This report was created in order to aid the reform of the matrimonial and child support system in Alberta. Before its publication, there was little data regarding the reasons for failure in the (then) extant system. The report analyzes data from the Supreme Court (now Court of Queen’s Bench) in Edmonton and Calgary, the Family Courts in Edmonton, Calgary, Lethbridge, and Grande Prairie, door-to-door surveys of those involved with maintenance orders, and a study of defaulters. As a result, it presents a rich and varied survey of the reasons why maintenance fails, which could then be used as a basis for reform.
