Another inheritance one:
My elderly DM (94) named one of my siblings as her sole executor in her will when it was written several years ago because my sibling worked in finance. Her will divides everything evenly, but there are complicating factors (family trusts, and properties to be distributed with equalizing payments to reflect different values). It turns out the sibling appointed as DM's executor is very devious and dishonest. I don't want to give any outing details but I have recently discovered they have behaved dishonestly over many years on a personal, financial, and legal level. DM is mostly oblivious. Does anyone have any experience of similar? Would you say anything or just leave things as they are?
