POA, in this case, stands for power of attorney. These documents determine who will be making financial or health care decisions for you when you are unable. If you choose not to create these documents, it can cause confusion and possible court proceedings. In Arizona, a guardian may need to be appointed by the court to handle medical and care decisions for you, and a conservator may be needed to manage your finances. Both put decision making into the court’s hands instead of your own. Fortunately, both can be avoided by properly executed powers of attorney.
