When creating a power of attorney, the most important step is to understand why you want someone to have control over your legal or financial matters. There are many reasons why people create powers of attorney– the most common being when individuals want someone else to make decisions for them when they lose mental clarity with old age. Maybe you’re in the military and want someone looking over your affairs while you’re deployed. Another good reason to create a power of attorney is to have someone available to act for you if you suffer a devastating medical injury that leaves you unable to handle your affairs.
