Grounds for Divorce in Scotland

Scotland has one legal ground for divorce: irretrievable breakdown of the marriage. But you prove that breakdown through one of four specific facts, and which one you choose determines your procedural track, your timeline, and how much evidence you need.

The Four Facts

1. One Year's Separation with Consent

You and your spouse have lived apart for at least one continuous year, and your spouse signs a written consent form agreeing to the divorce. This is the most commonly used ground and the cheapest route — it qualifies for the Simplified Procedure (Form CP1), which costs £156 and takes 6–10 weeks after filing.

2. Two Years' Separation Without Consent

You've lived apart for at least two continuous years. Your spouse's agreement is not required — you can proceed even if they refuse to engage. This also qualifies for the Simplified Procedure (Form CP2), though the longer separation period means a later start.

3. Adultery

Your spouse has committed adultery with another person. There is no separation period required, but you need corroborating evidence — typically a sworn statement from a witness or documentary proof.

Adultery can only be used under the Ordinary Procedure, which costs more (£191 filing fee), takes longer (12–16 weeks minimum), and requires you to draft an Initial Writ rather than filling in a standard form.

4. Unreasonable Behaviour

Your spouse has behaved in a way that no reasonable person could be expected to continue living with. This is subjective and requires detailed written examples plus a corroborating witness affidavit.

Like adultery, this ground is only available under the Ordinary Procedure. The behaviour must be sufficiently serious — courts look for patterns, not isolated incidents.

Which Ground to Choose

For most people, 1-year separation with consent is the clear best option. It's the cheapest, fastest, and requires the least evidence. The only reason to choose a fault-based ground is if you need to divorce before the separation period is up — and even then, the ordinary procedure's added complexity and cost often negate the time saved.

The Reconciliation Rule

Scotland allows you to attempt a reconciliation during the separation period without permanently resetting the clock. You can live together again for up to six months total — but those days don't count toward your separation period. They're deducted.

If you separate for 13 months but spend 2 of those months trying to reconcile, your legal separation is only 11 months. You'd need to wait 3 more months before you qualify for the 1-year ground.

If your total reconciliation time exceeds six months continuously, the entire separation period resets to zero.

Separation Under the Same Roof

You don't have to physically move out to start the separation clock. Scottish courts recognise separation under the same roof if you can show you're living as two separate households — sleeping apart, eating separately, splitting bills independently, and no longer presenting yourselves socially as a couple.

For ordinary procedure divorces, you'll need a third-party witness to confirm this arrangement.

What About "No-Fault Divorce"?

England and Wales introduced no-fault divorce in April 2022, removing the need to prove any specific ground. Scotland hasn't adopted this reform. You still need to establish one of the four facts above. The Scottish Government has consulted on family law changes, but no equivalent legislation has been passed.
