I hadn't realised, until I read about this case, that people could be classed as dependents when over 18 (Inheritance (Provision for Family and Dependants) Act 1975)

Personally, I don't think the daughter should have been given anything if that was the wish of her mother (but clearly that act says otherwise). The only way round it would seem to be to give your money away to whoever you want before you die, or spend it. Obviously that isn't always practical though.
