As has been stated, this is a UK site and our laws are very different to those of the USA.

However, here in the UK it's perfectly normal practice for a solicitor (which is the term we use instead of 'attorney') to witness a will which he has drafted. There is no requirement to 'file' a will or to 'notorize' it. (We don't even have those processes. As long as the testator's signature is witnessed by two adults, a will is always valid). However only the original of a will is valid when seeking probate. (A copy has no validity).
