With the huge number of cars on the road in the most populous state in America, it's not surprising that a California Lemon Law lawyer might be required should you find your vehicle is a lemon. Generally based on the validity of a warranty and a manufacturer's responsibility to honor that agreement, you might find that you have one of two kinds of warranties. The first kind is called an express warranty and is an agreement in written form. The second kind of warranty is an implied warranty and is typically not written down.
