I am in the process of moving my Mum nearer to where I live as I am retired and better placed to look after her. Both my sister and brother are still working and don’t have the time. There is not much of a margin left over for her to do up the bungalow after the sale and purchase. We would like to lend her some money to make improvements to help her as she ages. However we need to ensure that this is ring-fenced so that it’s not part of her estate when she passes and therefore classed as inheritance which would be split 3 ways. Can anyone advise the best way to do this please?
