How much could be % of paternity fraud? I personally 2 cases where man is victim of paternity fraud and in both cases in no way those men are assholes or violent.They are just your avg guys who work 9-5 job .But the real father of those two different kids is one same guy .He is sort of muscular and rich .Men don't know they are raising other man kids .So is there any case you know personally where man either knows or doesn't know he is victim of the same
