In contemporary Japan, an uncommon but increasingly notable trend has arisen where divorced couples continue to cohabit, often due to financial constraints or child custody issues. This article examines the potential legal risks and implications that are associated with such living arrangements, which is gaining relevance amidst rapidly changing social norms and family structures. Legal experts warn of the complexities and potential predicaments faced by such couples, urging a careful understanding of respective rights and obligations.

In Japan, the concept of divorced couples living together is not traditionally common, but it's seeing a surge due to financial hurdles and the best interest of the child. The Japanese value harmony in their families and society, and this extends to how they handle divorce and its aftermath. Hence, such cohabitation is explored as an option wherein both parties maintain harmony while allowing easier facilitation of child-rearing and shared responsibilities.

In the US or EU, there is a broader acceptance of varied family structures, including those of divorced parents. Co-habitation after divorce, while not the norm, is a choice made for similar reasons such as collective parenting and economic factors. However, this presents a range of legal issues, from property rights to tax implications.
