Power of Attorney: What does “durable” mean anyway?

The term “durable” when applied to a power of attorney, simply means that it continues to be effective and binding even after the person signing it has become mentally incapacitated. There are some instances in which someone might prepare a non-durable power of attorney (which would terminate when the person giving the authority loses mental competence) but in the context of estate planning, it is almost always preferable to have a “durable” power of attorney.
