Yes of course. Pregnancy does not emancipate her and you are obligated to care for her until she is 18. She and the father will have a hard enough time to support the child, they do not need to support themselves.
No. She is still your child and still needs to be supported.
No. The father of the pregnant daughter has no legal obligation to support her child. That responsibility belongs to the biological father of the unborn child assuming that the pregnancy is not terminated nor the child placed for adoption or parental rights terminated by the court.
If she is married, no. If she is unmarried, yes.
What she did with her pregnancy has no influence on the child support you pay for her. Even if she would have kept the child it would not have made any difference. pregnancy does not emancipate anyone. You are still obligated to support your daughter until she is 18yo.
The daughter being pregnant does not eliminate the responsiblity of a parent to support their child until they reach the age of majority.
Depending on the state yes. I know that in Missouri the rule states if the child is 18 or if in college 23 is the age that child support payments end. That means that unless the child marries prior to their 18th birthday or 23rd if still in college then the payments continue regardless if they are with child or not.
If the daughter is no longer living with her mother, and is independent, then you could petition to end child support. If she is still in highschool, you might continue to pay with the agreement that the money transfers from mother to daughter.
