Understanding Paternity Disavowal: A Legal Overview

Understanding Paternity Disavowal A Legal Overview

Discovering that one is not the biological father of a child, previously believed to be one’s own, allows for paternity disavowal, absolving all paternal responsibilities. How does the process of paternity disavowal work? What evidence must be presented to the court to demonstrate a physical relationship between the mother and another individual?

In general, the preferred evidence for both paternity recognition and disavowal is DNA testing through blood sampling. However, specific timelines must be adhered to, beyond which our legal system protects the apparent situation to avoid prejudicing the minor’s interest in having a father, even if only “adoptive,” and the emotional bond that has now solidified.

This concise article explores the process of paternity disavowal, including the procedure, evidence, and timelines that must be respected.
