Less adversarial approaches to divorce settlements have recently emerged, such as mediation and collaborative divorce settlement, which negotiate mutually acceptable resolution to conflicts.
This principle in the United States is called 'Alternative Dispute Resolution' and has gained popularity.
Divorce should not be confused with annulment, which declares the marriage null and void; with legal separation or de jure separation (a legal process by which a married couple may formalize a de facto separation while remaining legally married) or with de facto separation (a process where the spouses informally stop cohabiting).
Reasons for divorce vary, from sexual incompatibility or lack of independence for one or both spouses to a personality clash.
The Vatican City is an ecclesiastical state, which has no procedure for divorce.
Note that "separation" does not necessarily mean separate residences – in some jurisdictions, living in the same household but leading a separate life (e.g., eating, sleeping, socializing, etc.
separately) is sufficient to constitute de facto separation; this is explicitly stated, e.g., in the family laws of Latvia.
