I think that writing a will is such a loving and considerate thing to do, and it can be simple.
Ours cost £2.99 from the stationers. If your affairs are simple, writing your own will is perfectly legal here in uk, cheap and easy to do (we had a lawyer glance over ours and she did not charge for that). Of course charities often offer free will-making with a lawyer/solicitor and ask for a donation from your estate in return, so at the time of making it it is virtually free.
At the stressful time of a death it can be one less difficulty for those left behind if there is a will filed where it is easy to find. Knowing what the person who died wanted is a comfort worth having, and since it comes to us all......maybe we should talk about it, be kind and caring, and write our will.
(We wrote a covering letter to our children with ours saying that just because we loved all our stuff didn't mean that they had to love it too, and that they must feel free to dispose of it entirely as they wished!)
