(c) What were the main conditions of the oral agreement between the parties? The principles established by the courts are therefore that any sale is considered a cash payment, unless otherwise provided. If the seller has not granted credit to the buyer or has not accepted a guarantee for payment by the buyer, the sale is made against payment in cash, unless the seller has granted the buyer a significant period of time to pay the purchase price. Whether or not the seller wished to transfer the property can be inferred from the facts. If the seller enters into a contract for the handover of ownership to the buyer in which full payment has not been made or secured, this is a sale on credit and ownership would be transferred with delivery of the goods. . . .
