Can I change my visa to another company if I have a travel ban against a loan?

I got a travel ban from a finance house. I don't know if it's a civil case, one advocate said to me it's a Dubai court travel ban.

My cheque is not bounced yet or they didn't submit it yet, but I have a travel ban. Now I need to change my visa to another company.

How can I do it? How do they file a civil case without bouncing a cheque?
