There are key differences in that case - 1) they were estranged and the mother said it was the daughter who made this happen which was untrue, 2) the claimant was an only child, 3) the mother left all the money to charity, in the OPs case it has been left the the mother's other offspring and, crucially, the OP also got a bequest, 4) the claimant had a need to rely on the money, we do not know the OPs financial circumstances and whether this applies, the claimant in that case had five kids and lived on benefits and a small income from her husband. And despite all this, she still only gut just over 10% of the whole estate. OP here has already had 5%.
The claimant was awarded £50k - how much do you think legal fees were for three court cases?
OP - my sister is not my dad's daughter, just my mum's, though he did adopt her. I think he feels that her own father (though legally he is not her father since my dad adopted her) should provide for her, and he probably will to some extent, also that my sister has made poor financial decisions whereas I have always been financially aware, and have bailed her out a few times.
But my mum was always very resistant to writing a will, my dad says he had to practically force her to. So when they did them, she just went along with what he said.
I do wonder if she just preferred to die intestate knowing that at least that way a proportion (if dad was still alive, all if he died first) would go to all three kids, I don't know. It's hard to ask her about this stuff. I did say to her a couple of years ago that when he dies I'll take her to the solicitor to write whatever will she wants but I am worried she's starting to go a bit doolally so she may not be able to.
Plus she's dopey about my brother so she'd probably end up leaving it all to him!
I can make redress by gifting my sister a share of my money, or doing a deed of variation for my inheritance to give her a third of mine. If my brother did the sane we'd all be equal. He won't though.
Mind you, my dad is very sick at the moment and I am here helping them for the second weekend in a row and there's no sign of my sister coming to see them, and she never came to my nan's funeral, so I do wonder if my dad has a point!
