It's a pity they don't do what the Passport Agency does for renewals. You complete the renewal form on-line and they then send you the completed forms so you can sign them and add any evidence such as photos.
Or just let you do it on-line - so much easier than writing. But I can just hear them saying 'Let your husband (or someone else) complete it for you then.' I am extremely fortunate because I have never seen the form you are referring to but I assume that it asks for some very personal information that you might not be happy disclosing to the form filler, even if it is hubby.
