Ex-partner refuses to show bank details

Questioner

My ex-partner does not want to provide an overview of his bank accounts. We are getting divorced and on 13-6-2018 the application for our registered partnership was requested. My ex-partner must provide an overview of all his accounts from that date, but he refuses to do so. Can I do anything about this? I do have a lawyer, but it is taking far too long for me and I have the idea that she is not getting anywhere with his lawyer. It has been going on for over 2 years now. In November 2020 we had a lawsuit and the judge also said that my ex-partner must show his bank details.

Lawyer

Dear Madam, If your ex does not provide any information, you can -again- claim this at court and demand a penalty payment. I am happy to represent your interests. Do you have any questions? Please feel free to ask. Yours sincerely,

Questioner

I have a lawyer because of the divorce. Unfortunately this is taking much too long. Do I have to go back to court via my own lawyer or can I take another lawyer for this?
