Japan's Civil Code Reforms Introduce Joint Custody for Divorced Parents
Japan has enacted a landmark revision to its Civil Code, permitting divorced couples to share legal custody of their children for the first time. This significant change, effective from Wednesday, 1 April 2026, marks a departure from the previous requirement of sole custody, which often limited one parent's involvement after divorce.
New Custody Options and Legal Framework
The revised legislation allows couples to mutually agree on either joint or sole custody arrangements. If an agreement cannot be reached, family courts will determine the custody arrangement based on the child's best interests. This shift aims to promote more balanced parental involvement and reduce conflicts in post-divorce family dynamics.
Parents who divorced under the old rules are now eligible to apply to a family court to seek a change to their custody arrangements. This provision enables them to potentially transition to a joint custody model, offering greater flexibility and cooperation in raising their children.
Prioritising the Child's Best Interests
The new law emphasises the child's welfare as a primary concern. In joint custody cases, both parents must agree on major decisions affecting the child, such as education, healthcare, and religious upbringing. However, the legislation allows for independent decisions on daily or urgent matters, ensuring practicality in day-to-day parenting.
Financial Provisions and Child Support
A key component of the reform is the introduction of a financial provision to support children in divorced families. The law establishes a monthly payment of 20,000 yen per child for the parent living with the child, applicable to divorces finalised from 1 April 2026. Additionally, child support claims are given priority over other debts, enhancing financial security for children.
This reform reflects a broader trend towards modernising family law in Japan, aligning with practices in many Western countries. It is expected to reduce legal disputes and improve outcomes for children by fostering ongoing relationships with both parents after divorce.
