On the parking pass form, Block 25 is for the name of my sponsor, who is my P2B. However, there is also a 'signature field' in that block. There is nothing in the instructions about this field, and when I google Form 5512/1, not a single version has this signature field. I am assuming that my son signs this field next to his printed name, but I don't like to ass-u-me. Would it be for him to sign, or for office use?
