Legal problems on construction projects can be very expensive, so if you're a contractor or construction business owner, it's a good idea to keep yourself educated on the relevant issues. Fortunately, there are plenty of books and seminars out there that can help. Most don't cost much, and they're worth every penny in the long run.
Don't be afraid to ask a potential construction law expert about their credentials and education. As volatile as the construction field can be, you need a lawyer whose credentials are rock solid, so they can guide you effectively if something should go wrong.
