Determining how prevelant paternity fraud is makes for some informative reading. One of the more credible sources on this subject is the AABB. In 1995, the AABB (American Association of Blood Banks) reported on test results from 280,000 paternity tests performed in their labs that year. Some of the report findings were: 1) Roughly 30% of the time, test results ruled out the named father as the biological father; 2) Marital status did not statistically alter the results. I.E. married women were as likely to misrepresent paternity as were single women; 3) The percentage was greater than 30% if it wasn’t the woman’s first pregnancy.
Should there be a cause of action for paternity fraud? | Gregory S. Forman, P.C.
A colleague of mine, T. Ryan Phillips, emailed me an October 1, 2012 Tennessee Supreme Court opinion in the case of Hodge v. Craig, 382 S.W.3d 325 (TN. 2012). That opinion approves a cause of action for paternity fraud within that state. With the rise of paternity testing, this cause of action...

Had heard that stat previously that in a classroom DNA test, suddenly nearly 1/3rd of children were found to be from another man. But that could have just been one random area.

Very interesting indeed.
I still think I need to triple check this, but if true it is astounding.
