There are a lot of laws in this country. Most people do find the laws annoying from time to time, but they do exist for our own safety and protection. It's also easier to understand laws, sometimes, if you think about them as falling into different classes and categories. One of those categories is real estate. There is a great variety of laws that specify how properties can be bought and sold, what landlords and renters are permitted to do, and so forth. Real estate attorneys specialize in this type of law, and you can read about them on this website.
