A few threads on this Pusskin
TW's advice is definitely best but I note you have nt starred it
all but the simplest (all to my dear wife etc) should be done by a professional which doesnt cost nearly as much as correcting in the High Court
Simple is subjective - one thread thought simple was when you had two children and three step children and wanted to leave different proportions to each ! We all gasped.
Even if you get everyone who think they will benefit under your will
and get them to 'agree' - although what agreement do you need to "I am leaving you five million pounds." ?
It ccan still go horribly horribly wrong....see

altho my point is that the person drawing up ze Fransh will,
should have said, 'm'sieur, zees will will not get up and run....'
Everyone knows that a will under the Code Civil has to leave 60% to the kids.
