That is a hard question as trial attorneys often create their own guide books and build their trial skills over many years. This is not a subject that may be learned by a book; but there are certain practice guides that most NY lawyers have come across or regularly reach for when refreshing issues on a case by case need.

James publishing offers an awesome civil practice guide which clearly and simply explains all the rules in floating a case before trial. I like Friedman's book on Objections Practice.
However, just as I would be a little lost in repairing my car's transmission by reading a book, you too may find yourself hobbled by the complexity of the legal process. Lawyers have to endure at least three years of specialized schooling followed by extensive testing and years of experience. It's akin to playing a piano before a live audience having read a book about music theory. The results will be disastrous and you will be the loser.

If the case is regarding a significant sum or principal, hire an Attorney.
