Sorry this will be so long but we do not really have the money to throw at a lawyer prematurly. My brother(21yrs old) got some girl pregnant (20yrs old) pregnant. They come around and tell the family everyone is super excited. My brother has been in love with this girl for a year or so and he has a good job so it was not bad news. A few months later the real story comes out. It is only a 50% chance the baby is my brother's. He is heart broken. Apparently she was living at my brother's house and squishing this other guy at the same time. She tells my brother she want's to be with him and that was the biggest mistake of her life so on and so forth. Out of the 2 guys my brother is the obvious choice. He has a great job, brand new house. While the other guy works at Sonic (no offense to sonic workers) and is quite bad off on drugs. My brother says he wants nothing to do with her but if the baby is his he WILL be there for the baby and be a great father. The rest of the months are filled with drama as she goes back with the loser since my brother told her he wanted nothing to do with her. Now that we are really close to the birth she tells my brother that they will only be getting one DNA test and that my brother will not find out if the baby is his or not since Sonic wants to raise the baby with her instead. THAT is my question, is it legal for her to deny my brother a DNA test and see what is potentially his child? If you have any advise I would be very thanksful
<bot>: Brother got girl pregnant.... maybe. She will not let him get a DNA test to see if it is his. WTF?
