We advise all of our clients to execute durable powers of attorney - appointing a trusted family member or friend to handle financial and legal matters for them in the event of a disability. This ensures continuity in paying bills and handling personal business, can help prevent loss of funds and avoids the need to go to court for the appointment of a guardian or conservator.Clients might expect these documents to take effect only upon their incapacity, to be "springing", rather than effective immediately upon signing. But almost all of the durable powers of attorney we prepare for clients are immediately effective, even if they will not be used until needed.
We do this because these documents are only useful if they are accepted by third parties. If a bank, for instance, is presented with a springing power of attorney, it will need proof that the grantor is incapacitated.
They will most likely accept a letter from his or her doctor to this effect, but do we really want to make the person appointed under the power of attorney (the "attorney-in-fact") have to go to the trouble of getting such a letter. In all likelihood, they will already be overburdened dealing with the grantor's illness while also trying to maintain other work and family responsibilities. To require that they seek out a physician's certification of incapacity will only add to their tasks and delay their ability to act on behalf of the loved family member or friend.
The only reason to make a durable power of attorney springing is to make sure that the attorney-in-fact does not act prematurely, before the grantor's incapacity. If the grantor is afraid that this might happen, then she should reconsider who she is appointing. (Of course, some clients don't have a lot of options as to who they can appoint.) And if the attorney-in-fact does exercise the power of attorney while the grantor is competent and without her permission, she can always revoke the instrument.
For these reason, we urge all clients to execute immediately effective durable powers of attorney as part of their estate planning. Only when they do not have complete confidence in the person they are appointing and have no reasonable alternatives should they consider making the appointment springing.
