Last Will Testament???

I believe 18 is old enough to have a will. You may not have a lot to leave to people but nonetheless your wishes can be recorded in a will. It sounds really silly, but it's a good idea to review your will every few years, things change with time and you may find that your wishes change too

i dont think there is a set age for this to be done all depends on the individual and what they will be leaving behind and who they will be leaving it to. i think if there people that it will be left to are civil are normal then there is no rush if there will be disputes then get it done cos you never no what might happen. but what ever you do dont tell people what there getting could you greif if they start arguing about it

18.. or whenever you think about having a child, a house, or anything value.

If you're mature enough to be asking this question, then you're mature enough to have a will in place. I'm only 23, and I have a living will in place. There's no way I want to be kept alive through artificial means.
