We have relied on David’s expertise twice now, the first time in a complex fraud case and recently in a partnership dispute.  We have been extremely satisfied with the extensive knowledge, attention to detail and service that David and his teams have provided.  In the land development business we have had the occasion to use many lawyers over the past 50 years and give David Debenham our highest recommendation.

I would like to recommend David Debenham.  We worked together on the Base Finance Ponzi scheme which is considered to be one of Canada’ largest schemes, defrauding over 240 investors of over $125million that operated for decades. Mr. Debenham’s advice resulted in continued favorable court decisions. If you want to win on a fraud case, Mr. Debenham should be on your legal team.

We have been dealing with Mr. Debenham for many years on various subjects. He has helped us navigate through everything, all while being straight to the point with no sugar coating. On that note though, he cares about his clients and all the tips and information provided is always to teach you the proper way to follow your rights to make sure to protect yourself, and your business in the future. Dealing with him will not only relieve stress while going through a matter but also be very informative. We highly recommend Mr. Debenham for any business owner.

David’s tremendous attention to the finer points of the law and his comprehensive knowledge of construction law, specifically, served the company well in all of our pleadings and various activities.

The approach that Mr. Debenham took was always very practical and with providing NLG with “best in class” advice, while exercising a practical approach to each and every file. His desire to provide value in each and every instance did not go unnoticed, as he constantly reminded us of cost-effective approaches, to achieving the best results.

David Debenham is a top-notch litigator and client advocate. He helped our family navigate a ‘challenging’ real-estate situation. He was the David to their Goliath, but instead of slaying the giant he had the builder fulfill their contractual obligations. We cannot thank him enough for his sage advice, direct communication style, and help. We recommend him to anyone facing potential issues with their builder and/or Tarion.
