My dad was sectioned under the mental health act. He was having brain bleeds which led to vascular dementia, he never came out of hospital. He and my stepmother had mirrored wills leaving the estate to her children and my dad's children upon both their deaths. But after my stepmothers death 7 months after my dad died, I found out my stepmother changed her mirrored will benefiting her children and l lost my inheritance. I was a executor on both Wills until my stepmother changed her Will. My dad's probate is still being going through. Is there anything I can do. Thank you.
