Let’s say that I suddenly had access to go fuck yourself money. More money than anyone could think possible.

How could I use that money to get sole custody of my children? Is there an Uber expensive lawyer that could guarantee it? Is there another way I’m not thinking of?

This is just a hypothetical, but I’d like to keep it to legal options. I know what a hit man does and could do for me in this situation, but that’s not where I want to go with this fantasy.
