Chris, sorry to be pedantic, and I wouldn't normally correct you but......
giving money away to avoid care home fees is not illegal. Someone can give away the whole of their estate, however, if a "significant" reason is to avoid care home fees, the Council can take the view that the donor has "deemed" capital and can charge the assets donated with the fees. There is also no time limit. So the Council can, in theory go back as long as they wish. It will all depend on the circumstances at that time. For instance, someone aged 50 in good health who puts their assets into trust to avoid a potential Inheritance Act claim by their step children would not fall foul of the "divesting of assets" provisions. However, someone aged 86, whose long term care is imminent who transfers their house to a child may well do so.
That link is terribly misleading (but what can you expect from our esteemed government!?!
