My ex hacked my email, what legal action can I take? (UK)

When couples separate, they naturally tend to focus on macro issues, such as the family home, finances, and arrangements for the children. This is when the micro issues such as changing security settings on devices or passwords can become lost in the noise. You may even have actively shared these details with your spouse when you were together. But what if they decide to misuse their knowledge?

This article answers these questions and more.
