Abstract
This paper examines determination of interests in residential tenancy (‘RT’) agreements on grounds of family violence (FV) in Western Australia (WA). Principles of procedural fairness, contractual certainty, joint and several liability, and vicarious liability were altered when the provisions allowing for determination of interest in an RT on grounds of FV were amended. The alteration of these principles causes detriment for lessors and co-tenants, and the provisions may be misused by perpetrators and cause further harm to victims. A comparative method has been adopted to examine similar provisions found in Alberta, Canada, which prima facie offers a better balancing of the needs of FV victims with the rights and interests of co-tenants and lessors. While the detriment caused to lessors and co-tenants, and the potential for further harm to be caused to victims cannot likely be entirely mitigated, the paper proposes for a better balance of the needs, rights and interests of parties to RT agreements in Western Australia.
