Tomche- easier said than done. You have to look at the other side too. If you look through Chazal, you see the tremendous concern they had for agunos, and how they sometimes “cut corners” to protect them. The answer to the issue is not to ignore pre-nups, because unfortunately there are men who take advantage of the system and are willing to make women agunos for their own benefit. If according to major poskim that prenups do not create a get meuseh, and they protect women from becoming agunos, that also has to be taken into account. I don’t know the answer- safek mamzerim vs. agunos, but it’s not that simple.
