Dh and I did our Powers of Attorney (both financial and welfare) back in September, naming each other and my lovely SIL. They can act "together or separately" (I trust SIL competely, as well as, of course, Dh
).
I've just checked the paper work and it says....
2.7 I have considered how my incapacity is to be determined and have decided it shall be so where my welfare attorneys reasonably believe that I am incapable.
....
2.12 This deed incorporates the necessary “capacity certificate” in the form prescribed by the 2000 Act.
I know that are are massive delays at the Office of the Public Guardian so they're in the "queue" and they've not yet been registered, but the lawyer assured us that if (heaven forfend) the powers of attorney should be needed, the OPG would expedite it.
My dad ended up having to put my mum into a home, using his power of attorney (which fortunately they'd both done for each other just before they went on the holiday where she acquired the head injury that ultimately ended up killing her 5 years later through a head injury induced early onset dementia
) with an emergency admission, rather than one of the ones he'd been looking at, as he recognised he wasn't coping and she'd had yet another fall. He ended up having some money paid back after (I think) the Social Work assessment confirmed her needs - but payment was never the issue as he just wanted her to be in a place where she would be safe.
I agree with others that you need to rapidly check out local suitable care homes. Mum needed somewhere with a dementia unit rather than just a "plain" nursing home.
I also agree that you need to be present at the "discharge" meeting - and make it absolutely clear that you will not be present at your relative's home when she is discharged, nor overnight. Ask very explicit questions about what risk assessments have been done.
You can't stop the discharge but you can advocate for a suitable care package. It may be that your relative ends up going somewhere temporarily until you can sort out somewhere better.
Even in the nursing home, mum ended up having to have pressure alarm pads around her bed as she didn't understand that she could no longer balance/walk and would fall every time she tried to go to the toilet.
I wish you well
