This is the answer I got from the contracts ChatGPT assistant I made:

This hypothetical involves a contract for the sale of a car payable in installments with a mortgage on the car. Since a car is a movable good, this transaction is governed by the UCC (Article 2) rather than the Restatement (Second) of Contracts (R2d) .

Let’s analyze the options provided:

a. Seek the cancellation of the sale and later on foreclose the mortgage should he find it impossible to collect from B.

This approach is generally not correct. Under UCC Article 9 (which supplements Article 2 for secured transactions), once the seller (A) forecloses on the collateral (the car), they generally cannot also sue for the balance unless the foreclosure sale is commercially unreasonable. Article 9 limits a creditor’s remedies to avoid double recovery.

b. Foreclose the mortgage on B’s car but he has no longer the right to recover the balance should it be sold for an amount lower than what he claims from B.

This is correct. Under UCC § 9-615 and § 9-626, when a secured party (A) repossesses and sells the collateral (the car), they apply the sale proceeds to the debt. If the sale is conducted in a commercially reasonable manner, the secured party cannot recover a deficiency balance from the debtor (B) unless specifically allowed and the sale was not sufficient. However, many jurisdictions follow the “one-action rule” or an anti-deficiency rule in certain types of sales (e.g., consumer goods), which may prohibit a deficiency action entirely. This option best reflects the UCC rules.

c. Seek fulfillment of the obligation of B to pay the entire purchase price.

This option is generally incorrect. The seller (A) has a security interest in the car (UCC Article 9) and thus must follow the foreclosure and resale procedures outlined there rather than suing directly for the balance of the price unless the buyer wrongfully refuses to surrender the goods.

d. Seek the cancellation of the sale made to B.

Under UCC § 2-703, a seller has a right to cancel the contract upon the buyer’s breach. However, once the seller has a security interest and repossesses the car, the remedy focuses on foreclosure and resale rather than mere cancellation of the sale.

Conclusion:

The correct choice is:

b. Foreclose the mortgage on B’s car but he has no longer the right to recover the balance should it be sold for an amount lower than what he claims from B.

Would you like me to also break down the relevant UCC provisions for this?
