I am being told by two different people who work in the court system, I want to know the truth about how long or at what age do I have to pay support? Is it 18, or 21? Now I hear if they attend college it is 21 yrs. For the support to be paid. I have three children who are not in college and never have been but I am being told to pay for them until they are age 21. What is the truth? Thank you.
