Establishing paternity has several important legal consequences. However, before paternity can be legally established, a party alleging paternity must have reliable evidence to present to the court.
In the past, paternity could be difficult to determine and courts were often forced to rely on testimony or other anecdotal evidence in order to do so. However, recent advances in technology have made DNA paternity testing readily available and relatively inexpensive. DNA testing provides incredibly accurate results to private parties and the courts.
There are several types of DNA paternity tests that can be performed both before and after the child is born. There are three main tests that can be performed prenatally: Amniocentesis, Chronic Villus Sampling (CVS), and SNP Microarray.
