What you are actually confirming

That, in your view, the marriage has broken down and there is no realistic prospect of reconciliation. You do not explain how or why, and you do not attach evidence.

How it fits into the timetable

  • The application is issued with the statement of irretrievable breakdown
  • 20 weeks of reflection follow
  • You then confirm you wish to continue and apply for the Conditional Order
  • Six weeks and a day later you can apply for the Final Order

Reflection is built in for a reason

The 20-week period exists so couples have time to consider reconciliation or to sort out practical matters such as finances and arrangements for children.

Frequently asked questions

The statement is conclusive evidence of irretrievable breakdown.
