We know of a case where mother and father signed their house over to their D without making any provision for themselves. After his wife died, the D had him removed and sold the house.
I have heard third had accounts of this sort of thing happening, but it has never happened to anyone I know first hand.
Of course it is legally possible if the parents haven't plugged the gaps in their will, but the gaps can be plugged easily enough, and I can't imagine that many children would behave like this anyway.
We considered doing it, but in the end decided not to, as we felt that as the house and half of our savings would be 'in limbo' (not belonging to the children until the death of the surviving parent, and not belonging fully to that parent either), we would lose control over what happened to us if we needed care.
It is a shameful state of affairs that people even need to think about doing something like this, IMO. I am a firm believer in everyone paying their way through life, but I get so fed up with some people getting things free (whether it's pensions, access to means-tested advantages or social care amongst other things) that I can well understand why people look for loopholes.
It needs sorting out fairly ASAP, in line with Johnson's broken promise of ages ago.
Also. When people go on about those who bought houses for £1 and are sitting on millions, do they realise how London-centric they are being? For much of the country, paying for care on the strength of the money in their homes sill clean them out very quickly. The famous 'boomer' who is sitting on millions and a fat pension earned by her husband is a rare breed in the pretty much anywhere but the SE. It is one thing to eat into your children's inheritance, and quite another to wipe it out altogether.
This is yet another anomaly that is always overlooked when these things are discussed and when policies are made.
