Maddiedu, I get the impression that your late husband and your daughter have convinced you that you are incapable of managing your finances, which I can’t imagine are very complicated. Both of them have also convinced you that your dil is a bad lot because she came from a council estate and her family claimed benefits, but presumably that isn’t the sort of life she herself lives, having been with your son for 20 years and given you grandchildren. Yet she is described as an outsider after all this time and your husband instilled in you a fear that she might somehow get her hands on ‘family money’ and that this money must stay in the family at all costs. But as has already been said, when your daughter got divorced some of the money she had been given presumably went to her ex-husband?
I also get the impression that your daughter is controlling your money now and doles a bit out to you when you ‘need’ it, with you having no idea how much money you have or where it is. I hope I’m wrong, but could your daughter be trying to get you to leave everything to her so that your son doesn’t get to see what she has been helping herself to? In other words, is she stealing from you? From what you have said, she wouldn’t see her brother and his children were all right.
Your husband wanted the money left to the children. In my opinion you should do what Dinahmo suggested - half each, but deduct from your daughter’s share an amount equal to what she has been given over the years and whatever she may have helped herself to. That’s completely fair.
You definitely need to see a solicitor to make a will, and don’t allow your daughter to go with you or dictate what is in it. You also need to talk urgently to your bank about your financial situation. I hope you know which bank your husband used? If not a solicitor can help you. The money may be spread about but the bank your husband used should be where you start. You need the bank’s help to regain control over your money and to start managing it for yourself. They will be able to help you do this. You are perfectly capable of doing it, don’t let anyone tell you otherwise. Maybe your son can come along with you for support? I think you should be confiding in him and I’m sure he can help you to take back control from your daughter. I don’t believe she has been acting in anyone’s best interests but her own. You are not betraying your husband in doing this. He would not want your daughter to be abusing you in the way that I believe she is. Feel free to PM me if you wish to discuss anything in confidence. I’m a retired solicitor and can’t give you legal advice but you can message me in complete confidence. Sadly, I have seen this situation before in a professional capacity - and it was the daughter who was helping herself to the money on the basis that mum ‘couldn’t manage’.
