If you don't think there will be a fight about anything, you can just allow him to go live with his grandfather without any kind of court action. If you want to be formal about it, you will need a petition for custody filed by the grandfather with a signed consent by you. The Court will need to notify the biological parents and will likely hold at least one hearing. So long as all parties are in agreement, you should be able to do with with an agreed judgment entry signed by yourself and the grandfather.
