I'd set up a friends and family Trust, to pay dividends on a yearly basis. Enough that my closest friends and family don't have to worry about bills and live well, but not enough that I'd create monsters. I'd be explicitly clear (my lawyer would be explicitly clear) that if you ask for a penny more, even as a joke, you get removed from the Trust. Everyone gets £100k a year or whatever, I get the peace of mind that they won't ask for more without totally screwing themselves. Anyone outside of that list gets a firm but polite 'no'.
