Hi Mitoval
There's no PIP2 form available to fill in online because all claims have a unique code which identifies the claimant.
There's a PDF sample form available that you could use to know what questions are on the form.
assets.publishing.service.gov.uk/governm.../dmgch42.pdf#page=40 You could type out your answers and then ask someone to fill out the form for you or cut your answers out and stick them on the original form, if there is not enough room in the box for your answer then use the space available towards the end of the form and add extra pages if required, remember to add your name and National Insurance number to each page and number the pages. Make sure you make a note at each question if your answer carries on another page and reference the page number where the notes carry on.
Don't forget to take a copy of your form once completed before you send it off.
