sense.
