"Personality incompatibility" is the term commonly used in English to describe the reason for divorce when it is attributed to differences in personality. This phrase is often used in legal and social contexts to explain that the couple's personalities are not compatible, leading to difficulties in maintaining a harmonious relationship. It is a broad term that can encompass a variety of specific issues, such as different communication styles, conflicting values, or incompatible life goals. In legal documents, it may be listed as one of the grounds for divorce, especially in jurisdictions where no-fault divorce is recognized.
