Introduction:
In a contract for the sale of goods, it is important to determine when the property in the goods passes from the seller to the buyer. This is significant because it affects the rights and obligations of both parties in relation to the goods. There are different forms of contracts that can be used for the sale of goods, and each form determines when the property in the goods passes to the buyer. One such form is the installment to sell contract.

Explanation:
An installment to sell contract is a type of contract where the buyer agrees to purchase goods in installments, with the property in the goods passing to the buyer immediately upon delivery of each installment. This means that the buyer becomes the owner of each installment of goods as soon as they are delivered.

Key Points:
- Passes of property: In an installment to sell contract, the property in the goods passes to the buyer immediately upon delivery of each installment.
- Ownership: This means that the buyer becomes the owner of each installment of goods as soon as they are delivered.
- Installment basis: The goods are sold and delivered in installments, and the buyer's ownership is established for each installment separately.
- Rights and obligations: Once the property in the goods passes to the buyer, they are responsible for any loss or damage to the goods.
- Payment: The buyer is also obligated to make payment for each installment as per the terms of the contract.

Conclusion:
In an installment to sell contract, the property in the goods passes to the buyer immediately upon delivery of each installment. This form of contract allows the buyer to become the owner of the goods as soon as they are delivered, and they are responsible for any loss or damage to the goods. It is important for both parties to clearly understand the terms and conditions of the contract before entering into such an agreement.
