(1) Unless otherwise provided in writing by each settlor who transfers property to a qualified spousal trust, property that is held at any time in a qualified spousal trust, without regard to how the property was titled before the property was held: 
(A) Has the same immunity from the claim of a separate creditor of either settlor as if the property were held outside the qualified spousal trust by both settlors as tenants by the entirety; and
