Does my 18 year old pregnant daughter have to take a paternity test in the state of New Jersey?

My 18 year old daughter just found out she is 10 weeks pregnant. The boyfriend and his mother tried to get my daughter to have an abortion---she refused. Now the boyfriend and his mother want my daughter not to go to college where she has been accepted but to move to Georgia (parents will put up their son, my daughter and the baby in an apartment and pay the rent) so their family will be together while they retire. Does the boyfriend (19 years old) have grounds to force my daughter (18 years old) to have a paternity test?
