Final answer:
In the given scenario, Dorita may claim her acceptance of the purchase offer was due to undue influence from her son and his wife. This type of influence can affect the validity of a contract, as it raises questions about the voluntary nature of her agreement to the sale.
Step-by-step explanation:
The question pertains to a scenario where Broker Kenneth presents a purchase offer to Dorita, who is being pressured by her son and his wife to accept an offer below her asking price. If Dorita, under such pressure, accepts the offer, she may later claim that the acceptance of the offer was under undue influence. In the legal context, undue influence occurs when an individual is able to persuade another's decisions due to the relationship between the two parties. In this case, Dorita's son and his wife could be exerting such pressure on Dorita, which could potentially invalidate the contract. This situation highlights the importance of ensuring that all parties to a contract enter into the agreement voluntarily and without any coercive pressure.
