A. When any joint tenant dies, before or after the vesting of the estate, whether the estate is real or personal, or whether partition could have been compelled or not, his part shall descend to his heirs, pass by devise, or go to his personal representative, subject to debts or distribution, as if he had been a tenant in common.
B. This section shall not apply to any estate that joint tenants have as fiduciaries or to any real or personal property transferred to persons in their own right when it manifestly appears from the tenor of the instrument transferring such property or memorializing the existence of a chose in action that it was intended the part of the one dying should then belong to the others. This section does not affect the mode of proceeding on any joint judgment or order in favor of or on any contract with two or more one of whom dies.
