Main Reasons for Divorce in Asia

Marriage remains an important institution across Asia, but the reasons couples decide to end their relationships vary considerably from one country to another. According to the OECD’s Society at a Glance: Asia/Pacific 2025, divorce patterns reflect different legal systems, cultural values, and social expectations.

While every relationship is unique, the most commonly cited grounds for divorce in several Asian countries highlight recurring challenges that many couples face. The report also notes that divorce rates have generally increased across much of the Asia-Pacific region since 2005, although trends differ by country.

In Indonesia, the most frequently reported reason for divorce is constant arguments, suggesting that ongoing conflict and unresolved disagreements can gradually erode a marriage.

In Singapore, unreasonable behavior is the leading cause, reflecting cases where one spouse’s conduct makes it difficult for the relationship to continue. Malaysia identifies personality differences as the primary reason, emphasizing how incompatible values, habits, or expectations can create lasting tension.

Elsewhere in Southeast Asia, Thailand reports infidelity as the most common ground for divorce, demonstrating the serious impact that broken trust can have on a marriage.

In the Philippines, where divorce is generally unavailable for most couples, psychological incapacity is the principal legal basis for ending a marriage through annulment or a declaration of nullity. Vietnam most commonly cites domestic violence, underscoring the importance of protecting individuals from abusive relationships.

In East Asia, Japan and South Korea both identify personality differences as the leading reason for divorce. These cases often involve couples growing apart over time or finding it increasingly difficult to reconcile different lifestyles and expectations.

In China, the most common reason is relationship breakdown, a broad category that reflects the irreversible deterioration of the marital relationship.

In South Asia, India most commonly records cruelty as the reason for divorce. This legal ground may include physical or mental abuse that makes continued cohabitation unreasonable.

Although these reasons differ across countries, they share common themes: communication problems, incompatibility, betrayal, abuse, and the gradual breakdown of relationships.

The OECD findings illustrate that divorce is rarely the result of a single event. Instead, it often reflects long-term issues shaped by personal circumstances as well as each country's legal and cultural framework.
