A more thorough explanation:

An agreement of sale is a legal document that outlines the terms and conditions of a sale between a buyer and a seller. It is a contract that sets out the details of the transaction, including the price, payment terms, and any other relevant information.

John wants to buy a car from Jane. They agree on a price of $10,000 and John agrees to pay in three installments over the next three months. They sign an agreement of sale that outlines these terms and any other relevant details, such as the make and model of the car and the date of the sale.

Another example could be a real estate transaction. A buyer and seller agree on a price for a house and sign an agreement of sale that outlines the terms of the transaction, such as the closing date and any contingencies.

These examples illustrate how an agreement of sale is a legally binding contract that sets out the terms and conditions of a sale between a buyer and a seller.
