Hi WimbledonP
I'm sorry to hear about your partner and his terminal illness. Difficult for you both and your loved ones.
There's no easy way to give you the information below.
If your partner has been given less than 12 months to live, his PIP can be fast-tracked. The information is on the government website.
www.gov.uk/pip/claiming-end-of-life If he has more than 12 months to live - it will just go through the normal process. No one is going to be worried about you having been on holiday. Tell the truth on your form. The important thing is his condition now as you put in the application and his is affecting his daily living and/or mobility.
If you have any other questions come back and ask.
