most local authorities are aware of these and will ask the question 'Do you or have you ever owned a property?' If the answer is yes, they will want to know what happened to it and if and why it was transferred.
If the reason was to avoid care costs - a move known as deprivation of assets - then they can treat you as still owning the property, calling it 'notional capital' and refuse to meet any care costs until such a notional amount was depleted to the means-test limit by paying for the care.
There is no time limit as to how far back the local authority can go to identify the gift as deprivation of assets.
