A springing power of attorney is a power of attorney that only takes effect once a specific condition is met, most often a doctor's confirmation that you're incapacitated. Unlike a durable power of attorney, which is active from the moment you sign it, a springing one stays dormant until that trigger event actually happens. That can feel appealing if you're not ready to hand over authority while you're still fully capable of managing your own affairs. The tradeoff is practical: proving the triggering condition can take time, medical documentation, and sometimes even legal steps, which can slow your agent down right when speed matters most. Because of that delay, many estate planning attorneys lean toward durable power of attorney instead, reserving the springing version for people who specifically want that extra layer of control.
