DNA Testing Between Grandparents and Grandchildren


There are many reasons why grandparents become involved in a paternity test – and even take tests themselves in order to set their minds at rest about the parentage of their alleged grandchildren. Experts agree that grandparents have a lot to contribute to the welfare and wellbeing of grandchildren, so it’s not surprising that many of them go to such lengths to determine their rights.

Paternity Test For Absent Father

Where a father has decided not to accept responsibility for a child, the grandparents may decide that they still want to be involved, or at least to see the child or children on a regular basis. This can be difficult, as the relationship between the mother and the grandparents may be affected by the absent father. If the mother is maintaining that the absent father is not, in fact, biologically related to the child, the grandparents may wish to take a grandparents DNA test themselves, which although not as accurate as a paternity test, may be able to show a significant likelihood of a relationship.

Paternity Test For Deceased Father

There are cases where the biological father has died and the grandparents are the closest remaining contact on the father’s side of the family. Where the paternity has been in dispute, a court may order that the grandparents undergo DNA testing in order to show whether there is a biological relationship with the child or not. This can be important, as grandparents may request access to the child.

Grandparental tests can also be used to establish the identity of the father. This is because once a biological relationship has been established between grandparent and grandchild, the father of the child must be a child of the grandparents. If fatherhood is disputed between brothers, the grandparental test will not be able to distinguish between them. If there is only one son, however, the test will be enough to prove that he is the father.
