I have a question and no hate comments please. I've never done this before.

So my other 2 sons have Godparents. They were mainly chosen by their father. He didnt want any of my family to be God parents just because he didnt like them. Well we are expecting our 3rd. And currently going through a divorce. Am I able go pick Godparents without him? He doesn't really care for God parents he doesnt see the point. But I was wondering if I could choose without him? How does this work. If anyone has advice please let me know. Also our attornys told us not to speak to eachother until more custody issues get resolved.
