Help me word a consent form?

Ok so I found a way to get out of an hour long car ride with my ex to get my son’s passport…
I just need to bring a notarized consent form from him but I don’t know how to word it… so far I have

“I, [dirty; cheating; ex,] give permission for my son to obtain a passport. His mother [beautiful, awesomely great, person I never should have cheated on…aka krose1223] has my permission to complete necessary forms without my presence.”

blah blah blah. It sounds so weird and dumb to me. HEEEELLLLLLP!!
