Me and my ex have gone through this too. I prepaid all of my medicals during my pregnancy. Lance (my ex) agreed to reimburse me for half of them which yes legally hes not obligated to do. we signed an agreement that had all of the medical bills attached to it along with a signed agreement i had with my OBGYN for the prepayed hospital bill. AFTER he signs the agreement he argues the authenticty of all of the bills so i go on to my online banking and pring out the checks that i used and the credit card statements of where i paid all of this. And he still wouldnt pay me for them, has not paid child support or anything. The only money spent with any reguards to the child was a paternity test that his grandmother paid for that was 600.00.
