Final answer:
Mork and Mindy should make a written request for the antique clock to be included in a written addendum to the contract of the home purchase negotiation to ensure it's documented before the property sale is finalized.
Step-by-step explanation:
Buyers Mork and Mindy, who are interested in purchasing an antique clock in a Delaware home, should express their intent as part of the home purchase negotiation process. To officially indicate they want the item included in the sale, they should make a written request to the sellers or their real estate agent, stating that the antique clock should be included in the purchase agreement. This request can be part of an addendum to the contract. It's important that this is done before finalizing the sale to ensure that there is a binding agreement for the inclusion of the clock. Additionally, stating these terms clearly in writing helps prevent any misunderstandings about which items are considered part of the property sale.
