Editing Power of attorney (section)

===Springing===
In some U.S. states and other jurisdictions, it is possible to grant a ''springing power of attorney''; i.e., a power that takes effect only after the incapacity of the grantor or some other definite future act or circumstance.<ref name=ppl /> After such incapacitation the power is identical to a durable power, but cannot be invoked before the incapacity. This power may be used to allow a spouse or family member to manage the grantor's affairs in case illness or injury makes the grantor unable to act.<ref name=spring>{{cite web|title=Financial Power of Attorney|url=http://www.aarp.org/relationships/caregiving-resource-center/info-11-2010/lfm_financial_power_of_attorney.html|publisher=AARP|access-date=5 May 2017}}</ref> If a ''springing'' power is used, the grantor should specify exactly how and when the power ''springs'' into effect. As the result of [[Health Insurance Portability and Accountability Act|privacy legislation in the U.S.]], medical doctors will often not reveal information relating to capacity of the principal unless the power of attorney specifically authorizes them to do so.

Determining whether the principal is "disabled" enough to initiate this type of representation is a formal process. Springing powers of attorney are not automatic, and institutions may refuse to work with the attorney-in-fact. Disputes are then resolved in court.

Unless the power of attorney has been made irrevocable by its own terms or by some legal principle, the grantor may revoke the power of attorney by telling the attorney-in-fact it is revoked.  However, if the principal does not inform third parties and it is reasonable for the third parties to rely upon the power of attorney being in force, the principal might still be bound by the acts of the agent, though the agent may also be liable for such unauthorized acts.
