Spousal infidelity: can secretly collected evidence be used?

You find out your spouse is being unfaithful, you find a way to check his/her personal phone or computer, or otherwise access the communication apps he/she is using, and the infidelity is confirmed. You immediately take screenshots or copy correspondence, collect evidence of infidelity and prepare to use it in divorce proceedings.

Question: can you submit this data to court and use it as evidence?

Despite being married, each spouse remains an individual, possessing distinct personal rights, including the right to privacy. Personal communications, such as correspondence, telephone calls, letters, and e-mails, fall within the scope of this right, ensuring that each party is free to communicate without unwarranted intrusion.

The right to communicate privately and without interference is enshrined in the European Convention on Human Rights (ECHR), specifically under the right to respect for private life, safeguarding the confidentiality of personal communications.

If you have accessed your spouse’s personal phone, computer, or communication app account without their express consent, this constitutes a violation of their privacy rights. Any evidence obtained through such unauthorized access is deemed to be unlawfully acquired and is inadmissible in legal proceedings.

Relevant case law highlights that, in divorce proceedings, courts have found that one spouse violated the other’s right to private correspondence by searching their personal belongings and reading their private communications without consent.

Furthermore, the unlawful collection and use of such evidence may expose you to potential criminal liability if your spouse reports the matter to the authorities, triggering a pre-trial investigation.

It is important to note that, without your spouse’s knowledge and consent, you are prohibited from accessing personal correspondence, inspecting private belongings or documents, or engaging in any form of surveillance, such as installing eavesdropping devices in a vehicle or residence. Such actions are not only a breach of privacy but could also result in significant legal consequences.

So how do I prove my spouse's infidelity?

If you suspect infidelity, even after reviewing personal correspondence, you may still seek additional evidence to support your claim. This can include photos or social media posts documenting time spent with another person, creating a “timeline” of such photos if no shared ones are available, verifying that both your spouse and the third party were in the same location at the same time, or checking whether your spouse’s bank or credit card statements indicate purchases made at the same location.

In divorce proceedings, proving infidelity can be challenging. However, with the appropriate legal strategy and evidence gathering, it is possible to demonstrate that your spouse has breached one of the fundamental duties of marriage—loyalty to their spouse.
