 I was amazed by how fast the team got involved

Client Reviews

Transparent and straightforward

“This is hands down the best law firm I ever worked with. I worked with Erin and she was amazing from the beginning. We received a cease-and-desist letter in regards to a trademark issue, and Erin and her team were able to guide me through the whole process. They went over the letter and its merits and guided me in responding to this letter and resolving the matter. They also trademarked a few names for us for both Canada and USA. It was so easy dealing with them, all my questions were answered promptly and Erin is so attentive to details and extremely knowledgeable about the law. What I particularly enjoyed about using their services is how transparent and straightforward they are with their pricing. If they can’t give an exact price immediately, they will at least give an estimate or a price range. There are never any negative surprises working with them. They have proven time and time again that there is no one else I’d rather turn to for legal help.” – Sam

Great service and good value

“I had a great professional experience with Wing T Yan, a lawyer at Nelligan Law. After filling a trademark on my behalf, she and members of her staff were responsive as they generously provided all related info to register my screenplay copyrights with Industry Canada and the Library of Congress. Should I require additional assistance, I feel that I shall obtain great support. I recommend this legal group to anyone who wants great service and good value for their money.
