I've been thinking of this recently too. My friend's a solicitor and I spoke to her about wills. She says in my area unsure if it's UK all over. There is a thing called will aid. Places like blackadders etc do this and request you give money to charity of their choice I guess it's at a lower rate than they would charge. I think it's in Nov but I'm very anxious about this so still haven't done anything with it. Talking about death or anything like this makes my anxieties heightened massively.
