The ownership of a code of a web application

Hello,

I represent a tech-based marketplace company registered in a Freezone, in the UAE.

This is in regards to the UAE's law regarding the ownership of code when there is no clause mentioned in the agreement. One of our products (web application) is being developed by an agency in the UAE.

While we do have agreements in place, there is no clause regarding ownership of code. In the situation mentioned above, I've heard that the ownership of code either goes to the author or the agency that employed the author. Is this true?

Your assistance and help would be of great help.
