In Lamb v. Scott, 643 So. 2d 972 (Ala. 1994) a mother gave a durable power of attorney to her oldest daughter, authorizing the daughter to manage her affairs. A year later, the mother executed a will leaving all her property, including a farm, to her two daughters and her stepson, in equal portions. The oldest daughter, purporting to act pursuant to the power of attorney, conveyed the farm to herself and her sister, to the exclusion of her stepbrother. The Court held: "One who accepts a power of attorney covenants to use the power for the sole benefit of the one conferring the power and to use it in a manner consistent with the purposes of the agency relationship created by the power of attorney." Lamb, 643 So. 2d at 974.
