Looking for a bit of help re a friend.Her DB died suddenly,unmarried no children Will leaving all between 3 siblings Estate is about £750k so substantial IHT due She says she is looking to vary the Will to cut down the IHT .I am a solicitor but it is not my area My initial thoughts are that for a single person with no kids it is going to be quite difficult I know she will need to take specialist advice but it if any one has any helpful thoughts that would be great
