What happens in these circs ?: both elderly parents alive ,mum took all dad's money into her name ,now she's died .

So these are not my parents.
Mum and dad had I think mirror wills and mum had son Joe being her power of attorney and all dad's money ie joint money went to mum. Mum has a new will with Joe being executor and possibly all money shared if she goes second ,hopefully if she goes first money goes to dad

His care home is being paid for.

Now mum has died first , does dad's original will come into play and who does his power of attorney.

Op mentioned a trust. Someone must be appointed to administer it.

Oh, yeah.

But she hasn't actually seen the will.

The whole thing is a pointless question!
