This document discusses modern family structures in the UK and the lack of legal protections for cohabitating couples. It summarizes a landmark 1983 court case, Burns v Burns, where a woman who lived with a man for 18 years was denied any rights or share of the family home upon separation. While married couples have protections upon divorce, cohabitating couples do not, which can lead to financial hardship. Various approaches to address this issue, such as contractual agreements, restitution claims, or adopting rules similar to Sweden that provide an equal division of jointly owned family property, are discussed. The document argues for legislative reforms to provide greater protections for cohabitating parents and their children.
