There is no right or wrong answer here. However, if you are married, there are some legal considerations for you if your partner has an affair. So, here is what you need to do if you find out your spouse has/is having an affair. “Shocked, betrayed and confused are just some of the emotions that we see clients dealing with when their relationship has broken down due to an affair.

In the beginning, we advise them to take some time to consider the next steps rather than lashing out in an act of retaliation which they may later regret.

Once the dust has settled, communication is crucial, whether you want to try and save the relationship or have decided it is over and need to plan a way forward.

Staying Together

Relationship counselling can be extremely helpful in supporting couples to open-up, explore the problems between them and get back on track. There are many counselling services available.


If there is no way back following an affair, then we would recommend taking early advice on the divorce process. In English law, there is only one ground to petition for divorce and that is that the marriage has irretrievably broken down. Although there has been a lot in the news about the new era of ‘no-fault divorce’, it is likely to take some time for parliament to ratify the necessary legislation. So for now, to prove this, you must currently rely on one of 5 facts and one of these is adultery.

Specifically, the law states that you can petition for a divorce based on adultery if your spouse has committed adultery and you find it intolerable to live with them. Importantly, however, same-sex spouses cannot use this fact to prove irretrievable breakdown (and would instead need to allege ‘unreasonable behaviour’). Importantly, adultery can be committed and used for a reason to divorce, even after a married couple has separated.

Even if adultery is applicable, it isn’t necessarily that straight forward. What the court recognises as adultery and what you consider to be an affair are not always the same thing.

The Law Relating To Adultery

The court considers adultery to be the voluntary intercourse between a man and a woman. A close relationship which you may consider inappropriate, involving meetings, messages, emails (but without actually having sex with that person) is not recognised legally as adultery.

However, whilst the court would not recognise it as adultery, such behaviour can be used as an example of unreasonable behaviour and a divorce petition can be presented on this basis instead, as it can with same-sex spouses who discover their spouse is conducting a relationship with a third party.

It should also be pointed out that if you continue to live with your spouse for a period of 6 months or more after you found out about the adultery then you cannot use that adultery as the basis for a divorce petition unless that adultery is continuing. If so, the 6-month period begins to run from the last adulterous incident. If, however, it was a ‘one-off’ which took place more than 6 months before you found out, or your spouse denies having committed adultery, your safer option is to proceed on the basis of their behaviour.

Getting Divorced

Citing adultery in a divorce petition requires the spouse to admit to the adultery in the paperwork. From a practical point of view, it is worthwhile asking their spouse to sign a statement confirming their agreement before proceedings are issued. In the long-run, this will help reduce the risk of costly defended divorce proceedings. Again, if your spouse is unwilling to sign a statement, you should consider presenting your petition on the basis of unreasonable behaviour.

If you continue with the adultery petition and the divorce is defended it is the court that will decide whether there is evidence to show that the adultery has been committed, and let’s face it, short of hiring a private investigator (which can be done) it is unlikely that you will have any direct evidence of the adultery. However, if there is enough circumstantial evidence to show opportunity and an inclination to commit adultery, the court should be able to draw inferences that the adultery has been proved and the petition can proceed on that basis.
