From a property law point of view the council has no claim on the house because the three year discount period has long expired. So if the house was sold the council couldn't claim back any part of the discount that you parents were given when they bought the house. However that is a completely different issue from the cost of care home fees and the equity in the house could be used for that if neither of your parents has other means to pay their contributions towards care home costs. When you paid for the house you should have been advised to take a security over the house or at least enter into a contract with your parents to reflect that you have paid for the house and that you were to be entitled to a share of it. Alternatively, the title should have been transferred to you once the three year discount period had expired. If none of these steps were taken, the local authority can ask for the sale of the house to contribute to care costs. It may be that if it is explained to them that you lent the money for the purchase that they will exercise discretion and reduce the amount that they would be seeking.
