Offeror Incapacity Terminates Acceptance Power
Logan Lane offers to sell land to Lucy Liu. Before Lucy responds, Logan suffers a stroke that leaves him unable to manage his affairs. Lucy's power to accept the offer ends because the offeror's incapacity has the same terminating effect as death.
Principal Incapacity Ends Agent Authority
Lena Lawson grants her brother Lamar Lewis authority to manage her rental properties. A court later appoints a guardian for Lena after finding her incapable of handling business matters. Lamar's authority terminates during the period of Lena's incapacity just as it would upon her death.
Luis Lopez executes a power of attorney naming his daughter as agent to handle financial decisions. The document states it is durable. When Luis later becomes incapacitated, the agent's authority continues without interruption because the durable designation prevents termination by the principal's incapacity.
Incapacity Invalidates Consent to Invasion
Leo Lynch, suffering from advanced dementia, signs a consent form allowing a neighbor to enter his property. The neighbor later enters and damages personal items. Leo's lack of capacity to consent renders the entry an actionable intentional invasion of his interests.
Incapacity Prevents Parental Functioning
Lamar Lewis fathers a child but suffers incapacity before the child reaches majority. In construing a class gift from a third party, the child is treated as Lamar's child only because Lamar intended to function as a parent and the incapacity intervened to prevent that functioning.
Option Contract Power Survives Incapacity
Lucy Liu grants Logan Lane an option to purchase her business. Before Logan exercises the option, Lucy becomes incapacitated. The power of acceptance under the option contract remains intact despite Lucy's incapacity because the option prevents termination by the offeror's incapacity.
