Before you sign your house over think about the future and what could happen. Are you expecting to carry on living in the house? If you are living there and say for instance one or other of your children decide to divorce the spouse could have a claim of half your childs assets, This could mean that they may have to sell your house to pay them.
Or have you thought about one of the children becoming bankrupt....please think hard, I know of someone who did sign their house over and within 2years they were homeless and the council refused to house them because they said they had only themselves to blame because they gave their house away
