I have concerns that there is a conflict of interest arising with the handling of my mother's deceased estate. Briefly, the situation is thus: My sister and my Mother's solicitor were the Enduring Power Of Attorneys for my Mother. They acted severally. During this time the solicitor also acted as my sisters solicitor when aspects of the EPOA were contested. My mother has now passed away and my sister wishes to use the same solicitor to do the probate of the will, whilst still engaging the same solicitor to fight me in disputing the will. This same solicitor was also the witness to the will being signed. My sister and I are both executors of the will. I feel that this scenario will not lead to the best outcome for myself. I also wonder if this interweaving of affairs actually above board?
