If you have a simple family history that does not involve multiple partners or divorces, plus economic arrangements that don't extend beyond owning your own house in the UK plus a pension and few investments, there is much to be said for buying the Which? publications book (in Waterstones or similar) called 'Wills and Probate'. It tells you how to DIY for the cost of the book. Mine is a reprint from 2003 and it cost £10.99p at the time. Well worth the money. I hate spending money on solicitors at about £100 per hour if I don't have to, don't you?
