This is a llittle more complicate than you might think. If you are just asking your mother to sign a DPOA, she needs to be comptenet to do so. If she is not comptenet to sign a legal document, anything she signs would not be valid, including at DPOA. However, even incompetent people have moments of lucidity, so that can be a more involved issue. Please consult with a lawyer.
