Which term refers to the legal dissolution of a marital relationship for reasons other than death?

The term that accurately refers to the legal dissolution of a marital relationship for reasons other than death is divorce. Divorce is a formal and legal process through which a marriage is terminated, allowing both parties to legally cease being married and to resolve issues such as asset division and child custody.

Separation signifies a couple living apart while still being legally married, which does not equate to a legal dissolution of the marital relationship. Annulment refers to a legal procedure that declares a marriage null and void, essentially stating that the marriage was never legally valid. Marital breakdown is a more general term that describes a situation where the marital relationship deteriorates but does not specifically indicate a legal process for dissolution. Therefore, the appropriate and precise term that captures the legal dissolution of marriage is divorce.
