Immediate durable power of attorney
An immediate durable POA gives your agent authority as soon as the document is executed. Many people hesitate at this, worried about handing someone that much power while they're still healthy and capable. That concern is understandable, but it misses something important: the document only grants authority. Your agent still has a fiduciary duty to act in your best interests, and you retain full control over your own affairs as long as you have capacity. The agent's role is to step in when you cannot, not to run parallel to you.
The practical advantage of an immediate POA is speed. If you have a medical emergency tonight, your agent can act tomorrow morning without needing a physician's certification first.
Springing power of attorney
A springing POA holds the agent's authority in reserve until a defined event occurs, most commonly a licensed physician certifying in writing that you lack capacity to manage your own affairs. Some people feel more comfortable with this structure because the agent cannot act until the document "springs" into effect.
The tradeoff is real. In a crisis, obtaining that certification takes time. Banks and financial institutions may also be slower to honor a springing POA, since they need to review the triggering documentation before releasing access to accounts. That delay can matter when bills are due or medical costs need to be paid immediately.
New Mexico follows the Uniform Power of Attorney Act, which gives principals flexibility in how they structure the effective date. An estate planning attorney can help you choose the approach that fits your family situation and your level of trust in your chosen agent.
