Final answer:
The seller and buyer have an insurable interest in property during transit for Inland Transportation Insurance because both parties potentially bear the risk of loss or damage to the goods depending on the terms of their agreement.
Step-by-step explanation:
The two parties who may have an insurable interest in property while it is in the course of transit for Inland Transportation Insurance are the seller and the buyer. This is because the seller retains the risk of loss or damage to the goods until they are delivered to the buyer, unless otherwise agreed upon in their contract.
The buyer, on the other hand, has an insurable interest in the goods once they take ownership or when the goods are being shipped to them, depending on the terms of the sale contract (such as FOB Shipping Point or FOB Destination). Therefore, both parties have a financial stake in the goods during transit and may seek to protect that interest through insurance.
