I am sure that this situation is not unique and my understanding is that the RNRB will not apply in these circumstances which appears to be inherently unfair.
I have an unmarried couple. He has children from his first marriage and they do not have children together.
If he dies first, he wishes for her to be able to remain living in the property and then on his death for his share to pass to his children.
If she dies first then of course his estate benefits from the relief but if she benefits from the right of occupation then the relief is lost.
Am I correct and, if so, is there anything that can be done?
