You believe your partner is unfaithful, and you want to get a divorce. But that’s easier said than done in the United Kingdom. Before you can part ways, you have to prove that adultery was committed in the first place.

What is Adultery?

In the UK, adultery is present if a married man has sex with a woman other than his wife; or if a married woman has sex with a man other than her husband.

While some people confuse one for the other, adultery and infidelity are two different things under English law. Adultery refers to sexual intercourse between a man and woman when they are married to someone else.

Infidelity has another meaning. Here, sexual intercourse is not always involved, but it includes physical and emotional acts disloyal or unfaithful to your partner. These include kissing, dating or any behaviour which is not right in a committed relationship or marriage.

Is Adultery a Crime in The UK?

No, it’s not, but it is one of the reasons for getting a divorce. That may sound simple, but adultery can be difficult to prove because of the following reasons.

First, adultery can only be cited as grounds for divorce if your partner has had sex with a person of the opposite sex. If your partner had a relationship with someone of the same sex, that’s not adultery under UK law. This means you can’t use this as a reason for getting a divorce.

In the same way, adultery is not present if your partner is in a homosexual relationship or has a same-sex extramarital affair.

To complicate things, you must prove that your marriage has broken down before you can get a divorce. Aside from adultery, there are four grounds for divorce:

  • Unreasonable behaviour – your partner behaves in such a way that you can’t live with that person any longer.
  • Desertion – your partner has deserted you for a continuous period of two years before you file for a divorce.
  • Two years of separation with consent – you and your partner have been separated for at least two years.
  • Five years of separation – both you and your partner have lived apart for a continuous period of five years.

Contrary to popular belief, the use of online dating apps or sites does not constitute adultery. While intimacy may be present when communicating with other people using these apps, that alone doesn’t justify divorce. As explained earlier, there have to be sexual relations with a person of the opposite sex.

Also, you can’t get a divorce if you continue to live together with your partner. There must be a period of separation for six months or more after you learn that your partner has been unfaithful. If you still live together, you can’t use adultery as an excuse for divorce.

For these reasons, divorce due to adultery is less common than you think. If they believe their partner has been unfaithful, most people cite “unreasonable behaviour” instead.

There are various reasons for getting a divorce, but one thing is clear: it can greatly affect your life and strain your relationship. Therefore, it’s important to get expert legal advice.
