Deed Signed by Attorney-in-Fact
Ariana Azizi granted her manager a power of attorney expressly authorizing real-estate sales. The manager executed and delivered a deed conveying Ariana's beachfront parcel to Anchor Bank at closing.

Durable Power Survives Incapacity

Common questions
Frequently Asked
5
How is a power of attorney properly executed when the principal cannot sign personally?+
A power of attorney is validly executed when the principal directs another person to sign the principal's name in the principal's conscious presence. Notarization creates an evidentiary presumption of genuineness but is not required for validity. The rule focuses on the principal's direction and presence rather than who physically holds the pen.
Does a durable power of attorney remain effective after the principal becomes incapacitated?
+
A durable power of attorney continues despite the principal's incapacity by definition. The durability feature prevents automatic termination that would otherwise occur upon incapacity. Agents may therefore complete authorized transactions without seeking new court authority.

What effect does divorce have on a preexisting power of attorney naming a former spouse?+
Divorce automatically revokes the former spouse's authority to act as agent under a power of attorney. The revocation occurs by operation of law unless the instrument or a court order provides otherwise. The former spouse is treated as having predeceased the principal for purposes of the nomination.
Supporting sources
May a court-appointed conservator execute a deed conveying the ward's real property?+
A court-appointed conservator is among the persons authorized to execute deeds transferring the ward's property. When the appointment order grants broad management powers without further approval requirements, the conservator may convey real estate. Good-faith purchasers relying on the recorded deed receive valid title.
Supporting sources
When may an agent under a power of attorney consent to a transaction that would otherwise constitute a tort?+
Consent given by an authorized agent is effective only to the extent it reaches the particular conduct at issue. A third party who knows the principal's actual preferences cannot rely on broad language in the power when the transaction exceeds those known limits. The consent defense therefore fails for conduct outside the principal's objectives.
