Hi Ringi
There is no word version of the form and you have to use the form sent you, but that does not stop your wife from typing up the answers. In each of the boxes which you need to answer just put. "See additional sheet no....." and then type up the answer in word and allocate a number for each sheet. Make sure she types name and national insurance number on each sheet too. Lots of people don't write on their forms.
