Last summer, I sought some advice on here regarding will-writing. My situation is such that an off-the-shelf, fill-in-yourself will wouldn't have cut it, but I felt stumped as to who to go to get it done, getting different advice from different people, and getting so far with a particular will-writer who was pretty awful (and bank breaking).
In the end, I opted for a will-writing solicitor who is also a Mumsnetter :) and who really has been brilliant - thorough, fast, and reasonably priced.
So really, I'm simply posting to say that if you're thinking about getting a will drawn up, and haven't decided yet on who to get to do it for you, consider Marlow Wills. Strongly recommended.
