Partners who are not married or in a civil partnership have no right to each other’s estate upon the death of one or the other. Say Mr & Miss have been together for 40 years and Miss has two sons from her previous marriage and owns the house her and her partner lived in. If Miss passes away nothing will go to her partner – all goes to her two sons including the house which will then leave Mr homeless. Everything can be provided for properly within a professional will. Miss could have could have granted Mr a “Liferent” in the property – this means he could live there for the remainder of his life, but never own it and it would pass to her two sons on his death.
