Have you already reviewed the papers with an attorney? If not, you should just take the papers and tell her you'll be in touch so you can read them and have the benefit of counsel.
If you understand them and agree with what they say -- or are at least resigned to not fighting them -- just sign them with no comment and be on your way. Asking her if she is sure this is what she wants will come off like pursuit, IMO.
