I live in another country (Thailand) and my son lives in Indiana where the agreement of paying child support was made with the court. My son will be 21 in just a few months, he has his own child, he is in the Reserves and has been for almost two years. I believe he still lives at home with his mother. Can I stop paying child support and if so... what do I do.. do I just not send anymore checks or do I have to get permission from the state of Indiana before I stop. I would greatly appreciate it if someone could answer this question. :)
