Unreasonable behaviour divorce

Written by CalmSplit Editorial TeamReviewed by Ramani GillLast reviewed 13 August 2026England & Wales

You no longer need to set out examples of unreasonable behaviour. That requirement disappeared with the no-fault reforms, so nobody has to write allegations about their spouse to obtain a divorce.

CalmSplit prepares a no-fault divorce application for a one-off £159, with no behaviour statement to draft and nothing to prove.

  • Behaviour allegations were removed from the process
  • Less conflict, and nothing for a spouse to dispute
  • Applications can be joint or sole

Why the old requirement was removed

Requiring one spouse to blame the other created unnecessary conflict, particularly where children were involved. The reformed law replaced it with a single statement of irretrievable breakdown.

What the application looks like now

  • Details of both spouses and the marriage
  • A statement that the marriage has broken down irretrievably
  • Choice of sole or joint application
  • Optional applications about finances, made separately

If there has been abusive behaviour

The divorce process itself does not deal with safety. If you are at risk, seek support and advice about protective options before starting. CalmSplit is not suitable for urgent safety situations.

Frequently asked questions

No. No particulars or evidence are required.
