The right size law firm with the right lawyers

Nelligan O'Brien Payne LLP is not your average law firm. Ottawa lawyers John Nelligan and Denis Power who founded the firm, formerly Nelligan Power, in 1963, are considered amongst the top lawyers in Canada. Since then, we've grown our firm from our original two founding partners to a team of over 60 lawyers and over 100 business and support staff available to provide services to you in both official languages in a variety of areas of law. We retain our talent by hosting an excellent articling program, supporting a positive and collaborative work environment, and by offering rewarding careers to our talented lawyers and staff.

As a mid-size law firm based in Ottawa, we're the right size to deliver focused, individualized expertise, while offering a broad range of value-added legal and advisory services. Whether you are an individual or large national organization in Canada, we will provide you with exceptional legal advice and guidance at competitive pricing.
