This is an important legal distinction. The person listed on the birth certificate is the legal father — whether or not he is the biological father.
The legal rule: The father listed on the birth certificate IS the father in the eyes of the law. Biology is secondary to the legal presumption of paternity.
What this means for adoption:
- The legal father (person on the birth certificate) is the one whose consent is needed or whose abandonment must be established
- If the legal father has had no meaningful contact with the child, abandonment can be established regardless of biology
- The biological father (if different from the legal father) typically has no legal standing unless he's taken legal steps to establish paternity
Rare exception: In extremely rare cases, if the court becomes aware of a biological father, the judge MAY require his rights to be addressed. But this is uncommon in stepparent adoption.
Practical advice: Focus on the father named on the birth certificate. That's who the court considers the legal father, and that's whose rights must be addressed for the adoption to proceed.
