I'm not suggesting tht this is your motivation, OP, but to anyone thinking of this in order to safeguard assets against care home fees, I'd say please think very carefully.
Aside from the 'deprivation of assets' question - and unsurprisingly local authorities can be exceedingly eagle-eyed on this - there is another aspect many people don't think of.
I have heard of people who think it's a simple matter - if they money has been squirrelled away and the person needs a care home, then the local authority will pay. In practice, where families are dependent on the LA it's often the case that families/carers can be on their knees, stressed and exhausted out of their minds (I am thinking of dementia here) and social workers will still find reasons not to fund a care home. They are all under pressure regarding costs, hardly surprising when you look at care home fees, and it's not at all unheard of for them e.g. to say they can't put the person in a care home if they don't want to go. And of course, virtually anyone, with or without dementia, will say, if asked, that they don't want to go. Particularly in the case of dementia, when the person will very be likely be quite unaware of the strain they are putting on their family, and may well believe there is nothing wrong with them (as was the case with my mother).
We had dementia in two relatives over many years, my mother and my FIL, and I have heard of so many cases like this, with family carers right at the end of their tethers. So I am just pointing out that it's not as simple as some people like to think. Both our relatives were self funded, and TBH, having heard all I have, I think it was a 'luxury' to be able to self fund and to be able to choose the time and place without being dependent on the tender mercies of social services/LAs at all.
