If you lie to your lawyer and the insurance company about past injuries and accidents, it doesn't matter how good your case is, the judge is going to make sure you lose.
Remember, insurance companies have access to vast databases about your private life, including past lawsuits, claims and injuries. Honesty really is the best policy. Tell your lawyer about past claims. Then he or she can deal with it. Your lawyer should not be the last one to know!
You can also wreck your Newfoundland and Labrador accident and injury case by going on Facebook or other social networking sites after your accident, and posting words or photographs or videos which are inconsistent with the injuries you say you have. You should not be claiming for a whiplash injury and then be in a video taken at a party dancing up a storm. You can rely on it that the insurance companies and their defence lawyers will find this stuff and use it against you.
The best advice to accident victims about Facebook and social networking is: don't use them!
