No-fault divorce is divorce in which the dissolution of a marriage does not require fault of either party to be shown, or, indeed, any evidentiary proceedings at all. It occurs on petition to the
court, typically a
family court by either party, without the requirement that the petitioner show
fault on the part of the other party. Either party may request, and receive, the dissolution of the marriage, despite the objections of the other party.

A divorce in which it it doesn't matter who did what to whom that caused the marriage to break down; all that matters is that there is no reasonable prospect of reconciliation.
