The book has some extremely useful information, however be forewarned that if you enter a court In Pro Se, the judge is very likely to rule against you out of dislike for us mere mortals presuming to stink up their court room with our pretentions (or lack of funds to pay a Lawyer to actually do something useful).
Having hired numerous Lawyers to handle various matters, I can say with complete confidence that if our homes were built by them, civilization as we know it would simply cease to function. They are the most overpaid, universally incompetent, arrogant, dimwitted and unscrupulous humans on the planet (though one wonders if they are indeed Homo Sapiens or rather some aberrant mutation). They are absolute proof that there is no such thing as Cosmic Justice, because if there were such a thing, then all Lawyers would die of leprosy or some other horrible cancer. Instead they die old, fat and happy with the ill gotten gains of their endeavors.They get away with their crime against mankind, because they and their ilk make the rules, while the rest of us are out working hard to make the world function.
If you need to purchase this book, you have my most profound condolences and I wish you the best of luck, you are going to need it.
