In may of 2012 my now fiancé became pregnant we were split up and seeing other people, however we were still seeing each other. I understood the chance that my daughter may not be mine. But I was there anyway and didn't want to ask. Then an ultrasound determined that my fiancé was 4 weeks more into the pregnancy then we initially thought which would mean my daughter is mine. However my fiancé was seeing one other giy during our breakup. And now he's threathning to go to court get custody etc.. My question is do I even have to go to court for this even after signing the declaration of paternity..
