This third edition is updated and features new chapters on the Child Support Act and the new law on domestic violence and homelessness. It offers new material on increasingly important issues such as negative equity, transfer of tenancies, domestic violence, homelessness, cohabitation contracts, child support assessments. Valuable precedents are also provided, including a framework cohabitation agreement and a declaration of trust for co-owners of freehold property. The text is divided into two parts, dealing firstly with ongoing relationships and then with relationship breakdown.
