Can you take paternity test with another relative if the suspected father is deceased?

In some cases, it is possible to conduct a paternity test using DNA samples from a close relative of the deceased suspected father. This method involves comparing the DNA of the child to the DNA of the relative (for example, a sibling or a parent of the deceased) and analyzing specific genetic markers to determine whether the relative can be excluded as the biological father. If the relative is excluded, then the child must have inherited their relevant genetic markers from the deceased suspected father.

However, it is important to note that the accuracy and reliability of a paternity test using a relative's DNA may be lower compared to a direct comparison with the DNA of the deceased suspected father. This is because the relative's DNA may share only partial genetic information with the suspected father, and there is a higher risk of obtaining inconclusive results or misinterpreting the data.

For this reason, it is recommended to consult with a genetic testing expert or a legal professional to determine the best approach for establishing paternity in cases where the suspected father is deceased. They can evaluate the specific circumstances and determine whether a paternity test using a relative's DNA is appropriate and provides sufficient evidence for legal purposes.
