The individual did not provide the gametes used in the assisted reproduction;

The individual did not consent to the assisted reproduction;

The individual and the parent who gave birth to the child have not cohabited since the date of the transfer that resulted in the pregnancy; and

The individual never openly held out the child as the individual’s child.
