Is paternity testing mandatory in the U.S.?

No. Currently, paternity testing in not mandatory in the U.S. and there are no specific laws that currently require a paternity test to be performed.

Although there are no laws for mandatory DNA paternity tests. In 2022,Tennessee Rep. Antonio Parkinson’s proposed bill will insure that the actual biological father is listed on the birth certificate of the child. This will be done by performing a paternity shortly after the child is born. The Tennessee Department of Human Services (DHS), who oversees the child support program, is fighting vigorously to kill the bill. Therefore there is no guarantee that this bill will pass due to the amount of money Tennessee DHS  will if this bill was to pass.
