What should I do with my will once it is signed?

First of all, don't hide it. If your will cannot be found after your death, you will be deemed to have died intestate, so the effort you put into drafting it will have been wasted. Try to keep it somewhere where it will be protected from fire, flood, damage or loss.

You should try to provide your executors with information telling them where your will is stored and how to get hold of it after your death.
