Wait, Slater and Gordon are doing what? Seriously I wouldn't go near that firm with a 10 foot pole; any decent solicitor would advise getting a will done professionally. The legalities behind a will are actually quite complex and serious mistake can be made. The idea that a major law firm would imply, through making them available, that an online will is okay is very worrying.
