If Della accepts the lower purchase offer under family pressure, what might she later claim?

If Della accepts the lower purchase offer due to family pressure, she might later claim that she was under undue duress. This claim would signify that her decision to accept the offer was not entirely voluntary, as outside influences (in this case, pressure from her family) compromised her ability to make an independent and informed choice. Undue duress is a legal concept that refers to a situation where a person is forced to act in a certain way through threats, coercion, or pressure, which can significantly affect the validity of a contract.

In situations where a party feels that they were not able to freely make a decision due to such external pressures, they may seek to challenge the validity of the agreement later on. This can be particularly important in real estate transactions, where decisions can have significant financial implications.
