About MacDonald & Partners LLP
MacDonald & Partners LLP is a Toronto law firm that practices exclusively in family law from an office at 155 University Avenue in the city's financial district. It traces its roots to MacDonald and Ferrier, a firm its own website describes as the first in Canada devoted solely to family law. Its founder, James C. MacDonald, persuaded the Canadian Bar Association to create a dedicated family law section in 1967 and co-wrote Canadian Divorce Law and Practice, published in 1969. In 1992, MacDonald founded the firm that became MacDonald & Partners LLP.
The firm today has nine partners, one counsel, and a number of associates and students, and it handles divorce and separation, custody and access, property division, domestic contracts, and international child custody and abduction cases under the Hague Convention. Its lawyers work through negotiation, mediation, arbitration, and collaborative practice, and take a matter to litigation when that route suits a client better. According to its contact page, the firm's team speaks English, French, Mandarin, Hebrew, Lebanese, Farsi, Japanese, Portuguese, and Slovak.
