Marta Siemiarczuk is a partner and the head of the Family Law Group at Nelligan O’Brien Payne. Marta practices in the areas of Family Law Litigation and Collaborative Family Law and is also a Family Arbitrator.

Prior to joining the firm, Marta was with a large national firm in Ottawa, where she practiced in civil litigation and family law until 2008. In 2009 Marta focused exclusively in the area of family law in a boutique firm in London, Ontario, where she also sat on the Executives of the Middlesex Family Law Association and the Collaborative Lawyers of London and Middlesex.

Marta has acted as a co-instructor at the University of Ottawa, Faculty of Law, for Civil Procedure and the Alternative Dispute Resolution Program. She is a regular guest lecturer at the University of Ottawa in Family Law. She is also a regular columnist on various family law topics for the Law Times.

Marta approaches her work in a client-centered manner, always striving to be efficient and to provide practical and creative solutions. She derives great satisfaction in practicing family law, as it allows her to be involved in a tangible way with her clients, able to make meaningful differences to their lives. And while she is dedicated and very driven, she also maintains a good sense of humour.

The focus of her days outside of the office is her family, who motivate Marta to maintain a healthy perspective. Weekends find her either tinkering with renovations around the home, playing with her kids, or getting outdoors to go camping, hiking or canoeing.
