(1) The unpaid seller may exercise his or her right of stoppage in transitu either by taking actual possession of the goods, or by giving notice of his or her claim to the carrier or other bailee or custodier in whose possession the goods are. Such notice may be given either to the person in actual possession of the goods or to his or her principal. In the latter case the notice, to be effectual, must be given at such time and under such circumstances that the principal, by the exercise of reasonable diligence, may communicate it to his or her servant or agent in time to prevent a delivery to the buyer.
(2) When notice of stoppage in transit is given by the seller to the carrier, or other bailee or custodier in possession of the goods, he or she must re-deliver the goods to, or according to the directions of, the seller. The expenses of such re-delivery must be borne by the seller.
