DNA testing

My boyfriend has a child (possibly his). But he believes with all his heart that the child is his. I have my reasons of doubt, based on many conversations (private) we have had. I want to know if there is any way that i can do a dna test on him and the child without the mother of the child and my boyfriend knowing? If the test proves he is the father i will leave it be.

There are ways to do a test in secert, the best way is swapping the inside of the cheek. However if you do this in secret it will cause a greater issue then what is going on here, I would suggest you sit and talk to him express your concerns. I had to go to family court to get rights for my daughter due to the fact that I was on no birth certificate and my name was not with her the courts ordered a DNA test. This is an expensive and horrible experience (family court) as woman don't like to be questioned if they know who the dad of the child is. Keep it between you and him. Express why and maybe a bit of facts would help get his approval first.
