My dad died last year.. been married to my stepmother for 40 years.. we have always got on well.
They had mirror Wills. So my step mum inherited everything. House worth 1.2m (nothing special but south east).
Wills say everything to each other and then everything between the four of us. Two children each none joint.
Step mum just passed and it turns out she changed her Will 6 months ago (when in sound mind ) and left us out leaving all to her two kids.. ( they are mortified- genuinely) want to know what they can do... can they change it to make it as our dad had wanted it ?
