I have a rubric contract that is in one of my Lesbian Conception books that I would have to get checked over by a legal professional. However I know if a child is conceived with sperm through any method other than penetration, legally the donor has no right to the child (although I'm sure it could be contested). Nonethless, yes.
If he's expecting to be dad, and to be a primary carer, then it won't be happening. But I don't think he is.
