I agree with your father. I think your H should drop the papers off when you are not there. You can then read them at your leisure, get input from whoever you like, etc.
I don't think a sit-down with him is a good idea either. Too much chance for things to go hairy.
The trouble with having an open mind is that people put things in it.
