Filing a divorce case for domestic violence

I am looking for legal advice on divorce in the UAE.

I am Belarusian non-Muslim and my husband is Tunisian Muslim. We have 1.5-month-old daughter Belarusian citizen. The marriage contract was made in Tunisia and legalised in Tunisia, the UAE and Belarus.

The father is mentioned in the daughter's birth certificate. Since September, I stayed in Belarus and I am here with a daughter now.

In April, I am travelling for the UAE visa validity (6 months) just for a week and coming back to work in July from maternity leave.

I want to file for divorce as my husband had aggressive behaviour towards me, was physically violent 3 times during my pregnancy and abused me verbally.

He also refused to support me while pregnant, and since August 20th, 2017, I was not able to work and I had no source for living while paying AED 5460 loan monthly, that was the reason of leaving back to Belarus for maternity.

Can you please advise if my husband can ban my daughter while coming in April on a tourist visa? Also, what is the actual procedure to file a divorce in my case?
