Hello, my boyfriend's ex girlfriend has fallen pregnant and has just had the child. She's harassing my boyfriend and forcing him to take a DNA test as she has put in a claim for child support from him, but he believes it is not his child and now has to pay to travel to have the DNA testing done. He had to take days off work which we can not afford; we are really struggling financially, so we were wondering if the child turns out not to be his, can we then put a claim to get our child support money back, or have her pay it back to him? Or do we have to just lose all that money and income because of her harassment and greed?
