M passed away 2 months ago. We believe she re-wrote her Will when she had Dementia. She did go to a solicitor & chose executors. Are family allowed to know the contents of the Will & if so when? I am concerned she may have changed her Will when not able to understand a family situation & may have removed my sister from receiving a share and given it to a person who 'befriended' her in recent years. What is the protocol in such a situation?
