Happily, from what I've seen it's hands down the father who has the most stable career and home and environment. As well as it's where his kid has grown up all of his friends are there, school, etc

I think that assumption is correct, I just want to help find them a tried and true attorney

From what I hear, the mom isn't all that great but as far as what the courts would see idk

The courts favor the mother... In general, obviously

The father, my friend, is looking for an attorney to fight for full custody

Right well its not for me, i myself am childless, but the person in question, the mother is trying to move across the country with her new boyfriend and the father isn't interested in only being able to see the child during the summer. He wants him full time
