UK The old meaning, which no longer applies
For most of the last fifty years, getting divorced in England and Wales meant proving one of five facts: adultery, unreasonable behaviour, desertion, two years' separation with consent, or five years' separation. A spouse who rejected the allegation could defend the petition, and the court would decide whether the fact had been proved.
That is where the phrase 'contested divorce' comes from. It described a trial about whether the marriage had broken down and whose fault it was — an expensive, slow and often bitter exercise that decided nothing about money or children.
What changed on 6 April 2022
The Divorce, Dissolution and Separation Act 2020 replaced the five facts with a single statement that the marriage has broken down irretrievably. The court must accept that statement unless one of a very short list of technical points is raised.
In practical terms, the divorce itself is no longer something the other person can fight. That removed the single largest source of delay and hostility from the early stages, and it also removed a piece of leverage: one spouse can no longer refuse to divorce, or threaten to embarrass the other, in order to win concessions elsewhere.
The same framework applies to the dissolution of a civil partnership, and it applies in England and Wales only. Scotland and Northern Ireland kept their own law.
So what is a contested divorce now?
Almost always a dispute about money or children rather than about the divorce. Those are separate legal proceedings that run alongside the divorce, and they are where the argument, the cost and the delay actually live.
This matters because the two can finish at different times. A divorce can be completed, and the marriage ended, while the financial claims are still being negotiated. Many solicitors advise against applying for the final order before the finances are settled, because ending the marriage can affect pension rights and some claims — see our guide to consent orders and clean breaks.
'Uncontested' does not mean 'agreed'
An uncontested divorce usually just means nobody has raised a technical objection. It covers the couple who have agreed everything, and it also covers the far more common case where the other person simply does not respond at all.
A failure to respond is not agreement, but it does not stop the divorce. Where a respondent does not file an acknowledgement of service within the time allowed, the applicant can normally still apply for the conditional order. If you cannot establish where your spouse is, or service is difficult, that is a procedural problem with solutions — it is not a reason the divorce cannot happen.
The rare cases that are genuinely defended
A divorce can still be opposed in England and Wales, but only on narrow grounds. The challenged points are essentially these: that the court has no jurisdiction to deal with the case, that the marriage is not valid, or that the marriage has already legally ended. The Judiciary of England and Wales publishes the current guidance on this and on the procedure for a dispute about the divorce itself.
These cases are unusual, and they are expensive per day of hearing because they usually need a barrister as well as a solicitor. If your spouse is threatening to 'contest the divorce', it is worth checking which of those narrow grounds they could actually be relying on. A threat to defend the finances is a different thing entirely, and much more common.
Scotland and Northern Ireland
Scotland did not adopt the 2022 reforms. A divorce there is still granted on irretrievable breakdown established by one year's separation with consent, two years' separation without consent, unreasonable behaviour or adultery. Because a ground must be established, an action can in principle be defended, and the expenses consequences of doing so fall on the party who loses. Our guide to divorce in Scotland sets out the framework.
Northern Ireland also retained fault-based grounds, and the two-year marriage bar means no petition can be presented in the first two years at all. Where a petition is defended there, the case is heard in the High Court rather than the County Court — nidirect sets out the procedure and the current court fees. See also our guide to divorce in Northern Ireland.
How to keep the divorce itself uncontested
Keep the divorce and the argument in separate boxes. Nothing is gained by disputing the paperwork, and everything you spend fighting about the wording of an application is money not available to settle the things that matter.
Deal with the acknowledgement of service promptly if you are the respondent — delays there only slow down a process that is going to conclude anyway. Use the waiting periods deliberately: the roughly six-month minimum in England and Wales is the window in which the financial disclosure should be getting done, not a pause to be endured. And keep communication in writing, through solicitors if direct contact is difficult, because everything in these proceedings eventually has to be evidenced.
