Understanding the legal grounds for divorce can help you make clear decisions at a point when your personal, financial and family circumstances may already be changing.

For many years, divorce law in England and Wales placed separating couples in a difficult position. Even where both parties accepted that the marriage was over, the legal process often required one spouse to rely on blame or wait for a period of separation before they could move forward.

That changed with the introduction of no fault divorce in April 2022. The current system is designed to reduce unnecessary conflict at the start of the divorce process, allowing couples to focus more constructively on the decisions that need to be resolved.

Those decisions involve arrangements for children, the family home, business interests, pensions, trusts and the wider financial settlement. Knowing what the law now requires - and what it no longer requires - can help you approach the process with more clarity and control.

In this guide, we explain how the grounds for divorce have changed, what the current legal position means in practice, and the key steps involved in getting divorced in England and Wales.

What Are the Grounds for Divorce in England and Wales?

The legal grounds for divorce in England and Wales are now based on one principle: that the marriage has broken down irretrievably.

This means the court does not need to decide who was responsible for the end of the marriage. You do not need to prove adultery, unreasonable behaviour or any other form of fault. You also do not need your spouse to agree that the relationship has ended before you can apply for divorce.

Instead, the divorce application includes a statement confirming that the marriage has irretrievably broken down. Under the no-fault divorce law, this statement is treated as conclusive. In practical terms, it means the court does not investigate the reasons behind the relationship breakdown before allowing the divorce process to continue.

To begin divorce proceedings, couples need only prove the following:

• They have been married for over a year
• The relationship has permanently broken down
• Their marriage is legally recognised in the UK

This represented a significant change in divorce law. For many couples, it removed the need to start the process with allegations about personal conduct. That can be particularly important where there are children, shared businesses, family wealth or ongoing financial arrangements that need to be handled carefully.

It is still possible for difficult behaviour to matter in a wider family law context. For example, domestic abuse, controlling behaviour or concerns about financial conduct may be relevant to child arrangements, safeguarding, financial disclosure or how negotiations are managed. However, they are no longer needed as legal grounds for divorce itself.

The current no-fault system is intended to reduce conflict at the outset, but it does not remove the need for strategic advice. The legal divorce ends the marriage. Separate decisions may still need to be made about money, property, pensions, business interests, trusts and arrangements for children.

How Did Divorce Work Before April 2022?

Before the introduction of no-fault divorce, the only legal ground for divorce was still the irretrievable breakdown of the marriage. However, one spouse had to prove this by relying on one of five legally recognised facts.

These were commonly referred to as the five grounds for divorce, although technically they were the five ways of proving that the marriage had irretrievably broken down. In practice, this meant that many couples had to begin the divorce process by pointing to fault, even where both accepted that the relationship had come to an end.

The five facts were:

• Adultery: one spouse had an extramarital relationship, and the other spouse found it intolerable to continue living with them.
• Unreasonable behaviour: one spouse behaved in a way that meant the other could not reasonably be expected to continue living with them.
• Desertion: one spouse left the other for a continuous period of at least two years.
• Two years’ separation with consent: the couple had lived apart for at least two years, and both agreed to the divorce.
• Five years’ separation: the couple had lived apart for at least five years, in which case consent from the other spouse was not required.

For many couples, unreasonable behaviour became the most practical route, particularly where they did not want to wait for two or five years of separation. This could include a wide range of issues, from poor communication and emotional distance to substance abuse, financial disputes or other behaviour that had affected the relationship.

The difficulty was that the old fault-based divorce system often encouraged couples to frame the end of the marriage in adversarial terms. One party might have felt forced to make allegations, while the other felt criticised or exposed at the very start of the process. This could make it harder to reduce conflict and avoid protracted legal battles, particularly where children or significant financial arrangements were involved.

In cases involving domestic abuse, the previous system could also create additional pressure. The person applying for divorce might have needed to refer to behaviour that was painful, sensitive or strategically difficult to raise at that stage.

The law surrounding divorce in the UK was changed because the old system no longer reflected how many divorcing couples approached separation in reality. In many cases, the most important question was not who was to blame, but how both people could move forward with clarity, protect their children and resolve financial matters properly.

What Changed Under No-Fault Divorce?

No-fault divorce changed the way divorce in England and Wales could begin. Since April 2022, divorcing couples no longer need to rely on fault, separation or consent to prove that a marriage has ended.

This removed the need to set out allegations of unreasonable behaviour or adultery in order to start the process. It also means one spouse cannot usually prevent the divorce from going ahead simply because they do not agree with the decision to end the marriage.

Under the current no-fault divorce law, couples can apply in one of two ways:

• Sole application: one spouse makes the divorce application.
• Joint application: both spouses apply together, confirming that they both accept the marriage has broken down.

The ability to make a joint application is an important development. It gives many couples a more constructive way to approach divorce, particularly where they want to keep communication open, protect children from avoidable conflict or preserve a workable relationship after separation.

A sole application may still be the right option where one partner is not engaging, there is a difficult power dynamic or it is simply more appropriate for one party to take the lead. This can be especially relevant where there has been domestic abuse, controlling behaviour or a lack of cooperation.

No-fault divorce does not mean every issue is agreed. It only changes the legal basis for ending the marriage. Decisions about children, financial settlement, the family home, pensions, business interests and ongoing support still need to be resolved separately and carefully.

What Are the Benefits of No-Fault Divorce?

No-fault divorce gives separating couples a less confrontational way to start the legal process. This can help reduce conflict early on, particularly where children, shared assets or ongoing financial arrangements need to be dealt with. It also avoids the need to set out allegations of unreasonable behaviour or adultery in the divorce application.

The main benefit is not that divorce becomes “easy”, but that the process begins with less unnecessary friction. This allows more attention to be placed on the issues that shape life after divorce, including child arrangements, housing, pensions, business interests and the financial settlement.

No-fault divorce is therefore a clearer and more constructive starting point. It does not replace the need for careful legal advice, but it can make it easier to approach the next stage with focus and control.

How Does the Divorce Process Work?

The divorce process in England and Wales follows a set legal structure. It deals with the legal end of the marriage, but it does not automatically resolve financial arrangements, child arrangements or what happens to property, pensions or other assets.

Before applying, you should check that you are eligible to divorce. In most cases, this means you have been married for at least a year, your marriage is legally recognised, and the relationship has irretrievably broken down.

The main legal stages are:

• Divorce application: one spouse can make a sole application, or both spouses can make a joint application.
• Acknowledgement of service: in a sole application, the other party is usually asked to confirm that they have received the papers.
• Conditional order: after the 20-week waiting period, the court can confirm that there is no legal reason why the divorce cannot proceed.
• Final order: six weeks and one day after the conditional order, you can usually apply for the final order, which legally ends the marriage.

The minimum time frame for divorce is around six months. However, the wider process can take longer if financial disclosure is incomplete, the other party does not respond, child arrangements are unresolved or there are issues involving business interests, pensions, trusts, property portfolios or international assets.

It is important not to treat divorce as a purely administrative process. The final order ends the marriage, but it does not automatically provide a financial settlement or prevent future financial claims. Where money, property, pensions or maintenance need to be resolved, a financial order or consent order will usually be needed.
