...but I don't even know if or how I can?
Background: My aunt A just died a few days ago in hospital.
My Dm, aunt B and aunt C took turns taking care of Aunt A for years. Though for a while aunts B&C were not allowed in her bungalow (Aunt A suspected them and one of their husbands of pilfering from her stashes on money) Dm tried to get her to put it all safe in a bank account but she still kept large amounts at home.
The rest of the family is angry at aunt B and aunt C for making her last days agony. She was on palliative care and had essentially been knocked unconscious with morphine. Her legs were ulcerated and the nurses had stopped dressing them to spare her the pain as she was near the end.
Aunts B and C went into hospital on her own once and made a huge fuss about the doctors trying to kill aunt A and how dare they not take care of her, prompting the doctor giving her something to bring her out of a coma.
Her last days were deeply unpleasant 
Fast forwarding to today: Aunt B + C have produced a will. Essentially leaving everything bar a couple of bits to them and their husbands.
The thing is this will is scribbled on a piece of paper, in different coloured inks and also crossed out bits. Aunt B is emphasizing how this will is years old. Her and aunt C are 'witnesses' and executers.
There is a mention of lots of jewellery items on the will. Aunt B and Aunt C told my Dm they went to the bungalow to look for it but it's all gone now and they don't know where.
Dm knows there was an inexpensive necklace that aunt A wanted her to have for sentimental reasons that has apparently disappeared in to thin air.
There is no mention of a sizeable amount of money in the will that Aunt B and C claim aunt A 'wished' them to split. Only mention of money is three sets of £200 to their husbands and my Dm.
I've had Dm here in floods of tears this morning not knowing what to do. I've told her to go and get a copy of this 'will' but after that I'm not sure what it is we can do?
I know people say it all the time but it really isn't about the money, it's devastated my mum that her sisters have done this and I don't want the thieving fuckers to get away with it.
