Divorces can often involve complex emotions, mistrust, and disputes over assets. However, the situation becomes even more complicated when one party suspects that their ex-partner has accessed their personal accounts without permission. Whether it’s email, bank accounts, pensions, or investment portfolios, such access can have legal implications. This article explores what the law says about unauthorised access to personal accounts during divorce, the actions you can take if you suspect it, and whether such behaviour might affect your case, even post-divorce.
Divorces can often involve complex emotions, mistrust, and disputes over assets. However, the situation becomes even more complicated when one party suspects that their ex-partner has accessed their personal accounts without permission.

This article explores what the law says about unauthorised access to personal accounts during divorce, the actions you can take if you suspect it, and whether such behaviour might affect your case, even post-divorce.
Types of accounts and access: understanding the risks
During divorce proceedings, both parties are required to disclose financial information, including bank accounts, pensions, and investments. However, this disclosure is governed by formal processes, and unauthorised access to personal information breaches legal and ethical boundaries. Here are the main types of accounts where unauthorised access may occur, and the specific risks involved:
- Email accounts often hold sensitive information, such as correspondence with solicitors, financial statements, and other key documents. Accessing an ex-partner’s email without permission may compromise the divorce process by revealing privileged information.
- Unauthorised access to bank accounts may give the other party insight into hidden assets or spending patterns. This can undermine financial negotiations or lead to an unfair settlement.
- Divorce settlements often involve pension sharing or offsetting, and gaining unauthorised access to pension accounts or investment portfolios can distort a fair division of assets.
- While these accounts may not directly affect financial settlements, gaining access to private messages or social media activity can be used to undermine an individual’s credibility or even for emotional manipulation.
What are the legal implications of gaining access?
The way in which your ex-partner gained access to your accounts can have legal implications. Common ways might include:
- If your ex knows or guesses your passwords, they might argue that they didn’t “hack” into your account but simply used credentials they were once privy to.
- In many relationships, passwords are shared for convenience. However, once separation occurs, the use of previously shared passwords without permission becomes unauthorised access.
- If your ex used deception to reset passwords or access accounts in other ways, this may be illegal, as it may amount to fraud and a breach of the Computer Misuse Act 1990.
The family court is primarily concerned with ensuring a fair division of assets and considering the welfare of any children involved. Behaviour like unauthorised account access may not always affect these matters directly, but it can be significant in certain circumstances.
If your ex-partner has accessed your private accounts, this may amount to a breach of privacy. Although family courts rarely focus on issues of privacy, if the breach was used to manipulate the financial settlement or custody arrangements, it could be relevant.
If your ex used the information gained from accessing your accounts (such as bank statements or private emails) to gain an unfair advantage during negotiations or court proceedings, this could be brought to the attention of the court. Using unlawfully obtained evidence is not permitted, and the court may disregard such information if it was gained through improper means.
Sometimes an ex may access your accounts to harass or control you, this could be relevant to non-molestation orders or issues around domestic abuse. The family court takes domestic abuse seriously, and if unauthorised access is part of a broader pattern of coercive control or emotional abuse, this can affect matters such as child arrangements and lead to protective applications for non-molestation or occupation orders.

Is there anything I can do post-divorce?
If the divorce proceedings have concluded, but you suspect or know that your ex-partner has gained access to your accounts, there are several actions you should take:
- The first and most obvious step is to change the passwords to all your accounts. Use strong, unique passwords and enable two-factor authentication (2FA) where possible to enhance security. Even if you suspect access but cannot prove it, changing your passwords should prevent further breaches.
- For sensitive accounts like email or bank accounts, contact the service provider to alert them of potential unauthorised access. Many services can provide logs of login attempts, which might give you some evidence if needed.
- If your ex-partner accessed your accounts without permission, this could contravene the Computer Misuse Act 1990. You may be able to report this to the police or Action Fraud, the UK’s national fraud and cybercrime reporting centre. While this may not directly impact the divorce settlement, it could provide a legal remedy for the privacy breach.
- Even post-divorce, you can consult a solicitor to assess whether any unauthorised access affected the financial settlement. If substantial breaches or fraud can be proven, you may have grounds to challenge the outcome of the settlement. However, such cases can be complex and costly, so a lawyer’s advice is essential to evaluate the likelihood of success.
How can I prove unauthorised access if I suspect it?
In many cases, the challenge lies in proving that your ex-partner accessed your accounts without permission. If you have suspicions but no concrete evidence, there are a few options to consider. Some services allow you to view login histories, which may show suspicious access. This can help substantiate your suspicions.
While it may be tempting to try to catch your ex accessing your accounts in real-time, this can be a risky strategy. It is usually better to focus on securing your accounts and gathering evidence afterwards, rather than trying to set traps. If your ex has already accessed the accounts, the damage may already be done, and your priority should be to prevent further breaches.
Is it worth pursuing legal action?
Deciding whether to pursue legal action for unauthorised access depends on several factors. If the access has caused you significant financial or emotional harm, or if it affected the fairness of your divorce settlement, legal action might be warranted. However, litigation can be expensive and time-consuming, so it’s important to weigh the potential benefits against the costs.
In many cases, the most practical approach is to secure your accounts and move forward. Changing passwords, improving account security, and ensuring that your ex no longer has access to sensitive information may provide you with the peace of mind needed to move on after a divorce.
