What is an "irretrievable breakdown"?

An irretrievable breakdown sometimes called an "irremediable breakdown" is when the couple cannot live together at all, usually because one spouse has moved out of the marital home and/or refuses to work toward any sort of reconciliation. Judges usually don’t ask what the irretrievable breakdown is, being satisfied with the claim itself. Once again, an experienced lawyer knows if a particular judge is in the habit of inquiring into the breakdown.
