Justipedia explains Irretrievable Breakdown
Irretrievable breakdown is a term that is being used less with the increase of no-fault divorce states. In states where divorcing parties must cite a reason for a divorce, irretrievable breakdown is a blanket term that covers any reason that results in either party being unwilling to continue with the marriage. Only one party must cite irretrievable breakdown for a divorce to be granted. In some states, the point must be proved through elaboration and sometimes confirmation from third-party witnesses.
