A typical Power of Attorney is often referred to as a “General Durable Power of Attorney.” This document gives another person, called the “agent,” to act on behalf of the “principal,” which is you, in almost matters of financial affairs. It is effective as soon as everyone signs, and does not expire (that’s why it’s called “durable”). Sometimes people don’t want their Power of Attorney to take effect right away, but only when they become medically incapacitated and unable to make their own decisions. Thus, the Power of Attorney only “springs” into effect when this incapacity occurs. The way to do that is to add language into the Power of Attorney which requires a letter from one or two doctors certifying that the principal is unable to make their own financial decisions.
