Can a non-Muslim father claim the custody of his child as per the new personal status law?

Hello,

I would love to understand the new child custody laws in-depth for non-Muslim residents.

My wife was granted our child's custody in the judgment of the first instance court but I have appealed against it.

Having said that, I have a family here in Dubai to support raising my son whereas my wife has only herself (she is currently employed) and has a nanny only.

How can I get full custody of our son or maybe apply for joint custody as per the new law?
