One issue that is increasingly being seen by family solicitors during divorce is one spouse accessing the other’s private emails or online accounts. This can range from knowing a password because it was shared during the marriage, to more deliberate unauthorised access through devices or saved logins.

The law treats digital privacy and unauthorised access seriously, and the consequences can spill over into both civil and criminal territory as well as family proceedings.

How does unauthorised email access typically happen?

In many relationships, digital access is shared with little thought, and it is common for partners to know each other’s passwords, use shared devices, or remain logged into accounts on tablets, laptops, or phones. During separation, this informal access sometimes continues out of habit or convenience.

Common scenarios include:

  • A spouse using a shared laptop where email accounts remain logged in
  • Knowing or guessing a password that was previously shared
  • Accessing cloud backups or synced devices (such as iPads or secondary phones)
  • Monitoring emails through recovery accounts or saved login credentials
  • In more serious cases, installing spyware or keylogging software

What starts as informal access during a relationship can quickly become unlawful once permission is withdrawn or the relationship ends.

Why does it matter legally?

From a legal standpoint, accessing someone’s email without permission can engage several areas of law, even if the parties are still married but separated.

Potential legal issues include:

  • The Computer Misuse Act 1990, which makes it an offence to access a computer or data without authorisation
  • The Data Protection Act 2018 and UK GDPR principles, where personal data is accessed or processed unlawfully
  • Potential breaches of privacy rights under Article 8 of the European Convention on Human Rights (right to private and family life)

Even though spouses often share aspects of life, there is no automatic legal right to access a partner’s private communications. Importantly, separation usually marks the point where implied consent to access ends. Once one spouse changes passwords or makes it clear access is no longer permitted, continued access becomes significantly harder to justify.

Does it affect divorce proceedings?

In family law proceedings, particularly financial remedy cases, conduct is only considered in limited circumstances. The court’s primary focus is fairness and financial disclosure, not punishing wrongdoing.

However, if one spouse obtains emails or private communications, it can still become relevant in a number of ways:

  • It may influence negotiations between the parties
  • It could lead to allegations of improper behaviour or breach of privacy
  • In rare cases, it may affect how the court views conduct if it is extreme or linked to coercive behaviour

Is proof required, and what does that look like?

If one spouse alleges that the other has accessed their emails, evidence becomes important. This might include:

  • Login notifications or security alerts from email providers
  • IP address logs showing unfamiliar access locations
  • Screenshots showing messages being read or deleted unexpectedly
  • Evidence that passwords were changed or accounts were interfered with
  • Expert digital forensic reports in more serious disputes

In practice, however, many cases never reach a technical level of investigation unless there is a wider allegation of misconduct, coercive control, or financial manipulation.

Should you allow continued access to gather proof?

Some spouses consider leaving access open temporarily in order to monitor what the other party is doing or to gather evidence of wrongdoing. Once you know your accounts are being accessed without permission, deliberately allowing it to continue could:

  • Compromise your own position by appearing to condone the access
  • Potentially raise further data protection or privacy issues
  • Escalate conflict and lead to further misuse of personal information
  • Risk creating ongoing harm rather than resolving the issue

Instead, the safer approach is usually to:

  • Change passwords immediately
  • Enable two-factor authentication
  • Secure all connected devices
  • Keep a record of any suspected unauthorised access
  • Seek legal advice if sensitive information has been accessed

From a litigation perspective, courts are generally more sympathetic to a party who takes reasonable steps to protect their privacy once they become aware of a breach.

What if the other spouse gains an advantage from the information?

One of the most pressing concerns in divorce proceedings is the possibility that improperly accessed emails could give one spouse an unfair advantage over the other. This might arise where private communications reveal matters that were never intended to be shared, such as the existence of hidden financial assets or confidential discussions with solicitors about legal strategy.

The conduct of the spouse who accessed the emails may come under criticism, particularly if the court considers that there has been a clear breach of privacy or an abuse of trust. In more serious situations, especially where the behaviour forms part of a wider pattern of intrusion, intimidation, or controlling conduct, the court may take a more critical view and could draw adverse inferences about that party’s behaviour and credibility.

That said, it is relatively rare for the outcome of a divorce or financial settlement to turn solely on evidence obtained through improperly accessed emails. While such material may influence the dynamics of the case or affect how the parties are perceived, the court is generally focused on reaching a fair and proportionate resolution based on the broader picture of financial disclosure and overall conduct.

Can this amount to coercive control?

In some cases, accessing a spouse’s emails can form part of a broader pattern of controlling or coercive behaviour. The family and criminal courts increasingly recognise non-physical abuse, which can include:

  • Monitoring communications without consent
  • Restricting access to devices or accounts
  • Using digital surveillance to intimidate or control
  • Repeated intrusion into private correspondence

If email access is part of this wider pattern, it can become highly relevant in both divorce proceedings and any associated safeguarding issues, particularly where children are involved.

While the family court may not always focus heavily on how evidence was obtained, unauthorised access can still have serious legal consequences and may influence the tone and direction of a case.

The safest and most effective approach is almost always to secure accounts immediately, document concerns properly, and deal with the issue through formal legal channels.
