My soon to be ex wife has given my business partner copies of my personal bank statements.

Background: there were a couple of financial errors within our company accounts which were my fault and have since been resolved between myself and my business partner.

Issue: when the issue arose, my business partner went to see my estranged wife, whom he knew had access to our old joint account, which by agreement I was using as my own personal account for the time being. When he asked her for the information, she printed off all statements and gave them to my business partner.

Baring in mind that her name is also on the account, I am asking if she had any right to firstly access the information and secondly share the information without my consent.

Thank you in advance for any help
