The baby's mother and I are not together, and as such i am not on the birth certificate, although we have agreed to re register him so that i will be on the certificate. What i am worried about is the fact she has something of a reputation for being promiscuous and although she says she is 100% sure i am the father, i know that there could be a chance I'm not. Now I'd love to be the father, I've spent time with him and hes amazing and i also feel like i am more than likely the father, but i don't want to be raising and supporting someone else's child, and basically being used for my money which many people I've spoken to seem to think. now the reason I'm asking this question is, despite it seeming a bit backhanded, it seems like the only way to get a pat test as she hasn't consented to one when i asked before, which struck me as odd given that shes so certain i am the father. So if we do re register the child, and i am on the certificate, can i demand a paternity test? THIS IS NOT A WAY FOR ME TO GET OUT OF SUPPORTING THE CHILD, I WANT HIM TO BE MINE BUT I JUST NEED TO MAKE SURE.
