If he is named as the father on the birth certificates, even if he is not the biological father,
he is responsible for their support. If he is not named as their father and has not adopted them,
even if he married their mother and has provided some support while married, he would generally not
be obligated to support them after divorce unless there were some extenuating circumstances requiring
him to do so.
