Changing work visa while there are pending dues with the current employer

Hi,

I have been working in the DHCC Freezone for the past 3 years and a half. The employer owes me pending salaries amounting to almost 8 months plus end of service.

The employer has no intention to pay the money and is claiming that they don't have any money in the account. All the staff in the company are suffering the same fate.

I have managed to secure a job with a different employer and want to change my visa to the new employer.

Can I change it without signing papers stating that I have received all my dues? If not, then what is the legal procedure to change the visa?

Does a court case enable the court to allow me to switch?
