Thomson on "And Two Cows...to My Wife, So Long As She Remains My Widow": Public Policy and Testamentary Marriage Clauses in Canada

Jane Thomson, University of New Brunswick Faculty of Law, is publishing "And Two Cows to my Wife… so Long as she Remains my Widow." Public Policy and Testamentary Marriage Clauses in Canada in volume 103 of the Canadian Bar Review. Here is the abstract.
This article, part one of a two part project, provides a comprehensive review of the law surrounding marriage conditions in wills in Canada, including the civil law jurisdiction of Quebec, through a quantitative study of nearly every electronically reported Canadian decision involving a marriage clause in a will. It begins with an overview of the history of marriage clauses in the UK, the US and Canada with a detailed review of the Canadian jurisprudence. This study reveals that the application of public policy to most marriage clauses in Canadian wills has remained stagnant since the 18 th century, with two notable exceptions. The first involves clauses that condition a gift on discriminatory terms such as the sex, race or religion of a beneficiary's spouse. When asked to do so, Canadian courts have voided such conditions, beginning in the 1960s. The second is the Province of Quebec where arguably all marriage clauses are now contrary to public order. This article is followed by a companion piece that provides the normative argument as to why all marriage clauses should be considered contrary to public policy in Canada.
