The Supreme Court of Tennessee overruled prior cases and adopted the Arkansas approach that allows spouses that own bank account as tenants by the entirety are free to withdraw funds unilaterally (without consent of their co-owner) and that moneys so withdraw become the individual property of the spouse that withdrew the funds. This contrasts with real property which neither spouse may convey without the consent of the other. In re Estate of Fletcher, 538 S.W.3d 444 (Tenn. 2017).
It should be noted as well that Tennessee presumes that a conveyance to a married couple is held as a tenancy by the entirety unless the language provides otherwise.
