What is the consequence if both claimants retract their claim of paternity after having made it?

Primary text

If both claimants retract their assertion of paternity, the retraction is not accepted. This is because lineage is a right belonging to the child; therefore, they cannot retract their admission, similar to an admission of any other right belonging to the child, or when one person claims paternity, it is established, and then he denies it.
