Deoxyribo nucleic acid test is a process of analyzing the structure of DNA of a person, but it is put to a lot of uses. Thus the DNA of a person is quite unique from that of another; it is used as a method of identifying the person. There are several scenarios in which Deoxyribo nucleic acid test is legally significant. Here we check out the many reasons for which this testing could be legally required.



1.One of the primary purposes of DNA testing is to establish paternity. There are cases when the child is unsure of whom his/her father is, or the father is not sure that the child is really his. This might be a problem in cases of inheritance or in cases when there is a divorce and upkeep for the child has to be paid by the father. Courts will generally use a DNA paternity testing in such cases to find out whether the kid biologically belongs to the father.

2.Criminal investigations also require a lot of DNA testing. Most times, biological samples such as hair, blood, skin cells, semen, etc. are found at scenes of crime. These could be a very accurate way of determining some people associated with the crime. Since all these biological samples contain DNA, and DNA is unique for every person, DNA heritage testing can be beautifully used here to investigate the crime.

3.DNA testing is also used to determine by immigration officers in some doubtful cases. For example, consider a person wishing to get into a country claiming someone there is his/her father. In that case, a DNA paternity testing will establish the paternity legally without doubt. Sometimes, this might also be needed for aliens who are staying with people they claim to be their parents in another country.

4.On a broader scale, genealogical DNA test can be used to historically determine the ancestry of a person. People are getting these tests done to find out about their own ancestors. While this is not at all legal, sometimes it might be important in cases when there is a problem connected with inheritance or for establishing lineage for legal reasons.

It must be noted that there are several home DNA tests available today. While these tests are quite accurate, their results will not be admissible in courts of law. For legal DNA tests, only tests conducted by professionals will be accepted.
