Just recently myself 3 sisters and brother lost our father, we have been devestated by this as you can imagine. Our youngest sister is 18 and was his biological daughter, our dad divorced our mum years ago but we all stuck together, our relationship didn't change at all, even after our mum remarried every xmas, family party or holiday was all together. 20 years as being our father we have suddenly been left with a big hole in our family, but now we know that as we have been grieving our younger sister has appointed herself to be in charge of all financial things and has taken all documents away and won't tell us anything like we don't matter, from the first night she has removed things from the house including paperwork without us seeing, we are now asking what's happening with things and she is being very secretive , we find it hard to believe there wasn't a Will he would of wanted us to all benefit as well as his 5 grandchildren really don't know what to do???
