Good morning I need The requirements for a power of attorney and how much they cost, thank you

You need to bring the Ecuadorian ID or passport, and the data of the person to whom the power of attorney is granted, I don't know if all the types can cost the same but they are $ 30.

I need a phone number with whom I can contact to find out how to operate my Ecuadorian ID and what I should do

Please tell me if you are attending on Monday
