If this is what you mean by "emancipated": I'm pretty sure you're not legally obligated to support her financially, as long as she is at least 18 years old.
No, fourteen is much too young. Most places require the minor to be at least 16 and show proof of support to get emancipated.
No
In my view, such a child should be considered "emancipated" and, therefore, support should end.
That's up to the judge.see link
He already is emancipated since he is 18.
Not likely, especially if she is emancipated (i.e., self-supporting).
Yes. Until and unless the child is emancipated, you are still responsible regardless of other income. The support from your daughter's boyfriend is probably for your grandchild.
In Indiana, a minor must be at least 16 years old to petition for emancipation. They must also show that they have a source of income to support themselves and are capable of managing their own affairs.
In general, emancipated children are not eligible for child support - they are considered adults.
Regardless, child support continues until age 21. see link
Yes until she is emancipated. It might also be a good idea, since you allowed her to move, to see to that the child support goes directly to her and not to the mother unless she moved with them.
Yes, to the limits on your state, but you can file for custody or to have her emancipated. see links below
