So, when it is time to go to his dads and s10 refuses, do I have to force him to go?

IMHO no you don't force him to gol You let him vote with his feet and then you let H sit with him to find out why he doesn't want to go. It may take a few attempts for s10 to do this and for him to feel brave enough to say what he feels but with love and support he will do eventually. This way you cannot be accused of manipulating your children and therefore inadvertantly finding yourself in court for the same reasons you are considering taking H.
