retirement fund

Gifting the house to the wife

Q: A man passed away leaving behind a wife and six children. In his lifetime, he contributed monthly towards a retirement fund, and whilst alive, he had written and signed that he had made his wife 100 % benefactor of this fund. In addition, he had a house in which his wife and children live. In his lifetime, he mentioned to his wife that 'this house is for you'. Does this fund and house form part of the inheritance to be distributed?
