This is absolutely awful, I am so, so sorry you are going through that nightmare. You and your poor husband, suffering like that it's horrendous. IHT can be incredibly cruel and just as we are grieving.
People picture IHT as affecting the wealthy, but actually a lot of us aren't wealthy at all, but our parents lived in a house that due to being in London changed from being very modest to expensive over the decades. We don't have anywhere near the funds needed to pay IHT before the house sale.
Right now, our surviving parent is still alive, but has been near death several times. Doctors have given us the 'is passing away' talk in the side room.
I am dreading grieving and having to deal with IHT without the funds to pay. I have been through years of cancer treatments, I literally can't face what is ahead with this IHT nightmare. This is why I am trying to get some of it sorted in advance, like maybe the forms and solicitor? We can't delay applying for probate considering the house can't be sold till that comes through. The parent's neighbour's house was on the market for 2 years recently.
I am thinking of you and your husband, @Gingercar
