(UK law) My father just passed away from a serious illness. In the last days of his illness someone had a solicitor send letters making false accusations of sexual assault from many decades ago, and demanding money. She knew he was very soon to pass away. No criminal or civil complaint had ever been made before. As I'm the executor of the will, that person is now having their solicitor chase me for money. Can I just ignore this, as the claim is false, and has no authority? She has presented no "evidence" and there is no "witness". Thank you so much.
