Transferring mother's residence to be under father's sponsorship

My family is currently overstaying in the UAE for over a year now as my mother lost her job.

We want to transfer it to my father’s sponsorship. Is there any possible way to get this done since we’ve been delaying it due to financial constraints?

Also, since there is a financial case; we are hesitant to visit the immigration directly. Any advice?

We want to solve this as soon as possible and reduce the fines as much.
