Custodial rights

I and my wife are going through the divorce. We are both expats. I work and she does not work. I am her sponsor. We have a one-year-old daughter.

Who gets the custody of the baby after divorce?

Once we get divorced, who will be her sponsor in the UAE?

Does she have to leave the UAE?

If she gets the custody, how can she stay in the UAE without a sponsor?

If she does not have a sponsor, can I get the custody of my daughter?
