Just to be clear, I am not in the UK, so legal/tax implications may be different.
My elderly DM's accountant recently advised her to wind up a self-managed pension fund which my DF oversaw while he was alive. Accountant's reasoning was that DM has a high income from other sources and does not need the pension income. It would be most tax efficient for her to liquidate the holdings and divide the proceeds between my siblings and I - there would be no tax payable on these 'gifts'.
This suggestion came as a surprise to me but I welcomed it because although we are comfortably off, we have had a lot of high costs lately, issues with damp, house repairs, DC going to university etc. My DBs have higher incomes and much younger dc. Between them, they have decided, for reasons known only to themselves, to do everything they can to prevent this distribution. They have insisted that this amount should remain 'part of the estate'. They have lied to DM, telling her that there would be tax implications (the accountant confirmed this wasn't the case). They have tried guilt-tripping, telling DM that she is dismantling our DFs years of hard work (also a bit silly, as DF had multiple other investments which will not be affected). They have repeatedly said that it is best to keep the estate intact.
My DM has stressed to all of us that she simply wants to divide the proceeds three ways but my DBs are sabotaging the process by ignoring her instructions (one needs to assist with paperwork/transfers relating to wrapping up the fund). They are making her anxious and stressed because she feels under pressure to do as they say but doesn't want to.
My DBs and I do not get on. I find them very selfish, shallow and money-oriented, they look down on me because I do not have a prestigious, ultra-high paying role (my career is perfectly respectable). They may also resent the fact that I and my family are closer to DM than they are, but this is mainly due to me making more of an effort.
AIBU to wonder whether this behaviour is elder abuse? What could DBs motivations be? And How should I respond?
