The first question most separating spouses ask a solicitor is some version of “what do I have to prove?” The answer in Scotland is simpler than most people expect. There is a single ground for divorce — that the marriage has broken down irretrievably — and four recognised ways of establishing it, set out in the Divorce (Scotland) Act 1976 as reformed in 2006.
This article answers the questions we hear most about the four routes: how long each takes, when you need your spouse’s consent, whether “fault” changes the money or the children, and which route the simplified procedure allows.
What are the four ways to establish irretrievable breakdown?
Under Scots law, irretrievable breakdown is established by any one of:
- One year’s non-cohabitation plus your spouse’s consent to the divorce;
- Two years’ non-cohabitation, with no consent required;
- Unreasonable behaviour — behaviour such that you cannot reasonably be expected to continue living with your spouse;
- Adultery.
Separately, an interim gender recognition certificate issued to either spouse is also a ground. The old ground of desertion was abolished in 2006.
Which route is quickest?
If you’re already separated, the calendar answer is the one-year route with consent — and for couples with no children under 16 and no financial claims, it unlocks the inexpensive simplified procedure. If you cannot wait a year — or your spouse won’t consent and two years feels impossible — behaviour is the usual faster route, because it can be raised immediately. In practice, most Scottish divorces proceed on the no-fault separation routes: solicitors typically resolve finances by Minute of Agreement during the separation period, then divorce quietly on the one- or two-year ground.
What counts as “unreasonable behaviour”?
The test is whether your spouse has behaved in such a way that you cannot reasonably be expected to continue living together. Courts have accepted a wide spectrum: violence and abuse at one end; persistent drinking, financial recklessness, controlling conduct, or sustained emotional neglect in the middle; and accumulations of smaller conduct at the other. The behaviour is set out in the writ in factual terms — competent drafting states enough to found the ground without inflaming matters, since in undefended cases your spouse never needs to admit anything, only to not contest it.
How does the adultery route work?
Adultery means voluntary sexual intercourse between your spouse and another person of the opposite sex — a definition that predates modern relationships, which is why conduct outside it (including a spouse’s same-sex affair) is instead founded on as behaviour. Proof in contested cases is by inference from evidence; in reality, most adultery-based divorces proceed undefended. You do not need to name the third party, and solicitors usually advise against it.
Does “separated” require two addresses?
No. Non-cohabitation means you have ceased living together as husband and wife, and Scottish courts accept separation under one roof — separate rooms, separate finances, separate domestic lives — which matters when housing costs trap separated couples together. Keep evidence of when the separation began: the date fixes both the divorce clock and, crucially, the “relevant date” at which matrimonial property is valued. Brief attempts at reconciliation (up to six months in total) don’t restart the separation clock, though they don’t count towards it either.
Will proving fault get me a better financial settlement?
Almost never — and this is the most expensive misconception in Scottish divorce. Under the Family Law (Scotland) Act 1985, conduct is ignored in dividing matrimonial property unless it has adversely affected the finances (gambling away savings, destroying assets) or it would be manifestly inequitable to leave it out of account — a deliberately high bar. An affair, however painful, does not shift the split. Money spent proving blame is usually money burned.
Does the ground affect the children?
No. Arrangements for children are governed by their welfare under the Children (Scotland) Act 1995, decided on present circumstances rather than on which spouse’s conduct ended the marriage. A parent’s behaviour matters only insofar as it bears on the children’s welfare — abuse obviously does; an affair, by itself, does not. See our guide to contact and residence.
My spouse won’t consent — am I stuck?
Only for the one-year route, which is the sole ground requiring their agreement. After two years’ separation you need nothing from them; and behaviour or adultery, if available on the facts, need proof rather than permission. A spouse who simply ignores the proceedings does not stop them — undefended decrees are granted in their absence. We’ve written a full guide to dealing with a spouse who won’t engage.
Where do I actually raise the divorce?
Almost always in your local sheriff court — the Court of Session in Edinburgh is reserved for a small minority of complex or high-value cases. Which sheriff court serves you depends on where you live: our location guides name the court for each area — for example Glasgow, Edinburgh, or the town-by-town court lists in our regional guides such as Lanarkshire and Ayrshire — and rank the local solicitors who appear there every week.
