The minute you read something and you can't understand it, you can be sure it was written by a lawyer. Then, if you give it to another lawyer to read and he don't know just what it means, then you can be sure it was drawn up by a lawyer. If it's in a few words and is plain, and understandable only one way, it was written by a non-lawyer.
