The 12-month separation rule: when can I file?

You can file for divorce once you have been separated for at least 12 months. The clock starts on the day one of you decided the marriage was over and told the other or made it clear by your actions — not the day someone moved out, and not the day you "officially" agreed. If you separated on 10 January 2025, for example, you can file from 11 January 2026. Our calculator works it out for you. Calculator

What "separated" means

Separation is when at least one of you regards the marriage as over, communicates that (in words or by conduct), and acts on it — living separate lives even if not in separate homes. It doesn't need to be mutual, in writing, or registered anywhere.

When the clock starts

On the date of separation as you'll state it in the application. If your ex disputes the date, the Court may want evidence. Because it matters, note it somewhere now — a message, a diary entry, a change in living arrangements — and be consistent.

Living in the same house

You can be separated under one roof. The Court will want a short affidavit from you and from a witness explaining how life changed (sleeping arrangements, finances, household tasks, social life, telling family). We prepare these; the work is quoted in writing and agreed before any work starts. Separated under one roof

If you got back together

A reconciliation of less than three months in total doesn't restart the clock — the two periods of separation are added together. A reconciliation of three months or more does restart it.

Filing too early

If you file before the 12 months have passed, the application will be refused and the court fee isn't refunded. This is one of the most common DIY mistakes; we check the date against your filing date, not your intake date.
