I'm my mothers POA. Her car is registered to her however, I'm the primary driver as she doesn't drive anymore. I need to renew her registration and realized that her state ID (not drivers license because when we moved to NJ from NY she didn't want to drive anymore) expired in April of this year. How do I go about taking care of all this as her POA? I cannot seem to find any information on the DMV website. I assume I have to do everything she would do and just bring the POA as proof. Does anyone know?
