In some jurisdictions the husband is always the legal father, no matter who the bio father is. And in some jurisdictions the paternity can be changed in favor of the bio father only if there has been made an official paternity test by the request of the child's mother (not the husband or the bio father!) AND the husband agrees to letting go of his paternal rights.
