The Real Estate Purchase Agreement states that the refrigerator is to go to Jack, the buyer. How should Jack be able to show he owns the refrigerator?

A Bill of Sale is the correct answer because it serves as a legal document that transfers ownership of personal property, in this case, the refrigerator, from one party to another. When a buyer like Jack has a Bill of Sale, it provides clear evidence of his ownership claim over the refrigerator as specified in the Real Estate Purchase Agreement. This document can detail the item being sold, the parties involved, and the terms of the transaction.

While a statement in the purchase agreement indicates that the refrigerator is included in the sale to Jack, it does not independently transfer ownership. A certificate of sale and a deed pertain to real property transactions and are not applicable for the personal property item in question, which is why they would not serve Jack's purpose for proving ownership of the refrigerator.
