What do you think of this case concerning the co founder of Moneysupermarket.com?
He raised three sons only to discover they weren't biologically his when his doctor told him he was infertile and had cystic fibrosis after he had divorced his first wife and tried for children with his new wife.
Apparently paternity fraud is more common than we think. One man in America wanted to donate a kidney to his son only to discover he was not a match because he was not related to the boy.
What I don't understand is why you wouldn't use contraceptive if you were going to have an affair.
