so based on what I am seeing in the Rambam I think the hierarchy goes like this. First what people say. That overrides everything else. Then comes what the woman says. And then status quo. How do you see this? By the law of Truma. Even when most people in the city are pasul, but no one is saying anything, and she claims she had sex only with kohen and she gives birth to a male child, she can eat truma. But if people say she had sex with others, then no. The comes the case of a betrothed woman. She is pregnant and claims the child is from her betrothed husband. She is believed about herself and her child unless the betrothed husband denies that he had sex with her.0-----------------------So based on what I am seeing in the רמב''ם I think the hierarchy goes like this.
