passing on private info

[Guince]

I have recently sent in evidence of my finances to my husbands solicitor for the clean break order. This consisted of a payslip, a statement of my pension details and screen shots of credit card details - all of which had sensitive information on.
My husband rang me several days later to tell me his solicitor had scanned all my private info I had sent, and forwarded it to him.
I did not want my husband to have this info as the solicitor said the evidence was to be sent to him, no mention about my husband getting this information too.
My husbands new partner is also under suspicion by the police for setting up fraud accounts with shopping companies in my name, and now she can probably get access to my private info.
Is this a breach of my data protection rights? I'm so angry but I don't know what steps to take. Really appreciate any help and advice.

There doesn’t seem a lot of data protection when it comes to divorce. It is standard practice to have to provide all bank statements for a year and details of all finances and they are sent to the other party. I was very angry about having to do this - not because I have anything to hide but because it is so intrusive. I don’t want to be in a situation where someone queries every coffee I buy. However, nothing is private in marriage, it seems. His statements were eye-opening. I didn’t need to feel guilty about coffees.

Lol, my exe's barrister trawled my credit card statements and declared I was spending lunch money on "fripperies at Waitrose" while my poor ex was forced to make herself a sandwich at home.

A sure case of financial abuse if ever I saw one lol

Has your solicitor not sent you cooies of his financial information?

*copies

His solicitor said we send the evidence to him, he'll draft the consent order then send it to each of us to agree. His solicitor has not sent me any copies of my husbands evidence at all. At no point in his solicitors letter did it say my evidence will be passed on to my husband, and nor did I give permission.
I understand we both need to see the figures on the drafted copy, but to actually give the documents to my husband has given me concern, especially when they show my NINO and other sensitive information.
