So as above really, MIL has dementia (although still awaiting diagnosis), it seems likely that she has had it for some time - looking back maybe as long as 7 years. We have brought up the subject of POA and wills several times over the last couple of years and have been met with a flat no. I have scoured the internet for articles to send on explaining why it is a good idea and have looked through forums for ways of presenting it, and still a firm no. We are now at a point where I'm not sure we could ask MIL to sign it as I don't believe she would actually have any comprehension of what she was doing.
FIL is 10 years younger than MIL and still in good health and determined that POA is not required, it is clear now that we are not going to get it and so I wonder what this looks like going forward. I'm well aware that we could potentially be looking at deputyship in the future and that bills and finances may become impossible. But, I'm also aware that sometimes things do not play out like they are supposed to and I wondered if anyone had any experience of a parent with dementia with no POA and a well husband/wife where the lack of POA wasn't too much of a barrier.
